Installation/Wiring/Operation
1.1 Console Placement
Because neither ventilation, or rear access is required, the console may be mounted on any sturdy surface. Opening
the lid provides access to all electronics, internal controls and wiring points.
After placing the console, open the lid and mark the cable access slots on the chassis bottom on the table surface.
Remove the console and cut the slots with a saber saw. The console may then be permanently mounted with two #10
sheet metal screws inserted through the two holes provided in the front of the chassis’ bottom.
1.2 Opening the Console
A “T”-shaped lifter is provided by the factory to open the console.
This lifter can be inserted in any fader slot, angled and used to raise the lid. Once the lid is opened, the two hinges are
pulled forward to lock the lid open.
To close the lid, push the hinges in to release the locks, while holding the lid up with the “T” lifter, and gently lower the
console.
The external lifter discourages unauthorized access to console electronics.
1.3 Power Supply
1.3.1 Installation
All console operating voltages are provided by the external power supply which connects to the console via a multi
conductor cable. A ten foot length is provided as standard equipment. Longer lengths, up to 20 feet, are available from
the factory.
To install the cable, remove the top cover of the power supply and insert the end of the cable with the large solder lug
through the rectangular cut out in the power supply back panel. Plug the connector into the circuit board and secure the
solder lug to the ground stud provided on the inside rear panel. After replacing the top cover, the supply may be hung
from the key-hold slots in the cover, placed on the shelf or the oor, or rack mounted with the optional rack adapter front
panel.
To connect the console end of the power supply cable, pass the other end of the cable (with the smaller ground lug)
through the rectangular hole on the center right-hand-side of the console base. Screw the ground lug under the mount-
ing screw on the right front hand side of the Output Board. Plug the 10 position connector into J24 and the 4 position
connector into J26(Ouput Board v.2: Plug the 10 position connector into J6 and the 4 position connector into J8).Take
extreme care to plug these connectors in with the correct orientation - locking tab to loacking tab (with cables existing
towards the right hand side) as it is possible to plug them in backwards.
A grounding stud is provided on the rear of the power supply. Console grounds reach a common point at the power sup-
ply. To minimize RFI and potential ground loop problems, the console should only be connected to station ground at this
one ground stud.
In intense RF environments, or if you experience any RFI problems, consult RFI suppression in the Troubleshooting and
Theory of Operation Section for detailed information.
1.3.2 Conguration
The power supply houses a switch-mode module and an interface and indicator board. This provides 15 volts for audio
circuitry and 7.5 for control circuits.
Front panel LED’s show the status of both 15 volt modules and the 7.5 voltages derived from the rst module. Fuse
holders are front panel mounted housing a 2 amp fuse for the rst module and a one amp fuse for the second.

Radio Systems Millenium-A Console Page 7
1.4 Wiring Access Layout
1.4.1 Connectors
Millenium Analog Consoles can be ordered with RJ-45 female connectors, pinned out to the StudioHub+ standard, or
with 5-pin removable barrier strip connectors (quick connector).
1.4.2 Inputs
All audio inputs and audio patch points wire to the Six Channel Audio Board(s) on the base of the console. One board is
utilized for every 6 channel positions. Audio inputs are stereo and balanced. The left and right channels of one input are
wired to a single connector. Interstage channel audio patch points are unbalanced. These loop-thru inputs and outputs
for each channel are accessible on a single 5 pin quick connector. On RJ-45 version consoles only, there is also a 3-pin
post-fader patch point.
Consult the Six Channel Audio Board Section of this manual for detailed information on input and patch point wiring and
level attenuation.
1.4.3 Outputs
All program outputs are balanced and appear on connectors on the Output Board.
Also mounted on this board are connectors for external monitor inputs, monitor sends, talk back, timer reset, cue audio,
and control sends.
Consult the Output Board Section of the manual for detailed information on output and control wiring and level calibra-
tions.
1.4.4 Control
The front panel mounted Six Channel Control Board houses one 15 pin D connector for each remote channel control.
Consult the Six Channel Control Board Section of this manual for detailed information on control remote functions and
programming options.
Consult the Interface Options and Accessories Section of this manual for detailed information on the optional interface
card applications, wiring and function.
1.4.5 Wiring Quick Connectors (5-Pin Connector Console Version)
Audio input and output connections to the console are made via 5-pin connectors. These connectors may be unplugged
from the circuit board to facilitate wiring or servicing.
StudioHub+ wiring harnesses are available from Radio Systems which bring all input and output connections to conve-
nient connection blocks outside the console. Consult the factory for literature.
1.4.6 Wiring RJ-45 Connectors (RJ-45 Connector Console Version)
Use standard TIA 568B RJ-45 STP patch cords or 22 AWG shielded wire for audio connections. The cable should be
stripped so that the insulation comes close to, but does not enter the connector.
StudioHub+ wiring harnesses are available from Radio Systems which bring all input and output connections to conve-
nient connection blocks outside the console. Consult the factory for literature.
1.5 Operation
The Millenium Consoles have been designed to offer the greatest combination of user exibility and operating ease. Ob-
viously, the console should be installed and operated in accordance with station format, personnel habits and engineer-
ing principles.
The following sections suggest some operational possibilities which were considered in the console design.

