FEATURES -
The Soli yne S-500 satisfies all the basic necessities of a ra io on-air stu y, obtaining excellent
cost/benefits relation. Unlike other consoles of low price, the S-500 has “ igital” au io quality. This unit
has been esigne specially for small an me ium ra ios that, in spite of counting on fewer resources,
wish to have equipment of first level in their stu ios. The S-500 offers to you the trustworthiness an
quality that characterize to the professional Soli yne equipment.
Brief description
Inputs
The S-500 console have 5 main fa ers of 4” length that manages: two microphone mo ules, with
balance inputs (Jacks ¼”) an 3 LINE mo ules with RCA connectors; two of them with balance inputs,
switche from the front panel of the console (Bal-1 an Bal-2). The fourth line is unbalance with an 1/8”
jack connector (Lin-4).
Mike modules have 4 bands EQ (+/- 15 B action); an an automatic audio compressor, which starts to
work when the signal surpasses the 0 VU. EQ an compressor can be bypasse in each mo ule.
An AIR input allows to connect an external AM/FM receiver to monitoring the on-air transmission.
Portable S-500/6M model: In this mo el, the line inputs are replace by microphone inputs, to obtain 6
microphone inputs. For etails refers to the Chapter IV.
Outputs
♦PROGRAM OUTPUT is use to sen the au io signal to the ‘air’. It’s a ¼” jacks balance output.
♦REC OUTPUT is use to recor ing a mo ule without sen it on-air. Is a balance out an is available
on the DB-15 connector.
Cue: Previous listening
Pressing a CUE button you can listen, even with the main fa er close , the signal present in this channel.
Pressing CUE again the operation is cancelle . The signal is listene through an built-in lou speaker,
locate on VU-panel. If button CUE is active in several mo ules, you will listen to the sum of the signals
present in each mo ule. The listening level a justs with the CUE LEVEL fa er, locate in the Master
mo ule.
VCA
Levels are controlle using VCA technology (Voltage Controlle Amplifier). With this technique, the au io
signal on’t circulates through the fa ers. The levels are controlle using electronic amplifiers of low noise
an great stability. The fa ers only manage DC that controls the amplifiers. The principal a vantages of
this technology are:
♦Eliminate noise an ‘crashes’ pro uce by irty or spent fa ers.
♦Eliminate the cleaning maintenance of the fa er.
♦Obtain a perfect stereo-tracking (< 0,1 B).

CHAPTER 1
-Installation
1.1 Connecting t e console
Although the S-500 is not a mo ular console, since it’s mounte on an unique printe boar , we will talk
about to the ifferent channels enominating them “mo ules”, by custom of use in other console mo els.
In spite of having an only circuit boar , the replacement of the main fa ers is simple, because these are
not wel e to the boar but that they are mounte to the chassis with screws.
All the I/O connectors are in the rear panel of the cabinet. Remember that a safe an free on faults
operation epen s of the wiring of the ifferent sources to the console, reason why we recommen you to
take the time necessary to make all connections with the greater care an always using material of high
quality. A goo solution is to acquire the complete cable set (kit Soli yne MNG-500).
1.1.1 Microp one modules
All microp one inputs are balance , with connectors Jack ¼” type. Remember that pins 1, 2 an 3 of the
XLR connector must be connecte to the Plug (TRS) to “sleeve”, “tip” an “ring” respectively, as showe in
1.3 – Connection general iagram.
P antom power source
The S-500 allows to activate a phantom power source which gives 9-12 VDC (between tip – ring). To use
mikes that operates with 48 V phantom, you must use an external power source. Please consult with your
Soli yne ealer to acquire external phantom’s; or contact us via e-mail.
¡Warning! Always use balance connections. Otherwise, hum an noise will can appear.
1.1.2 Line modules
There are 3 line modules. Each one has 2 stereo inputs, assignable from the front panel. Mo ules LIN-1
an LIN-2 can be switche between balance (DB-9) or unbalance (RCA) inputs. See Table-2 for
connection’s etails. LIN-3 mo ule can be switche to enter from an RCA input (LIN-3) or a minijack (1/8”)
calle LIN-4. This input is recommen e to connect a PC equippe with a non-professional soun car .
Each line mo ule has a gain control which affects both inputs. Gain controls compensate the input gain
for the ifferences of the sources, in or er to obtain a same output level for equal’s fa ers positions.
Following the actual engineer criteria, the input impe ance is bigger than 10 KOhms (Bri ging inputs). This
is a equate to all current equipment’s ( ecks, DAT, Au icom, Mini- isc, CD players, etc.) But if you nee
to a apt the impe ance to 600 Ohms, you must a a 680 Ohms resistor insi e the connector, in parallel
to the input.

