/AoIP

1.3 Fea ures

D612 console is a compact, solid and elegant unit;

with a great lexibility or interconnection. It in-

cludes USB digital I/O which brings digital link with

the computer; avoiding the use o sound cards in

the computer.

D612 has 5 100mm pro essional

Conductive-Ce-

ramic ader o with ETM-VCA control that o er a

li e utility o one million operations (over 15

years). It is the best solution or small and

medium radios; and or auxiliary recording stud-

ies in great stations.

1.3.1 Inpu channels

There are 2 microphone channels, that manages

our microphone inputs. Each input has dual input.

Main inputs MIC-1 and MIC-2 supports phantom

power o 48V, switched rom the ront panel. Mic

channels have a processing stage that includes 4

bands equalizer and automatic dynamic range

compressor. Each microphone channel can be

sent individually to the air signal (PGM) or as-

signed to the processing stage. MIC-3 channel can

be switched to AUX stereo line input.

Each mic ader can manage two dynamic micro-

phones. At the rear panel you ind 4 XLR inputs

(MIC-1a; MIC-1b; MIC-2a; MIC-2b). The built-in

dynamic compressor compensates the level be-

tween the microphones. It's appropriated that

mic's connected to the same channel are the

same model.

3 LINE channels allow connecting up to 6

sources. Channels 3 and 4 manages unbalanced

analogical inputs (Line-1 and Line-2) and balanced

inputs (Bal-1 and Bal-2) whereas channel 5 are

digital, with direct connection to the computer via

USB. In addition, all channels have one analog

auxiliary input.

All the channels count on a gain control, that take

e ects on the selected input (main or auxiliary).

“Telephone Hybrid” manages one land telephone

lines (2 wires) and one cellular phone linked via

Bluetooth. Both can be in con erence. The use is

very simple, since many unctions are auto-

mated. Additionally, the console has send and

return connector or external hybrids.

1.3.2 Moni ors

The monitoring area distributes the signals to the

loudspeakers and headphones on the studio and

the control room.

S udio & Con rol Room has a unique level knob

or loudspeakers and headphones; and the assign-

ment switches that allow select between ON-AIR

signal (external tuner), console output (PGM) or

recording output (REC). Usually the level in the

console is ixed; since a headphones mixer allows

to manage each headphone and active speakers

has it own level knob.

CUE moni or The console has a built-in loud-

speaker or cueing, with its own control level. CUE

is an internal send that allows listening to the audio

signal previous to the ader. The cue signal also is

sent to the Control Room headphones.

Additionally, monitoring section contains the

Talkback circuit; that operates as well in combi-

nation with loudspeaker CUE to engage in a pri-

vate dialog rom the hybrid with a telephone call

without disturbing the on-air signal.

Page 5 www.SolidynePro.com

1.3.3 Ou pu s

Solidyne D612 has wo main ou pu s named

PGM (Program) and REC (recording). Phone lines

are sent only to PGM.

In addition it has an USB digi al ou pu that ap-

pear in the computer as external sound record-

ing devices (USB recording devices) and sends

the program signals.

The outputs are:

1. PGM, The PROGRAM output is used the

send the signal to the air.

2. REC, used to recordings (and allows to lis-

ten a channel in the main monitors without

send it to the air .

3. PGM/REC USB, program or recording out-

put is also available via USB.

4. PGM over Ethernet (optional): Available

in models with the expansion /IP. The con-

sole can send RTP streaming to link with

the transmitter plant; or mpeg streaming to

upload to an Icecast server (see Chapter 4

– Models D612/IP

D612 has send & return connections or ex ernal

hybrid. The audio rom the external hybrid enters

trough the “hybrid channel” and operates just as

the built-in hybrids; which continue being operative.

Please note that land lines o internal & external

hybrids will work in con erence.

The Tally ou pu allows the direct connection o

ON-AIR LED’s lights. Tally activates when opening

the mic channels. The mixer has built-in tally LED.

TALLY OUTPUT LOAD DOES NOT HAVE TO

EXCEED 120mA (two Solidyne ON-AIR lights).

If your radio uses the old incandescent light

bulbs, a 1 V relay must be connected.

1.3.4 ETM – VCA faders

Using a technique o control called ETM-VCA

(Electrometric Voltage Controlled Ampli ier) the

aders DO NOT manage audio signals. The

change on the level is made using low noise ampli-

iers o great stability. The main aders only handle

control signals that modi y the gain o the elec-

tronic ampli iers. For more in ormation please visit

our WEB site.

The main advantages o this technology are:

•Eliminates the noisy signals due to dirty

faders.

•Eliminates the maintenance and improves the

life of faders.

•Gives a perfect stereo tracking (less than 0,1

dB error) between Left and Right channels.

•Allows using Conductive Ceramic faders of

two million guaranteed operations (about 15

years of use).

CHAPTER 2 Installation and wiring

2.1 Overview

Installation o Solidyne D612 doesn’t present par-

ticular jobs. However, keep in mind the basic rules

or all pro essional audio installations. The bal-

anced inputs o the D612 uses DIN-5 multipin con-

nectors (provided with the console). In option, you

can acquire the Solidyne wiring kit (MNG612),

which include all the cables and connectors

needed or the set up.

For console grounding use the rear side GND

bronze ip with a mm cable to a good buried

cooper bar.

2.1.1 Parasi ic signals

All unwanted signals that appear in audio lines

usually consider parasitic signals. A common type

are denominated humming, low requency signals

(multiples o 50/60 Hertz) caused by the interaction

o electromagnetic ields coming rom the AC line.