Radio Systems Millenium-A Console Page 8
1.5.1 Input Assignment
Traditionally, commonly used inputs are assigned to input “A”. This gives the operator quick assurance of proper input
selection.
1.5.2 Mic Use
Mic channels should always be activated with the slider down, and then potted up to avoid a sudden “room rush” of
background sound.
Cue speaker muting is only provided when a mixing channel is turned “on”. Therefore, feedback can occur between the
cue speaker or the monitor speakers (if cue monitoring is selected) and a mic input if the mic channel is placed in cue.
To avoid this possibility, remove the cue inhibit jumpers on the section of the Six Channel Control Board associated with
the mic channel. This will prevent a mic channel from entering the cue mode and possibly cuing feedback. Consult the
Six Channel Control Board Section for details on programming information.
1.5.3 Cue Circuitry
Unless disallowed by jumper removal, all selected inputs maybe placed on the cue bus by depressing the cue button,
located above the fader. Refer to Section 2.2 for additional information.
The cue signal is monitored by the cue speaker, and level adjusted by the front panel cue level control. The cue speaker
is muted by any input that is turned “on” and that was pre-selected during installation to activate the Mute 1 control bus.
The internal cue speaker may be disconnected and a remote speaker connected in its place. Consult the Output Board
Section for detailed information on wiring.
In addition, the cue signal maybe selected for monitoring by the headphone or monitor amplier select switches.
1.5.4 Output Routing
Each mixing channel can be routed to any combination of program (PGM), audition (AUD), and tel (TEL) mix buses.
The program and audition buses provide identical stereo performance allowing the audition output to be used as a back
up to the program bus, as a separate program bus, or to preview or record material. The TEL bus is a monaural.
1.5.5 Mix-Minus
Talk show hybrid telephone patches frequently require a return feed to the caller that does not contain his own voice (mix
minus). To accomplish this, the host should be routed to PGM and TEL and the caller to PGM only. The TEL bus should
then be fed back to the telephone hybrid and program audio used to feed the air chain. To prevent feedback in this ap-
plication, the studio monitor speakers should not be used.
A “fold back” feed can also be created by feeding all microphone inputs into the PGM bus, and feeding all other inputs
to both PGM and AUD mix buses. Switch the monitor speakers to AUD and feed the air chain with PGM. In this applica-
tion the mic inputs need not mute the monitor speakers, as no feedback will result.
1.5.6 Monitor Amplier Input Select
The monitor input select switches on the right hand side of the console allow monitoring of PGM, AUD, TEL, cue and
four external stereo inputs which are common to the monitor and headphone circuitry. All monitor outputs follow these
switches. Level adjustment for the control room monitor output is provided on the front panel. In addition, the control
room monitor output is dimmed to an level which has been preset by a trimmer on the Output Board by the Mute 1 con-
trol bus. A studio monitor output which is muted by the Mute 2 bus, and an unmuted monitor output is also provided. In
addition, a prefader, unmuted monitor output is available.
1.5.7 Headphone Amplier Input Select
The headphone input select switches on the right hand side of the console allow monitoring of program, audition, tel, cue
and four external stereo inputs which are common to the headphone and monitor circuitry. All headphone outputs follow
these switches. Level adjustment and connection for the operator’s headphones are provided on the front panel. In ad-
dition, a pre-fader headphone output is available for driving an external headphone amplier.