1.2 Rear Panel
1.2.1 Power Source
The S-500 works with 28 VCC provi e by an external power source. At the left corner of the rear panel
is locate the power connector (tubular 2.1 mm). Always use the external power source provi e with the
console. Verify that the AC switch (220/110 V) is in the right position.
Warning! Connect the power source to the console first, and then to the AC line, in order to avoid sparks on the connector.
1.2.2 On-air signal (Tally)
On-air output is a tubular connector (2,5 mm internal pin) that gives 12 VDC/0.3A when a mike fa er is
opene . The output returns to 0 volts when the fa er is completely close .
On-air signal is use for activate a tally light which in icate to the speaker or journalist that the mikes are on-
air. A goo an professional solution is to acquire the Soli yne On-Air-Light kit: a soli state isplay of big
size. Other option is to use a Stop light use in the cars, or connect a relay to activate another type of light.
1.2.3 AUX OUT connector
The connector DB-15 AUX-OUT (auxiliary outputs) has several output signals:
REC output: Balance stereo output. Any mo ule can be assigne to the REC bus. Remember that when a
mo ule is assigne to the REC bus, it’s isconnecte from PGM bus, allows you to recor ing this channel
without to sen it on-air.
Unbalanced PGM output: gives the same signal that the main PGM output but unbalance . Usually is use
for recor ings. In Au icom systems this output is connect to an input of the PC to recor ing interviews,
shows, etc., eliminating the use of cassettes or mini- iscs.
Send PGM mono (for external ybrid): is use to connect an external hybri . The mix sent is “mix-minus”
with respect to the input Hybrid Return of the S-500, that is to say, the signal that returns from the external
hybri is a e irectly to the program output an therefore isn’t present on PGM sen .
External ybrid return: Here the output of the external hybri is connecte . This signal is sent irectly to
the PGM output. This input eactivates when you take the line from the console hybri s.
Note that the input ‘external hybrid return’ oesn’t have gain control. The level on the PGM mix will be
controlle from the output level control of the external unit.

1.2.5 Monitors & Headp ones outputs
CONTROL outputs are use to connect the monitor lou speakers (MON) an the operator’s hea phones
(PHONE).
STUDIO manages the monitors an hea phones for the stu y cabinet. In both cases the outputs presents
stereo minijack connectors (you can connect “multime ia PC speakers” irectly to this outputs).
To the monitor lou speakers outputs (MON) is convenient to use powere lou speakers, avoi ing the use of
a itional amplifiers. A PC powere lou speakers of goo quality will be sufficient for most of ra io stu ios,
being an low cost solution.
All outputs are protecte against acci ental short-circuits. Each hea phone output can manage up to 3
hea phones (in parallel).
Muting system
The output of the stu io’s lou speakers is muted when you open a mike fa er, to avoi signal loops. The
program signal an the talk-back or ers will be listene in one channel of the hea phone. As well, when
you pulse the talk-back button, the CONTROL lou speakers are mute to not interfere with the
microphone of or ers.
1.2.6 Telep one line connection
The built-in telephone hybri manages one telephone line. On the rear panel there are two connector RJ11
type: one for the telephone line an other for the associate phone. This phone works normally while the line
isn’t taken from the console. The phone line can come irectly from the public central telephone offices or a
ra io’s private central (PBX). The private centrals can eteriorate the hybri ’s reject factor, for what we
recommen you to connect the S-500 irectly to the public telephone central.
Hybri ’s inputs have internal filters to reject RF, for the mi -waves (AM) an for VHF an UHF, not being
necessary, usually, a a itional filters.
The level a justments for sen , return an reject factor are calibrate in factory an generally a itional
a justments aren’t necessaries. Nevertheless, in case that the voice of the local speaker was altere in its
quality when making a telephone conversation, the control of balance of the Hybri will have to be rea juste .
This is ma e uring a telephone conversation, using a very small screw river to a just a preset locate below
the hybri ’s activation button. It will have to be turne in one or another sense until obtaining that the voice of
the speaker of the ra io soun s natural, with the same quality that when the Hybri is isconnecte .
Telephone lines must have protection against overshoots espite to acci ents or electric storms.
1.2.7 Using an external ybrid
The S-500 console is esigne to connect an external telephone hybri , necessary when it’s require to
manage two or more lines. To it, it is arrange in connector AUX-OUT a Program Sen (mono) that will be
connecte to the au io input of the external hybri . The output of the hybri enters through a special input
enominate Hybri Return of the same connector (see Tabla-1). This input is MIX-MINUS respect to PGM
Sen , that is to say, the Hybri ’s Return signal is a e irectly to the program out but he is not present in
PGM Sen , not to pro uce a fee back loop. The Hybri ’s Return input is eactivate if the line is taken from
the S-500 built-in hybri . The fa er SEND only works with the internal hybri . There isn’t level control for the
signal that enters by Hybri ’s Return. You will have to use the output level control of the external hybri .