When the inter erence source is a magnetic ield

(generally originated in a supply trans ormer) the

resultant inter erence will be denominated electro-

magnetic humming. When the inter erence is due

to such electric potentials as cables that take sup-

ply tensions, that are elevated in comparison with

the audio signals present in the circuit, you will be

in presence o electrostatic humming. The distinc-

tion is not merely academic, because the resolu-

tion o a problem supposes the knowledge o the

noise type to apply the correct solution.

Examples: To minimize the reception of electromag-

netic humming in the wires, remember the following rule:

"THE AREA AMONG TWO AUDIO WIRES WILL BE

MINIMUM." It implies that the cables will be tied very

close, like the shielded twisted pair audio cables. They

should pass far away from any transformer or devices

that manage high-intensity currents. Is important to re-

member that a wire can be good shielded, but if his con-

ductors don’t complete the conditions of minimum area it

will be susceptible to take magnetic humming.

Other parasitic signals are: AC HUM, RADIO FRE-

QUENCY and CROSSTALK. As hum noises like

the radio requency are originated by electromag-

netic ields o high requency; the irst ones are

originated by disturbances due to the connection

and disconnection o equipment’s to the AC line,

the seconds ones are generated by communica-

tions transmitters or industrial equipment. I these

signals penetrate into audio lines, with su icient in-

tensity, can surpass the action o the special pro-

tection ilters, and to reach some sensible part o

the input stages. In that case, the inter ering sig-

nals can be demodulated and already turned audio

signal, and will be ampli ied by the rest o the sys-

tem. It is undamental, there ore, to maintain the in-

ter erence within reduced margins. It is obtained

avoiding very long audio lines, with aerial sections

or that pass near o trans ormers or RF transmit-

ters. For protection against very high requencies is

advisable to use double shielded cables, guar-

antied by the manu acturer.

CROSSTALK is the reception o signals coming

rom other lines o audio. This, like all unwanted

noise, it can be supposed controlled when its level

is below the level o the system residual noise.

Then, all considerations mentioned or the case o

buzz are valid.

2.1.2 RF in erference (Hum)

D612 consoles have numerous internal protections

against RF ields, or the AM and FM broadcasting

band. When the transmission station is installed

correctly, there will be no inter erence problems,

still with FM equipment o 50 KW installed in the

terrace o the radio station. Nevertheless, when the

antenna is badly positioned with respect to the Stu-

dio or has severe SWR problems, then it does not

have the minimum value o ield intensity, down-

ward. Or maybe there is a aulty ground connec-

tion, then, strong standing waves will appear on

the cables o the Studio that can induce high elec-

trical currents inside the audio console.

Symp oms: I the inter erence takes place at the

A.M. band, the sound transmitted by the A.M. radio

will be listened in the loudspeakers on background

(or at buses PGM, REC). In case o FM transmis-

sions, the inter erence inside the console demodu-

lates the A.M component o the FM carrier; (usually

hum rom power supply) causing background hum-

ming, because in many transmitters o FM, the inal

output stage is not powered with stabilized tension.

There ore, i console D612 presents humming,

please make a test shutting down the transmitter a

ew seconds to check i the problem disappears.

Sometimes, an FM transmitter with the output stage

badly calibrated also produce inter erence in which

you can hear the transmitted audio (due to the mis-

alignment a part o the FM modulation is translated

to AM modulation).

Solu ion: D612 consoles have internal ilters

against RF inter erence. There ore, i inter erence’s

appears, normally is caused by installation problems

on the transmission station that generate elevated

currents in the wiring o audio on the Studies, due to

the standing waves. These currents circulates inside

the cabinet o the console, and inter eres to the cir-

cuits when overpass the barriers that impose to this

Page 7 www.SolidynePro.com

currents the built-in RF ilters. The solution, then,

must be external to the console.

To solve it, pass all cables

through ferri e O-rings o 2”

diameter. They will be used in

each connector, o input and

outputs. The total set o cables that goes to each

connector, will have to be twisted around the ring.

2.2 Power source

At the le t side o the rear panel you will ind the

connector or the power supply. The switching

power supply (provided with the unit) works with

any AC network (90-240 V) and tolerate great

variations o tension. Gives regula ed 28VCC.

PLE A S E DON ’ T R EPL A C E T HE O R I GINA L

POW E R SUP P L Y.

The console doesn't have on/o switch. It remains

ed while the power supply is connected.

The grounding made through a bronze tip lo-

cated in the rear panel that provides the ground

connection to the chassis. Use cable o 2mm to a

good buried cooper bar.

2.3 Inpu channels

On the rear panel are located all the inputs and

outputs connectors. Take in mind that good connec-

tions o er sa e and ree o aults operation. By this rea-

son we recommend you: take it the time necessary to

make the connections care ully and use always mate-

rial o irst quality.

2.3.1 LINE inpu s

Each line channel has two stereo inputs, selected

rom the rontal panel. ‘BAL-1' and 'BAL-2' inputs

are symmetrical balanced, available at DIN con-

nectors. 'LIN-1' and 'LIN-2' inputs are unbalanced,

and uses Phono-RCA connectors.

To connect an equipment with balanced output you

will need a cable rom DIN-5 to two CANNON

(XLR) or stereo Plug’s (TRS ¼”) according to cor-

responds. The pin distribution o DIN-5 and XLR

are described next. Remember that you need to

connect TWO XLR to the DIN (balanced le t and

balanced right).