Radio Systems Millenium-A Console Page 9
1.5.8 VU Meter Selection (6 Channel Consoles Only)
The six channel console provides only three meters. One meter is dedicated to the TEL output, while the remaining two
are selected by a front panel switch to display either PGM or AUD outputs. The peak LEDs in the meters also follow the
VU meter select switch.
1.5.9 Remote Control
The Millenium Consoles provide extensive remote control using a 15-pin D connector located at each mixing channel.
Each channel has the capability to remote start almost any source. In addition, each channel provides inputs for remote
control of channel on/off and ready lamp illumination.
Sophisticated control interface is also accommodated with the use of the optional interface card (RS Part# 11022). See
Section 2.2.9 and Illustration E-1 for additional information.
1.5.10 Eight Position Switcher
Eight accessory switches are provided on the right-hand side of the console for user control of external equipment or the
optional Four Source Expander or Intercom Accessory boards. These switches and their associated LED indicators can
be wired directly to external equipment using two 15-pin D connectors mounted on the underside of the monitor control
board. Consult Illustration B-3 for more details.

Six Channel Control Board
2.1 Overview
One Six Channel Control Board is provided for every six input channels. This card sends DC control voltages to the Six
Channel Audio Board that:
Select A/B Inputs
Set output bus and cue routing
Set input level attenuation
Activate muting buses
Activate timer reset bus
This information is conveyed by a 16 conductor ribbon cables; one cable for every mixing channel.
Eighteen programming straps also reside on this board at each channel position and are used to set all unique channel
and input board functions.
The board also includes a 15-pin remote control connector for each channel providing user access to all remote and
channel functions.
Programming options available for each channel include:
Remote Control Options – by channel
Remote Control Options – by input
Muting Buses – by input
Timer Reset – by input
Cue Options- by channel
Cue Options – by input
Off (ready) lamp control operations – by input
2.2 Function Programming
2.2.1 Channel Power-Up Mode
It is sometimes desirable that certain channels ‘power up” in pre-set logic states. A common application for this feature is
that channel(s) associated with an automation system intended to run unattended, be set to power up with the channel
ON, and the correct input (e.g. A) and output bus (e.g. PGM) selected.
To set a channel to always power up in a specic pre-set mode - take the following steps:
1. Set the channel’s buttons in the desired INPUT, OUTPUT(S) and CUE modes
2. (For power up in the ON mode) - press and hold the ON switch for 5 seconds until the ON lamp blinks
3. (For power up in the OFF mode) - press and hold the OFF switch for 5 seconds until the OFF lamp blinks
4. Repeat this procedure on each channel where a special power-up mode is desired
5. Whenever the console power is re-cycled for any reason, these/this channel will power-up in its pre-set
mode
Notes:
ON or OFF lamps blink and then extinguish to indicate that the programming is stored
When programming the ON function, the OFF lamp may also blink depending on the remote control wiring/conguration
of the OFF lamp)
The default power-up mode is Input A / PGM / no CUE / Channel OFF
Fader position will not be memorized of changed, so faders must be left at standard operating level
It is still highly recommended that a good quality UPS of at least 1.5 KVA be installed prior to the console power supply
to provide temporary back-up power as well as power line ltering