CHAPTER 2
- Operation -
2.1 Introduction
The au io signals originating of the computer (Au icom); Microphones, Satellites; CD players; etc.; they
enter the console through the input channels, that amplify them. The signals of these channels are sent to
PGM output (signal sent to the air) or REC output (for internal recor ing), that are both ways that can cross
the signal towar s the output connectors.
MICROPHONE mo ules receive the balance signal through a stereo Jack (¼”).
LINE mo ules can receive signal from two stereo sources:
LIN 1 an LIN 2: commutable between unbalance (RCA) or balance (DB-9 connector) input.
LIN 3: commutable between unbalance RCA or unbalance Minijack (LIN-4).
The commutation between inputs is ma e from a switch in the front of the mo ule. A secon switch allows
you to assign each mo ule to the outputs PGM or REC.
The VU-meter panel has two vu-meters LED type, for PGM an REC. The action of the au io compressor
(mike mo ules) is in icate by a LED-bar; an a square re LED in icates when the built-in hybri takes
the telephone line.
The MONITORING SECTION, locate below the vu-meters, contents the fa ers that manage the
monitoring an hybri ‘on-air’. Below the vu-meters you will fin the talk-back section an the CUE
lou speaker.
2.1.1 Starting up
Connect any signal source to a LINE mo ule, e.g. a CD player, an a couple of powere lou speakers to
the CONTROL MON output. Also a microphone can be use , to prove the behavior of the EQ an the
compressor. To route a signal that enters a mo ule to the PGM output (on-air), follow the following steps:
a) Select the correspon ent input, where you have connecte the CD player (RCA, DB9, mini-jack),
using LIN-1/BAL-1 or LIN-3/LIN-4 buttons, accor ing to the mo ule use .
b) Assign PGM/REC to the output "PGM".
b) Verify that the signal is present pressing the CUE button. The au io signal shoul be listene on the
built-in CUE lou speaker.
c) Pick up the fa er, the signal shoul be showe on vu-meters.
d) If you on’t hear the au io, verify on the monitoring section the position of the switches. Both must be
at the right, that is to say, STUDIO MONITOR in the position PGM; an CONTROL MONITOR in the
position STUDIO MONITOR.

positione in this area gives

2.2.1 Equalizer
The EQ acts on both microphone channels, but you can bypass it on each channel with the switch
EQ/PGM (which acts also on the compressor).
♦In EQ position, the signal is route through the EQ an the compressor.
♦In PGM position the signal is sent irectly to the program output.
The switch OUT PGM / REC allows you to sen the processe signal to the PGM or REC bus output.
EQ ban s are: 80 Hz, 160 Hz, 5 KHz y 10 KHz. They can be change in a range of +/- 15 B. The central
ban s are bell-shape type, whereas 80 Hz an 10 KHz ban s are shelving type.
When the switch OUT PGM/REC is in REC position, there is not MIC signal at the PGM output, although the
EQ/PGM switch is in PGM position.
2.2.2 COMPRESSOR
The output of the EQ is sent to an automatic compressor, of very low istortion, esigne to re uce the
ynamic range of the signal ( ifference between the maximum an minimum level) without altering the
soun . This avoi s possible istortions by clipping (saturation), that take place when who speaks elevates
much the voice level, or too much approaches the microphone. This is essential for interviews in Stu y,
because it maintains the output level of the console very constant.
As was explaine , compressor an EQ stages are activate at the same time with the switch EQ/PGM.
Au io signal is compresse only when is over 0 VU. Below this level the compressor oesn’t works. When
this threshol is overpasses, the console re uces his gain to maintain constant the output level. By
example: if the mike signal increases abruptly 15 B over 0 VU, the increase at the output will be only of 2
B.
The actino of the compressor will be in icate by four LED’s which in icates the gain re uction. Obviously,
the vu-meters shows the level of the processe signal, that is to say, the real output level.
2.2.3 “P antom” power source
Phantom power source are use with microphones that requires external fee ing (con enser type). The S-
500 gives 9-12 V phantom tension. If you nee 48V phantom, you must use an external phantom power
source.
Remember: always respect the balance connections, since if the conections are efective an the phantom power
is active, it can pro uce amages or backgroun noise, even amages to the mike.
2.2.4 Gain adjustments
All mo ules have an overloa in ication (OVL) printe besi e the fa er. The rule is:
With signals at VU, the main fader must be positioned over the OVL indication
If the fa er is un er this in ication, the input will overloa an clip the signal. To obtain an optimums
a justment, open the fa er until the area of normal work (graye zone between 10 B an 20 B) an
a just the gain knob until reach peaks of 0 VU in the vu-meters.