DIN 5 (s ereo bal.) Female XLR

1 AUDIO (-) RIGHT 1GND (shield)

2 GND (shield) 2AUDIO (+)

3 AUDIO (-) LEFT 3AUDIO (-)

4 AUDIO (+) RIGHT

5 AUDIO (+) LEFT

Unbalanced lines manages signals o -10dBV @

10KOhms (home type or semi-pro).

The GAIN con rol is common for bo h inpu s; ha

is o say, ha opera es on he selec ed inpu s.

2.3.2 USB audio in erface

The Channel-5 is or direct con-

nection to the computer using an

USB port.

Standard cable USB A/B are

used. Ports 1.1 or 2.0 are sup-

ported. Place the CPU so next to the console as it

will be possible, in order to use a wire o 2 to 3

meters o length. USB extension can be used; but

it is recommended no o exceed 4 me ers.

The channel must be connected to a computer

running Windows©7/10; Linux or OSX. When con-

necting the channel to the PC, Windows© auto-

matically recognizes it and installs the correspon-

dent drivers. Additional drivers are not required.

Be ore connecting the USB cable, make sure the

computer has e ectively grounded through its

terminal on the rear panel.

I you want to check the ground, connect a tester

on the scale o 25 Vac between the chassis o the

PC and console, and veri y that the voltage is zero

volts (+ / - 5V). Only then connect the USB.

I the equipment is not properly grounded, could

damage the USB port on the console or computer.

Windows© detect the USB channel as “USB au-

dio device”. At the console; the display indicator

“Digital In/Out” will show “U4”, indicating that

stereo input and output o USB channel was rec-

ognized.

www.SolidynePro.com Page 8

Remember that you can see the playing and

recording devices rom “Control Panel > Audio

and sound Devices > Audio”. In this window you

de ine the pre erred devices or Windows (those

that applications use by de ault). This is simple

since the devices are selected rom a drop-down

menu.

Con igure the USB devices in the automation and

editing so tware. I the computer does not have in-

stalled a soundcard, de ault playing and recording

device will be the USB device (Channel-5 input

and PGM or REC output).

In addition to the input, USB o ers a digi al send

o he compu er, that appears in Windows© as

“USB recording device” (PGM or REC). So that

you have available in the computer, the program

or recording signal.

ABOUT USB DETECTION

Window 7: Check if Window ha properly recognized

the recording device. If Windows recognizes the device

wrongly as “microphone device”, the recording will be mono

(same signal in both channels). To fix it, go to: Control Pannel

→ Sound → Recording → and choose USB device (appears

as USB microphone). Press [Properties]. Then select 'Ad-

vanced Options', open the drop-down menu Recording format

and choose stereo ( channels, 16 bits, 44.1KHz).

2.3.3 MICROPHONE INPUTS

Microphone channels are balanced electronically,

with XLR standard connectors.

Each channel has two XLR connectors that are

added internally. I two microphones to the same

channel, agrees that these are dynamic type, the

same make and model. Level di erences in the

voices are balanced by the audio compressor con-

sole. The action o the compressor depends on the

level o the PGM signal and is indicated on the

console.

The"48V"phantom power is available only or the

channels MIC-1a and MIC-2a. Remember that i

by mistake a dynamic MIC receives 48V, there is

no possibility o damage because its coil has ree

loating decouples this tension.

2.4 AUDIO OUTPUTS

2.4.1 PROGRAM AND RECORDINGS

Program ou pu (PGM) is the main output that

takes the signal that will be emitted to the air. It is

balanced, with emale TRS connectors (a.k.a.

“jack” ¼”).

Recording ou pu (REC) is balanced with Phono-

RCA connectors.

In order to connect PGM outputs to an unbalance

input, connect

only he (+)

pin, and leaving uncon-

nected the (-) pin.

To connect the balanced TRS output to a balanced

XLR input, the cable will be:

Balan ed onne tion Plug to male XLR

(for each channel

TRS (Plug XLR (Cannon

GND = sleeve

signal (+ = tip

signal (- = ring

GND = pin 1

signal (+ = pin 2

signal (- = pin 3

Please do not connect pin or pin 3 to ground. Never

uses “mono plug' s” (TS) to connect this outputs.

The nominal ou pu level is +4 dBu @ 0VU. I

you unbalance the outputs, take in mind that the

level reduces in 6 dB, there ore 0VU = -2dBm.

Note that i some nonpro essional equipment is

connected to the balanced output, may the level be

too high, causing saturation. In those cases a ixed

attenuation must be used to reduce the level (a re-

sistive splitter is a good solution).

2.4.2 USB send

USB allows direct connection with a computer, and

gives PROGRAM or REC signal (it switches rom

“USB OUT” in Channel-5). This eature don't re-

quires special drivers. Windows automatically rec-

ognizes the USB device (see “2.2.2.2 – USB).

Usually USB signal will be used or direct to hard

disk recordings; or webcasting. For details o use

the USB outputs in Windows© please see “3.6 -

Recording o programs”.

Page 9 www.SolidynePro.com

2.4.3 MONITORING OUTPUTS

2.4.3.1 HEADPHONES

There are outputs or STUDIO and Control Room

headphones. A unique knob manages the level o

the headphone and speakers outputs.

At the Studio, usually is used a headphone's mixer

like the Solidyne Studio-box (not included) to dis-

tribute the signal to each people. See “Chapter 5 –

Studio Box” or details.

2.4.3.2 MONITOR SPEAKERS

D612 was designed to work with active loudspeak-

ers. The STUDIO

and CONTROL outputs work with

line level at 0 dBu (0,775 V RMS). They have inde-

pendent controls or bus assignment and level. Both

outputs use emale 1/8” TRS connectors.

Remember that studio monitors are muted when mics

are on-air. Control Room speakers are muted when

the button Talkback is pressed.