Radio Systems Millenium-A Console Page 13
2.2.2 RemoteControlOptions–byChannel
Fader Start – The channel may be programmed to automatically turn on whenever the fader is brought out of the detent
(cue) position. All programmed channel on functions (e.g. remote starts or timer reset) will activate at this time.
Note that a special order fader with detent (RS Part # P&G) is required for this option.
Insert jumper A to activate.
Default is no jumper; no fader start
2.2.3 RemoteControlOptions–byInput
2.2.3.1 Pulse/HoldingRemoteControl
Insertion of these jumpers determine whether the remote control pins on the remote control connector pulse to ground
when the channel is turned on, or remain at ground potential for the duration of the channel ON state.
Pulse mode is generally used for cart machine and CD player control. Holding mode is generally selected for reel-to-
reel or turntable control.
Insert jumper H for input A – holding mode.
Default is no jumper; pulse mode.
Insert jumper C for input B – holding mode.
Default is no jumper; pulse mode.
2.2.3.2 SendThroughofRemoteOn/OffCommands
Installation of these optional jumpers will cause channel on/off commands which were initiated remotely (i.e. sent to the
channel via remote connector pins 1, 2, 5, or 12) to, in turn, create remote on/off output pulses (i.e. send remote control
commands to external equipment via remote connector pins 3, 4, 7, or 11). Normally, you would not want these remote
channel commands to be “sent through”, thereby creating a new command and potentially retriggering the remote device
via a false echo of the original command. This situation would apply when a remote device is wired to both control
and be controlled by an input channel; typically the case with a digital storage system that is wired to be both remotely
started by the channel and turn off the console channel at the end of the audio cut.
Insert jumper D to enable send through in input A.
Default is no jumper; no send through.
Insert jumper B to enable send through in input B.
Default is no jumper; no send through.
2.2.4 MutingBuses
Two muting buses, referred to as mute 1 and mute 2, perform the following functions:
Mute Bus 1 – mutes the cue speaker, dims monitor send #1, activates mute 1 send on Output Board connector J7.
Mute Bus 2 – mutes monitor send #2, activates mute 2 send on Output Board connector J7.
Insert jumper T for input A to mute bus 1.
Default is no jumper; no mute.
Insert jumper P for input A to mute bus 2.
Default is no jumper; no mute
Insert jumper V for input B to mute bus 1.
Default is no jumper; no mute
Insert jumper R for input B to mute bus 2.
Default is no jumper; no mute
SeeIllustrationB-1,Pg16

Radio Systems Millenium-A Console Page 14
2.2.5 TimerReset
The insertion of timer reset jumpers programs operation of the timer reset bus in conjunction with a selected input. The
bus will go low momentarily (100 ms) when the mixing channel is rst placed into the “On” mode. Depressing the “On”
button after the channel is already turned “On”, will result in another pulse of the bus.
Insert jumper S for input A to reset the timer.
Default is no jumper; no timer reset.
Insert jumper U for input B to reset the timer.
Default is no jumper; no timer reset.
2.2.6 CueOptionsbyChannel
2.2.6.1 CueonFaderDetent
Enable this function to allow the operator to put the channel in cue by dropping the fader into the detent (fully down)
position, Note that a special-order fader with detent (RS Part # P&G) is required for this option.
Insert jumper K to enable cue on detent
Default is no jumper; no cue on detent
2.2.6.2 AutoCue
Cue follows channel On/Off mode with this option enabled. The channel will automatically go into cue whenever the
channel is turned off. With this function enabled, cue still can be activated via the cue switch or fader detent.
Insert jumper J to enable auto cue
Default is no jumper insterted; no auto cue
2.2.6.3 CueDefeatonChannelON
Insert jumper F to cause the Cue Mode to be turned OFF whenever the channel is cycled from OFF to ON. Cue must
then be manually re-selected when the channel is turned OFF.
2.2.6.4 CueExclusive
Insert jumper N to cause any mix bus (which is selected) to automatically mute when cue function is engaged.
2.2.7 CueOptionsbyInput
Install these jumpers to disallow the channel from going into cue when a particular input is selected. This option is nor-
mally utilized for a control room mic input to avoid feedback from the cue speaker. When this option is enabled, the cue
button is automatically reprogrammed to act as a cough button (hold-to-mute) for that input.
Install jumper M for no cue on input A.
Default is no jumper; cue in input A.
Install jumper L for no cue on input B.
Default is no jumper; cue in input B.
SeeIllustrationB-1,Pg16

Radio Systems Millenium-A Console Page 15
2.2.8 Off(Ready)LampOptions
These jumpers allow for local (console) or remote (source) control of the channel off (ready) lamp via the remote control
connector.