2.4 Recordings
The S-500 has two stereo outputs. One is use to sen the signal on-air, calle Program (PGM). The
other one is enominate REC an typically is use for recor ings. All mo ules can be route to PGM or
to REC outputs, but not to both outputs simultaneously.
NOTE: When the onsole is used in a Produ tion Study, you must use the PGM output to send signal to audio
re orders, in order to be able for re ord the telephoni interviews, sin e the hybrid is routed only to PGM.
The signal of the built-in hybri is a e to the PGM output irectly, thence, to recor in the Air Stu y all
the emitte on-air, even the hybri , you will must to use the unbalance PGM output (connector AUX-
OUT).
To make a recor ing, select previously the source channels. By example: supposes that while a musical
program is on-air from a CD player, you want to recor a commercial cut from a mini- isc to har isk.
a) Select in the Monitoring Section the output bus ‘REC’, using the switch CONTROL MONITOR, to listen
only the signal that you will recor .
b) Switch the buttons PGM/REC to the position “REC” in the mini- isc’s mo ule. Remember that the au io
on’t be on-air, it will be sent only to the PC through the output REC. To check it, change the position of
the CONTROL MONITOR switch.
Now, you can start the recor ing on the PC. The recor ing output level is showe by the REC vu-meter of
the S-500. When the recor ing en s; leave all the controls to their normal position.
2.5 Monitoring, ybrid and vu-meters
2.5.1 Monitoring section
This control manages the level of the signals sent to the Stu io
(STUDIO CONTROL) an the Control Room (CONTROL
MONITOR). In both cases, an unique knob manages the level
for hea phones an monitor lou speakers. This simplifie
esign was evelope to use the S-500 with active speakers
that have their own level control, by means of which it a justs
to the relation of levels between the hea phones an the
lou speakers.
AIR/PGM switch allows to monitoring the on-air signal from
console output or to listen the real transmission from air, using
an external receiver connecte to the AIR input (rear panel).
This signal sen s to the Stu io. In the Control Room, the
operator can listen the on-air signal irectly from PGM output
or from the air, accor ing to the AIR/PGM status, or to listen
the REC output.
2.5.2 Previous listening (CUE)
Pressing the CUE button at any input mo ule, the au io will be listene on the built-in CUE lou speaker,
even when the main fa er is close . The volume for the CUE speaker controls with the CUE LEVEL knob.
You can press two or more CUE buttons at the same time to cueing several signals.
SOLIDYNE Consolas serie S-500 page 13

2.5.3 Talk-back
To sen or ers to the Stu y, press an hol the Talk-back button. To speak irecting the voice towar s
the microphone; it is not necessary to approach too much. Program au io repro uce by the Control
Room monitors it will be mute to avoi fee back loops an will be listen the operator’s voice in the Stu y
through the lou speakers. If these were mute (MIC fa er open); the or ers will not be listene in
lou speakers. They only will be listene by hea phones. In both cases, the or ers will be listene on the
left channel, while in the other channel the program signal stays for reference.
In or er to engage in a ialog with the speaker, press CUE in the microphone mo ule. Must special well-
taken care of with the CUE level to avoi fee backs with the microphone of or ers.
2.5.4 VU-meters
The main VU-meters is stereo an correspon s to the PGM bus. The scale is expresse in Bm,
in icating the level of the balance PGM output.
A secon ary mono vu-meter shows the REC level, a ing the L&R channels.
The compressor action is in icate by a LED’s bar (MIC COMP) that lights in icating the attenuation
applie to the signal.
LED HYBRID lights when the telephone line is taken in the console.
2.5.5 Operation of t e telep onic Hybrid
The operation of the hybri is very simple. The calls are establishe from the associate telephone, or that
the call becomes from that telephone that is an incoming call. When you want to put the telephone on-air,
verify that fa er SEND is close an to take the line in the console pressing button TELEPHONE HYBRID.
A re LED will light in the vu-meters panel in icating that the line is taken. Hang up the associate
telephone. In this con ition, the person who is waiting receives the program signal, that is to say, they will
listen the ra io through the telephone. If once taken the line you wish to return to speak with the caller, you
can pick up the telephone an speak normally, even maintaining taken the line in the console.
To put t e call on-air: open fa er SEND until reaching a correct level, measure in the PGM vu-meters.
In or er to quit the line of the air, close the fa er an then release the button. Not cut the communications
irectly from the button because can cause a ‘plop' on-air. If you wishes to quit the line of the air but to
maintain a communication, pick up the associate phone before releasing the line in the console. The call
will have left erivative to the phone again.