2.5 Tally ligh

Tally light output gives 12V/120 mA when MICs

are turned on rom the Master Mic button. This out-

put supports the connection o two standard Soli-

dyne “on-air” tally lights.

NEVER exced 120 mA consump ion on Tally ou pu

The console has a built-in light; that resolves the on-

air signalization or small studios.

2.6 Telephonic Hybrid

2.6.1 CONNECTING A STANDARD LINE

The hybrid channel manages ONE land telephone

lines and ONE cellular phone. The internal adjust-

ments are rom actory; so the user do not needs to

make adjustments. Only the null- actor must be ad-

justed or the land line, only once on setup.

On the rear panel there are two RJ11 connectors;

or the telephone lines and the associated phone

set. The line can directly be connected to public

central telephone or the local central (PBX) o the

radio station. The private central sometimes deteri-

orates the hybrid rejection, reason why we advised

to directly connect the console to the public line,

whenever it is possible.

The telephone lines internally are protected against

lightings by metallic oxide varistors (SIOV). Never-

theless, we recommend to use additionally external

line protection o good quality.

Although the console has internal protection; it is recom-

mended to use external line a protection against tran-

sient voltage peaks due to accidents or lightings.

2.6.1.1 Null-fac or

This adjustment is only or LAND lines. The rejec-

tion actor expresses the capacity o the hybrid to

avoid that the transmitted signal returns distorted

to the air. Whichever greater it’s this actor more

“clean” will be the sound quality o the local

speaker on the air. In order set the rejection, pro-

ceed as ollowing:

Make a calling through one

hybrid o the con-

sole.

Ask a speaker to talk into the

microphone to the interviewee. Increase the

level rom "Telephone Control" until the voice

o the interviewee move the PGM VU meter

into the red zone.

Listening to the voice o the local speaker on

main monitors, turns the preset “Null” until re-

ducing to zero the distortion superposed to

the speaker’s voice. Please make this adjust

when the console is installed.

In case that the phone line connected to

the console be changed, this adjustment

must be repeated.

2.6.2 CONNECTING A CELL PHONE

It requires a phone with Bluetooth connectivity. Any

phone with Bluetooth can be linked to Solidyne

D612, eliminating the dependency on the adapter

cable "hands- ree". While the phone can be up to

10 meters away rom the console, you should

www.SolidynePro.com Page 10

leave it near, but not on the console. The

procedure to link the phone to the console is

similar to that used or other Bluetooth devices.

By linking your cell phone to the console creates a

link between the two devices, and allows the

phone to store the ID o the console. This

operation is per ormed only once ( or one cell).

Once the console and phone are connected, the

console automatically connects to the phone when

the Bluetooth link is enabled on both devices.

Procedure:

1. A he console, Make sure that the LED o

“Cellular Phone Bluetooth” is o . When Blue-

tooth is on, the LED “Cellular Phone Bluetooth”

lash in blue slowly (one lash every 2 sec-

onds). In this case, turn o Bluetooth pressing

and holding until the lashing button turn o .

1. A he console, enable the “discovery” mode.

This mode only can be accessed i Bluettoth is

turned o . Being the Bluetooth turned o ,

press and hold by 10 seconds the button “Cel-

lular Phone Bluetooth”, until the LED ast blinks

in blue-red. It indicates that the console is in

“Discovery” mode, to be recognized by by the

cell phone.

2. A he cell-phone: start a search or a Blue-

tooth device. This procedure can vary accord-

ing to the brand and model o cell phone.

Please re ers to the cellphone users manual.

3. When the searching ends, look or the D612

Bluetooth device, which will appear as Soli-

dyne BTM641. I the cell phone ask or a

password, enter 0000 and con irm (see the

user’s manual o the cell phone).

4. The ID o the Solidyne D612 is now stored in

the cell phone. The devices are "paired", no

need to repeat this operation while using the

same phone. The Bluetooth indicator light on

the console switches to slow lashing,

indicating "Bluetooth is active".

On some phones you need to "connect" the new device

found to stay active. In others, the new device is

enabled after being detected.

2.6.2.1 Re-connec a paired mobile

To reconnect a cell phone, proceed as ollow:

1. Turn on the Bluetooth o the D612 by

pressing “Cellular Phone Bluetooth” until the

LED lights (5 secs aprox). The button will

lash slowly in blue.

2. Enable the Bluetooth at the cell phone.

When the cell phone notice that the

connection has been made you are ready to

operate. When you make or receive a call,

the audio is routed to the console.

In some phones the re-connection is not automatic. You need

to "connect" the new device found to stay active.

2.6.2.2 Se up he level

VERY IMPORTANT: A he cell phone, Blue-

oo h volume mus be adjus ed a maximum

level in order to obtain a good reception and to

sure the best signal to noise ratio.

Thi adju ting mu t be done with a real calling u -

ing Bluetooth. Usually, the volume of the phone's speaker

is independent of the volume of Bluetooth device. If you

change the phone's level without make a Bluetooth calling,

you will only be changing the volume for the phone's

speaker, not the Bluetooth level. To change the Bluetooth

level, make a call using the console (or a hands free headset)

and set the Bluetooth level to the maximum. This setting is

stored at the cell phone's memory. If you u e another cell

phone with the con ole, you need to et the Bluetooth

level again.

2.6.2.3 TURN OFF BLUETOOTH

To turn-o Bluetooth at the console, press and

hold “Cellular Phone Bluetooth” until LED o .