2.2.9 RemoteControlConnector
A 15-pin D connector is provided on the Six Channel Control Board for each channel to access all remote functions.
All control (input) functions are activated via a momentary pull-to-ground, except the “cough” function, which must be
held to +15V. All control output functions are open lines which go low when the function is activated. Lamp drivers are
current-sinking inputs.
Two modes of remote control functionality are available via recently supplied PROMS. These modes are selected via the
installation of jumper E. In the default mode (E not installed,) remote control cue for IFB applications is provided. With
jumper E installed, “Classic” remote control functionality, identical to previous PROM versions is provided.
Refer to Illustration B-2 and B-3 for a pin-by-pin reference descriptions and wiring diagram.
2.2.10 OptionalRemoteBoard
Radio Systems’ optional Remote Board (RS Part # REMOTE) connects to the remote control connector and provides the
user with programmable relay interface for channel remote control outputs and opto-isolated input to channel on/off and
off lamp functions. Consult the interface option section for more details and pin-out and wiring diagrams.
2.2.11 MonitorControlBoard
One monitor card (RS Part #10887) is installed on the right-hand side of the console front panel. It provides all monitor
and clock switching and logic functions.
The monitor board also provides eight uncommitted, illuminated momentary switches for remote control of source
equipment. Access to these switch and LED connections is made with two 15-pin D connectors on the underside of the
board. Refer to Illustration B-3 for pin-out and wiring diagrams.
Radio Systems offers an optional logic card (RS Part # LOGIC) which adds push-on/push-off or interlocked switch func-
tions for these switches. This card also is used to interface the switches to the optional four source expander (RS Part
# ROUTER) or Intercom card (RS Part #INTERCOM). Consult the interface options section of this manual for more
information.

Six Channel Audio Board
3.1 Input Connectors
Illustration C-1 shows the location of all board input and patch point connectors as well as the pin-outs of the connectors
for 5-pin version consoles. Illustration C-2 shows the location of all board input and patch point connectors as well as
the pin-outs of the connectors for RJ-45 version consoles.
3.1.1 Input Wiring
Every input, from mic thru high level wires to the input connectors. One connector is provided for each channel “A” input
and another is provided for each “B” input. Each connector handles left and right balanced audio from the source equip-
ment.
5-pin consoles provide one ground terminal on each connector for the audio inputs. RJ-45 consoles provide a jumper
behind the input connector to select grounding options. Grounds should be connected at either the console or equip-
ment and not at both ends, to avoid ground loops. The console is usually used as the grounding reference point.
3.1.2 Unbalanced Audio
If an unbalanced audio source is to be connected to the console, single conductor shielded cable or two conductor
shielded cable with a foil shield around each conductor should be used. The audio should be connected to the + input,
while the shield should be connected to both the - input and ground. In this case, the shield is connected at both ends of
the cable.
3.1.3 Mono Inputs
For consoles produced after September, 2008: Inputs can be made mono by installing the mono/stereo select jumpers
as shown in Illustration C-1 (5-pin version console) or Illustration C-2 (RJ-45 version console).
For 5-pin version consoles produced prior to September, 2008: If one input (A or B), rather than an entire channel is to
be fed from a mono source, connect the Left+ input to the Right+ input and connect the Left- input to the Right- input. If
an entire channel is dedicated to mono sources (both A and B inputs) wire the input signal only to the Left Input and refer
to illustration C-1 for proper jumper placement on header J7.
3.2 Input Gain
3.2.1 Channel Sensitivity
The gain of an entire channel or the gain of an individual input can be changed to accommodate any mix of different
input source levels.
Overall channel gain is changed by installing jumpers into gain header J5 for the left channel and gain header J6 for the
right channel. The gain jumpers allow selection of four different overall gain range sensitivities; line (0 to +8 dBv), and
mic (-55 to -35 dBv), low (-20 to -10 dBv), and consumer (-10 to 0 dBv). Mic level sensitivity also requires the use of a
mic level attenuator dip carrier, as described in the next section on input sensitivity.
Changing gain headers effects the gain of the entire channel (both inputs). Refer to illustration C-3 for channel sensitiv-
ity strap programming.
3.2.2 Input Sensitivity
Individual input gains are changed by plugging any of 5 standard input attenuator DIP (IAD) carriers into the channel A or
B input attenuator DIP sockets. The IAD’s are used to reduce the sensitivity of an input after it has been increased via
the channel gain straps. This allows the use of sources of radically different output levels on the A and B inputs of the
same channel. An example where an IAD would be utilized, would be to allow a line level source to be connected to a
“B” input after the channel sensitivity had raised to consumer level to accommodate a CD player on an “A” input.
In other words, channel gain straps are set to increase channel sensitivity to accommodate the channel’s lowest level
source (such as a mic), and IAD’s are used to restore the original sensitivity, or any lower sensitivity for the other chan-