CHAPTER 3
-Maintenance -
In or er to obtain from the S-500 console the excellent benefits that Soli yne guarantees with its esign
an manufacture, we recommen e to follow the in icate operative proce ures of this manual.
3.1 Cleaning
The front of the mo ules an the cabinet in general will be cleane using a very smooth etergent (of the
type use for painte walls or papering) an a sponge or fine cloth. DON’ T USE alco ol, benzene
neit er ot er derivatives of petroleum.
Avoi the ust accumulation on the equipment. Don’t smoke while operates the console, the cigarette
also is injurious for au io consoles, since the ash accumulation in the fa ers re uces its life utility
remarkably.
The main fa ers are of high quality, Polishe Coal type. They manages only DC an its uration, in normal
con itions of operation, excee s a million operations.
3.2 Spare parts
In or er to change a fa er it’s not necessary to disassemble t e entire console. It will be enough to
remove the base of the S-500, by quitting the 9 screws. The fa ers are accessible since are not wel e to
the circuit boar . To retire each fa er simply quit both screws that hol it to the panel an to wel the new
unit. The spare part of switches or buttons is ma e removing the knobs from the console an retiring the
printe boar , relaxing the screws that hol it.
KIT OF SPARE PARTS (Co e SPARE500): Kit of general spare parts for the console can be acquire ,
which inclu es integrate circuit, transistors, LED's, buttons, switches an fa ers.
NOTE : The Service Manual, with inclu es schematics an components istribution iagrams, is sent without
charge to fully qualifie technical personal who approves the Soli yne training curses

CHAPTER 4
Portable console S-500/6M
In this mo el the balance LINE inputs become balance MICROPHONE inputs. Unbalance inputs (RCA
connectors) remain without changes. The istribution of microphones in the S-500/6M is the following one:
•MIC 1 an MIC 2 in channels 1 an 2. Like in the stan ar mo el, microphone’s mo ules can be route through
EQ an compressor. Each mike is sent to both stereo channels (L&R).
•MIC 3 an MIC 4 form a stereo pair (MIC 3 = L; MIC 4 = R) an are controlle with the Channel 3 fa er.
•MIC 5 an MIC 6 form a stereo pair like the previous case, controlle by the Channel 4 fa er.
The next iagram shows the connection between a S-500/6M an a laptop, to make a transmission via
Internet (streaming).
The console have outputs for CONTROL an STUDIO hea phones, with in epen ent level’s control (up to 2
hea phones in parallel by output). The Monitor output in the mo el 6M are always active, that is to say that
the microphones are not mute when opening.
SOLIDYNE Consolas serie S-500 page 17

When you operate connecte to the stu y by telephone line, you must select the mo e “PGM" for STUDIO
an CONTROL monitors. This form, the conversation generate in microphones (1, 2, 3 an 4) , 2, 3 an 4
as the return’s signal from the STUDIO of the RADIO, will be listene on the hea phones too.
If you nee to connect a secon console, they can be connecte though LINE of Channel 5.
If you want to monitor with lou speakers, you can use active speakers (like the use on the PC's) on the
STUDIO MON or CONTROL MON outputs. Take care with the istance between microphones an monitors,
to avoi fee back loops.
Positioning mikes in stereo
Take in min that the pairs of stereo microphones (3/4 an 5/6) must be locate to each other separate .
Example: in or er to take a piano from tail istances of 1 to 2 meters they are a vise . In or er to take a small
orchestra it agrees to separate between 2 an 3 meters the microphones of the stereo pair. In all the cases
the singers must be taken more close possible an with microphones 1 an 2.
An alternative technique to recor ing takes for big orchestras is to use “coinci ent microphones”. This
technique consists in to create the stereo image using irectional microphones (car ioi s). For it, their axes
mount in the same support crossing 90 egrees. This technique, enominate microphones BLUMLEIN, is
one of the favorites in Europe to take the orchestra an the environmental reverberation.