2.6.3 EXTERNAL HYBRID

D612 supports external hybrids using a ¼” TRS

send and re urn signals. “External Hybrid” sends

PGM signal through the “tip” and receives through

the “ring” (return or input to console).

Ext-Hyb output (Tip); Is the return rom micro-

phones rom the console and PGM to the phone

lines. This is a MIX-MINUS signal, and connects

to the input “return to phone lines” at the external

hybrid (audio input o the hybrid).

Ext-Hyb input (Ring); Is the input or the audio

that incomes rom the external hybrid. This signal

is mixed to PGM but not to MIX-MINUS signal.

This input connects to the audio output o the ex-

ternal hybrid.

The audio rom external hybrid is routed to

TELCO. The Hybrid level knob works in the same

way that with the lines connected directly to the

D612’s built-in hybrid.

CHAPTER 3 Operation

3.1 Overview

Solidyne D612 is an compact audio mixer de-

signed or small radios. You can see di erent ar-

eas in the console:

•Input channels.

•Hybrid controls.

•Monitoring and talk-back.

•CUE

•MIC EQ

•Audio compressors and USB

•VU-meters

The bus PGM is the main output, that generates the

mix that sent to the transmitter (or streaming).

The bus REC is a secondary mixing. Usually or

recordings.

The operator can listen any signal be ore send it on-

air; by pressing the CUE buttons.

Line channels will be on-air just opening the ader.

MIC channels are turned on rom Master MIC but-

ton. The switch “PGM/REC” assigns the output or

each channel to the on-the-air mixing (PGM) or/and

the recording output (REC).

Line channels have two inputs; which are selected

rom a switch located at the top o the panel.

•Channels MIC 1 and MIC 2 only manages mi-

crophone signal. The phantom 48V switch en-

ables the phantom power to MIC-1a and MIC-

2a inputs. Remember that all dynamic micro-

phones are designed to support 48V phan-

tom, so you can mix condenser with the dy-

namic microphones.

•The microphone channels can be routed

to the processing s age (4 bands EQ and

compressor) with independence.

•The analog line channels manage bal-

anced (BAL) and unbalanced (LINE) stereo

inputs.

•The digi al channels manage the USB

digital inputs (DIG) and one analogical

stereo inputs (LINE).

•Additionally; USB o ers direct recording to

Hard Disk rom PGM or REC.

The D612 turret contains LED’s VU-meters that

show the recording and program level (average

peak level) and the action o audio compressor.

3.1.1 Quick es

Next are described the basic procedures to veri y

the console wiring. In order to check that all is

working well, please ollows the next steps:

•Choose a signal source, like a microphone,

a CD player, etc. According to the source,

select in the channel the corresponden in-

pu (MIC-LINE or BAL-LIN). This can be the

irst cause o error (there is no signal be-

cause the mistaken input is assigned).

•Press CUE button in the channel in which

the signal is.

•Open the CUE ader in the MONITOR SEC-

TION. The audio will have listened in the

built-in loudspeaker.

To send on-air:

•Send the channel to PGM, so that the signal

is sent to the main output.

•Open the main ader until reach 0VU in pro-

gram VU-meter. The signal will be aired.

•The gain knob must adjust so that the nor-

mal work position o the main ader is -15

dB (gray zone). In some countries (like Eng-

land) the user pre ers to adjust the normal

level with the ader at maximum.

Hybrid channel

The hybrid section manages 1 s andard elephone

line, and 1 Blue oo h cell phone (see “2.6.2 Con-

necting a cell phone”) Both can be in simultaneous

con erence (see 3.2.3 – Conferences .

Its use is simple and error free due to its logic of se-

curity and automatic control. The following instruc-

tions explains different scenarios of use.

Page 13 www.SolidynePro.com

3.2.1 Opera ion

When a call incomes, a blue LED blinks with the 'ring'

cadence. The calling can be answered in two ways:

a) Using the telephone associated to that line

b) From the console, by pressing the

HOLD/AIR button. When doing it, the line is

taken and the LED stops blinking.

To answer the call rom the telephone (connected to

the RJ11 on the rear panel) pick up the phone and

proceed as in normal communication. To put the call

on the air, press the HOLD/AIR button and then hang

up the phone.

To answer the call directly rom the console, press

HOLD/AIR. The console picks up the line and the

ring's pilot light turns o .

In this condition, the caller receives the program

signal, and will be on-air i the 'AIR LEVEL' knob

opens. There ore it is important to check that the 'AIR

LEVEL' knob be closed when take the line.

To talk privately with the caller, press CUE. The caller

is lietened on CUE speaker. In this condition (cue

pressed) the caller not hear the program signal. To

talk, press TALKBACK and use the talck-back MIC.

To pu he call on he air:

•Release the button CUE.

•Turn the control 'AIR LEVEL' until reach

the apropiate level.

The appropiate level or the communication is

adjusted by observing the level meter "PGM", but

also listening to the processed audio on the air.

To put the call o -air and resume in private, turn

down the knob “AIR LEVEL” and press CUE to

listen and Talkback to talk.

To ransfer he call o he phone se , close

"AIR LEVEL" to zero, pick up the phone and then

release the “HOLD/AIR” button on the console. I

the telephone was hung up when release the

HOLD/AIR, the communication will lost.

To hang up he line, turn AIR LEVEL to zero and

release "HOLD/AIR".

3.2.2 Using a cell phone

The cell phone connects to the Solidyne D612 via

Bluetooth. The irst time that a cell phone is used

with the console, it must be paired as explained at

"2.6.2 - Connecting a cell phone".

Once paired, the procedure used or the connec-

tion every time is simple:

•Make sure that the control “AIR LEVEL” is

closed, and the button CUE pressed.

•Turn ON Bluetooth at the console. For this,

press and hold “CELLULAR PHONE BLUE-

TOOTH” by 2 seconds (approximate) and

release when the green LED (located in the

VU meter panel) lashes. The LED remains

lashing slowly indicating that Bluetooth is

enabled.

•Turn on Bluetooth at the cell phone. I the

cell phone was already paired, in ew sec-

onds the connection reestablishes and the

cell phone stays linked with the console. Un-

der this condition, incoming calls are trans-

erred directly to console.

I the console is used exclusively with cellphone,

ie, there is little or no use o the land line, you

should leave the cellphone connected to the con-

sole and handle the calls rom the hybrid.

When there is a continuous use o both lines, ei-

ther alternately or simultaneously (con erence)

raises some peculiarities in the operation, de-

tailed in "3.2.3 Con erences".

3.2.2.1 Incoming call

Is explained bellow the use o a cell phone in per-

manent link to the console. In this condition, the

procedure to put a calling on-the-air is similar to

the seen or land lines:

•When a call incomes, the 'ringing' is listened

simultaneously on the telephone and on the

CUE speaker o the console (CUE button

pressed)

•Check or “AIR LEVEL”. It must be zero.

•To answer; make a ast touch on the button

“CELLULAR PHONE BLUETOOTH” o the

console (the calling can be answerer too

rom the cellphone).

A ter answering the call, talk to the caller, always us-

ing the hybrid o the console as ollows:

•With the button CUE pressed the caller is

listened on CUE speaker. Under this condi-

tion, PGM send to the cell phone is muted.

•Press and hold TALKBACK to talk with the

caller.

•When CUE is released, the caller will listen

to the PGM signal, but remains o -air due

to the control “AIR LEVEL” stays closed.

•To put the calling on-the-air, turn up “AIR

LEVEL” until reach the appropriate level on

VU meters.

www.SolidynePro.com Page 14

3.2.2.2 End he call

Pressing with short touch the "CELLULAR PHONE

BLUETOOTH" button on the console, communica-

tion ends. It is also possible to end the call rom the

cell phone screen.

3.2.2.3 Resume he call on he cell phone

To resume the call on cell phone; rom the phone

menu exit "Headset" (or Bluetooth) mode and

switch to the "speaker" mode (Speaker).

To trans er the call back to the console, return to

the "Headset" mode. This operation di ers de-

pending on brand and model o cell phone.

Below shows a screenshot o a cell phone with An-

droid, in the case o Bluetooth enabled.

The example shows the "Headset" icon, which

trans ers the call to Bluetooth device when it is

powered on; and passes the phone when it is o .

Other phone models can display two buttons; a

button with dropdown options; or other combina-

tions. Re er to the cell phone user manual.

3.2.2.4 Make a call

To make the call using the cell phone:

•In the cell phone, change the "Bluetooth"

mode to "Headset" mode as explained in

"3.2.2.3 - Resume call on cell phone."

•Dial the number in the cell phone and call

(SEND).

•To trans er the call to the console, return to

the Bluetooth mode on the cell phone (see

"3.2.2.3 - Resume call on cell phone").

•Release the CUE button on the console.

The cell phone receives the program signal,

but remains o the air i "AIR LEVEL" is

zero.

•To put the calling on the air, turn "AIR

LEVEL" to the correct volume.

•To end the call rom the console, make a

short tap the "CELLULAR PHONE

BLUETOOTH" button. The call can also be

terminated rom the mobile phone.

NOTE

The calling can be do rom cell phone without leave the Blue-

tooth mode, using the console's talkback circuit.

•The ring tone and the voice o the caller are listened on

CUE speaker (button CUE pressed).

•To dialogue, use the button Talkback o D-816.

•To hold the call, release the button CUE.

•To put the calling on-air, release “AIR LEVEL”

•To end the call, make a short tap on “CELLULAR PHONE

BLUETOOTH” button o the hybrid; or can hang-up rom

the cell phone screen.

Blue oo h advan ages

Besides the convenience o being able to connect

any cell phone without cables or special

connectors, provides the advantage o placing up

to 8 meters away, or example in a window to get

the best reception.

But also enables new operational advantages or

journalism, it is possible to connect the console in

seconds with the private cell journalist or stories to

people whose phone number is con idential and

the reporter did not want to reveal (very common

circumstance as journalists should be reserved

with your contacts).

3.2.3 Conferences

When regularly using cell phone simultaneously

with the landline, the user must be care ul to OFF

'BLUETOOTH' ON CELL PHONE whenever a call

ends. This way, i a new call comes while the land-

line is on the air, the call rings at the telephone. I

Bluetooth were active, the call would sound on air.

The procedure or setting a con erence depends

on which o the two lines (landline or cell) is on the

air. See the two cases below:

Page 15 www.SolidynePro.com

3.2.3.1 Being he cell phone on-air

Suppose the announcer is talking with a caller via

cell phone; and the operator requires adding to

someone else to the conversation:

•

Make (or receive) the call using the tele-

phone associated with the landline.

•

Talk with the caller. Warn him that the call

will go directly to the air. Remember that this

is because the hybrid is being used by a cell

phone, so operator can not put the second

line on hold or use the talk-back circuit.

•

Press "HOLD/AIR" to put the calling on-air,

then hang up the telephone. The call goes

immediately on-air (since "AIR LEVEL" is

open).

3.2.3.2 Being he landline on-air

Suppose the announcer is talking with a caller via

landline; and the operator requires adding to

someone else to the conversation:

•When is not used, Blue oo h mus be off

a he cell phone, and so unlinked rom

the console. This way an incoming call (or

is made) arrives to the cell phone with in-

dependence rom the console.

•To trans er the call to the console, urn on

he Blue oo h on he cell phone (see the

cell phone user manual). Depending on

brand and model o cell phone, the con-

nection with the console can be immedi-

ately re-established; or it may be neces-

sary to select rom a menu 'Bluetooth de-

vices' one to re-connect (in this case Soli-

dyne BTM641) Once activated Bluetooth

at cell phone, the call is put on-air immedi-

ately, staying in con erence with the land-

line that is on-air at this time.

•To end the cell phone call, hang up rom

the cell phone.

•Then, turn o Bluetooth at cell phone. This

is only necessary when there are a perma-

nent use o the landline, to avoid that an

incoming call to the cell phone acciden-

tally appears on-air when the landline is

on-air.

•Alternatively, to resume he call on cell

phone; using the cell phone menu it will

switch to "Headset" mode, as explained in

"3.2.2.3 Resuming the call on the phone"

3.2.4 Send PGM signal o he phone

The internal built-in hybrids dont’n have a level

control or the signal sent to phone line (aka “re-

turn” rom the point o view o the remote caller).

This is because the signal sent to phone line is

processed by AGC, peak limiter and ilters. There-

ore the send level is automatically adjusted during

the transmission and its level is the maximum al-

lowed by the modern digital telephone exchanges.

To check the send level to phone line, use an oscil-

loscope in parallel with the phone line and veri y

that the signal level is 2V peak to peak. Levels

over this value can cause like intermodulation dis-

tortion in the PGM signal.

For this reason the Solidyne hybrids use a pro-

cessed return channel, to avoid distortion at the

on-air signal. T

he send signal is limited to 400 –

2.200 Hz in order not to distort the signal on the

air. This narrow band intelligibility remains high

(due to processing) but occasionally may seem to

the remote people that it "has little volume" be-

cause the band is narrow. This should not worry

because it is a subjective sensation that does not

a ect the intelligibility o speech.

3.3 Moni or sec ion

3.3.1 Using moni ors and headphones

At the monitors section you can observe the ol-

lowing areas:

•

Studio Monitor:

here you define what sig-

nal

you will listen at the Studio monitors

and headphones.

•

Control Room Monitor:

define what sig-

nal

you will listen at the Control Room

monitors and headphones.

•

CUE:

set the CUE level

the built-in loud-

speaker.

There is a knob to manages the level o head-

phones and monitor outputs or the Studio. Usu-

ally the monitoring level adjusts rom the console

or a com ortable listening in the headphones. I

needs individual level control or each head-

phone; a headphones mixer (Solidyne Studio-box

or similar) can be used.

The S udio speaker moni ors have their own

gain control, since the console’s output was de-

signed to operate with powered speakers. When

the microphones are on-air studio monitors are

muted, to avoid eedbacks loops.

Like the Studio section, the Control Room has a

unique knob or the headphone and the speakers.

The Control Room monitors must be powered

units (active speakers).

www.SolidynePro.com Page 16

Routing switches allows to choose the signal

source or monitors and headphones. The assign-

ments or Studio and Control Room are indepen-

dent. The options are:

•PGM to listen the console output.

•REC to listen the channels that are as-

signed to recording output.

•AIR switches to an input designed to con-

nect an external tuner in order to moni-

toring the transmission from the air.

This is the right way for monitoring; rec-

ommended for all situations.

3.3.2 Use in o in egra ed S udios

There are many radio stations in which the

console, broadcasters and journalists are

located in the same room, avoiding the use o

double cabinet and glazing windows separator;

reducing the costs o construction and acoustic

treatment.

In this case, connect only one active speakers

to the output o Studio Monitor. This way, when

the microphones are on-the-air, the speakers

are muted. Also connect headphones to this

output o journalists and guests. Operator

headphones are connected instead to the

output o Control Monitor.

3.3.3 Previous lis ening (CUE)

The D612 has an internal loudspeaker or previous

listening. Each channel has a button “CUE” that al-

lows to listen the signal present in that channel

with the channel ader closed.

I CUE is pressed in several channels, the signals

are added. Rotary CUE level controls the volume

in loudspeaker CUE.

Additionally, signal CUE is sent to the control

room headphones. In this way the operator can

check the channels using headphones.

3.3.4 Talk back

The talk-back circuit allows the operator to talk with

the speaker while he is into the studio.

In order to talk, press the Talk-back button (see

monitor panel drawing) . The Control Room moni-

tors will be muted, to avoid eedbacks loops. Your

voice will be listened inside the Studio, by the le t

channel. The right channel stays with the on-air au-

dio, so that speakers and journalists do not lose

the On-Air re erence. At the same time talk-back

microphone will be listen in all studio headphones.

The operator can press CUE in a microphone

channel to engage in a dialog with the Studio.



The level of the talk-back microphone comes calibrated

from factory, and usually it is not necessary to modify it. If

you need to change it, there is a preset called “LEVEL”

to make the adjustment.

3.4 Microphone channels

3.4.1 Fea ures

There are two microphone channels. The “Phan-

om 48V” is common or both channels; but only

MIC-1a and MIC-2a gives phantom voltage. Re-

member that all dynamic microphones can connect

to a line with phantom voltage, without risk o dam-

age; because internally they have a trans ormer

that disconnects the DC. So it is possible to mix

dynamic and condenser microphones.

All the channels have a gain knob. It must adjust

so that the main ader works over the overload

“OVL” indication (- 30 dB). Remember that in all

audio consoles, excessive input gain reduces the

dynamic range. I you work with the main ader be-

low this level, the signal rom the previous stage

must be very high and the peaks will be clipped.

3.4.2 Processing

Each MIC channel can be sent directly to the air

(PGM) or the processing stage (EQ + compressor).

As well, the processed signal can be sent to the air

or to recording out.

Equalizer

The equalization settings are the same or all as-

signed channels. The igure shows the equalization

curves. These curves are designed to improve the

quality o the human voice. The ends o the spec-

trum work in shelving way, with 15 dB action.

As re erence we said that the LOW (or bass) con-

trol o ers “body” and “weight” to the voices;

whereas the HIGH one adds “presence” and usu-

ally improves the intelligibility. The central requen-

cies have a bell-shaped curve (peak EQ). Mid-bass

is centered in 160 Hertz, where usually the plop-

ping e ect are concentrated, or there is excessive

resonance in certain masculine voices. The mid-

high band is located at 5 KHz, because around this

requency usually appear the problems with the

“sss” (excessive emphasis the sibilants sounds,

like “shhh”)

Compression

The compressor maintains constant the peak level

o the human voice. It starts to work when the sig-

nal surpasses the 0 VU level. Below that level the

dynamic range is not a ected. D612 has a very

steep compression slope and ast attack and re-

covery times.

Indicator “MIC COMPRESSOR” shows in dB the

reduc ion applied to the signal.

Previous listening (Cue)

3.5 Line channels

Solidyne D612 mixer console has 3 stereo LINE

channels. LINE channels have two inputs that are

selected rom the ront panel.

•

Channels 3 and 4

have balanced stereo inputs

(DIN-5 connector) and unbalanced stereo inputs

(RCA).

•

Channel 5

are digital, with direct connection to the

PC via USB. It is equivalent to have an external

sound card. Additionally it gives one USB send to

the computer (PGM or REC). The secondary input

is analog unbalanced stereo (RCA).

LINE channels have gain

knob. For the case o USB

channels, there is not input

gain. Level adjusts rom Win-

dows audio mixer.

Set the input gains in order to

the main aders, with an nomi-

nal level at input, works al-

ways above the OVL zone, to

avoid overload.

Connections are explained at

“Chapter 2 – Installation and

wirings”

To put a channel on-the-air;

assign the channel to PGM

and open the ader. The cor-

rect level is when the peaks at

0VU continuously.

Main aders works with ETM-

VCA echnology (Electromet-

ric-Voltage Controlled Ampli-

ier). The ader only manages

DC, that control ampli ier with

variable gain.

This method guarantees very

low distortion and is noisly-

ree. For more in ormation

about the ceramic ader tech-

nology, please visit:

www.SolidynePro.com.

3.6 Recordings

D612 consoles have two stereo output channels.

The main channel is denominated Program (PGM)

and used or the On-Air signal.

For recordings, REC bus is used. The user can

make recordings while, simultaneously, the con-

sole is on the air. We will see like example the pro-

cedure to make a recording in the computer

whereas a musical program is on air.

NOTE: the two telephone hybrids o this console

are units "aired" and there ore can not be assigned

to the channel REC. I you need to record an

interview you should connect to the console a

hybrid external; Solidyne type HL-202.

Page 19 www.SolidynePro.com

3.6.1 Direc o Hard Disc recording

Remember that the main output (PGM) and the

recording output (REC) are available in digital or-

mat, through connections USB.

like: (Control Panel/Audio and Sound Devices/Au-

dio)

“USB Recording device”: cor-

responds to channel USB 5

and gives the PGM or REC

signal.

On the PC: configure your

recording sof ware to use

an USB recording device.

At the onsole: route the

channels that you want to

record to REC bus. The oth-

ers remain assigned to PGM. You must proceed as

ollows:

a) In Monitor Section assign the Control Room

monitors to the recording bus (REC). I you

want you can send REC signal to the studio

monitors too.

b) Assign to REC the channels required or

the recording ( or example MIC-1 and Line-

4). When a channel is routed to REC it is

removed rom Air

c) Meanwhile the radio still on air through, or

example, the channel 5 with a musical pro-

gram.

Channel-5 can be used for playing with independence

of the assignment to USB OUT (PGM - REC).

Now makes the recording on the PC. In order to

activate the microphone, open the ader o MIC-1

channel.

The recording level is veri ied in the REC VUmeter

o the recording so tware, and it adjusts rom the

console. You cannot change the input level rom

so tware (Windows Mixer).

USB RECORDING DEVICES DO NOT HAVE

GAIN CONTROL FROM THE SOFTWARE

The speakers will listen to the recording USING

HEADPHONES or in loudspeakers. When the

recording ends, it can be listened using the same

REC bus, assigning to REC the channel in which

the PC is. At this point; BE CAREFUL OF NOT

PRODUCING A FEEDBACK LOOP IN THE OWN

COMPUTER. MAKE SURE TO MUTE IN THE PC

(FROM WINDOWS MIXER) ALL SOURCES OF

SIGNAL EXCEPT “WAVE” AND “GAIN CON-

TROL” (MAIN).

When the work is inished, reset all the controls to

the original position, to return the console to the

normal way o operation.

3.6.2 Recording he phone lines

Hybrids o the D612 signal sent only to program,

there ore, only be recorded telephone

communications PGM signal recording.

To record the PGM output, you must use a wire tap

"Y" or a "copy" o the program output, simply

connecting two parallel cables.

“Y” cable - Plug 1/4" BAL to XLR BAL and unbal RCA, to one input

channel. For the other channel you need a second “Y” cable.
