Installation/Wiring/Operation
1.1 Console Placement
Because neither ventilation nor 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 pan.
1.2 Opening the Console
A “T”-shaped lifter is provided to open the console. The external lifter discourages unauthorized access to console
electronics. Keep it in a secure place. Resist the urge to use the right-hand rotary knobs to raise the console lid as this
will quickly result in damage to these faders.
This lifter can be inserted in any fader slot, rotated 900 and used to raise the lid. Once the lid is opened, pull the two
hinges 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.
1.3 Power Supply
1.3.1 Installation
All console operating voltages are provided by the external power supply that connects to the console via a multi con-
ductor cable. A ten-foot length is provided as standard equipment. Longer lengths, up to 20 feet, are available from
the factory.
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
mounting screw on the front right hand side of the Output Board. Plug the 10 position connector into J3 and the 4
position connector into J4. Take extreme care to plug these connectors in with the correct orientation - locking tab to
locking tab (with cables exiting 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
supply. 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.
1.4 Wiring Access Layout
1.4.1 Audio Inputs
All audio inputs wire to connectors at the rear the Six Channel Mixer Board(s) on the base of the console. One Six
Channel Input Mother Board is utilized for every 6 audio channels and supports and houses any combination of up to
six plug-in Analog or digital Input Daughter Cards. Analog or digital inputs are wired via the same audio connectors.
Pin-out diagrams are provided in the Six Channel Mixer Board section.
1.4.2 Audio Outputs
All audio outputs wire to connectors at the rear of the Analog and Digital Output Boards on the right-hand pan of the
console. Note that these two circuit boards are stacked, with the digital board on top. The lower Analog board houses
all analog Program Outputs, External monitor inputs, Monitor sends and Talkback and muting audio and control. The
upper digital output board houses all digital program outputs, as well as analog and digital Mix Minus outputs.

Radio Systems Millenium-D Digital Console Page 6
1.4.3 Control
The front panel mounted Six Channel Control Board houses one 15 pin D connector to wire each channel’s remote
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.
Use the included 15-pin D connector ribbon extenders to plug in the mating D connectors external to the console, as
internal clearance for these connectors is not available inside the console.
1.4.4 Audio Connectors
Millenium Digital consoles may be ordered with 5-pin removable barrier strip connectors or with RJ-45 connectors for
all audio inputs and outputs. Consult the circuit board layout diagrams in the Six-Channel Mixer board and the Output
and Meter Board section of this manual for connector locations and wiring pin-outs.
1.4.5 Wiring Quick Connectors
The 5-pin barrier strip connectors are identical to those that are used in Millenium Analog consoles. When hand wir-
ing 5-pin removable barrier strip connectors, use 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. Insert the cable into the connector
and tighten the screw. If desired, first tin the cable to ensure a secure connection.
The RJ-45 connectors conform to the StudioHub+ standards for analog and digital CAT-5 based wiring. When using
the RJ-45 connectors, conform wiring to 568B CAT-5 standards and follow standard IT CAT-5 practices, or utilize pre-
made StudioHub+ wiring and accessories. See http://www.studiohub.com for more information.
StudioHub+ wiring harnesses that bring all input and output connections to convenient connection blocks outside the
console are available from Radio Systems. Consult the factory for literature.
1.4.6 Grounding and Shielding
The installer should elect whether cable shields will terminate (connect) on the equipment side or console side. The
general rule is that shields should not be terminated on both to avoid ground loops.
For shields that do terminate on the console side, on-board jumpers are provided for every input and output, analog
and digital on both the Six-Channel Mixer Board and the Output Boards to allow the programming of the following
ground options for each cable:
1- Unterminated; insert no jumper for the ground to float
2- Chassis Terminate; insert a jumper between the center and “CH” pins to connect the cable ground to the console
chassis ground. This option is recommended for digital (AES-EBU) inputs and most analog signal.
3- Circuit Board Terminate; insert a jumper between the center and “CB” pins to connect the cable ground to the con-
sole circuit board grounds. In the case of the Six-Channel Mixer Board this will connect the cable ground to separate
and isolated console ground buses for both the Analog and digital daughter plug-in cards. This option is recommend-
ed for some Analog signals (AES-EBU), inputs and most analog signals.
1.5 Operation
Millenium digital Consoles have been designed to offer the greatest combination of user flexibility and operating ease.
Foremost, the console should be installed and operated in accordance with station format, personnel habits and engi-
neering principles. However, the following sections suggest some operational possibilities that were considered in the
console design.
1.5.1 Input Assignment
Traditionally, commonly used inputs are assigned to input “A”. This gives the operator quick assurance of proper input
selection.

Radio Systems Millenium-D Digital Console Page 7
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, install the cue inhibit jumpers on the section of the Six Channel Control Board associ-
ated 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 amplifier select switches.
1.5.4 Output Routing
Each mixing channel can be routed to any combination of PROGRAM.1, PROGRAM.2, and PROGRAM.3 mix buses.
All buses provide identical stereo performance allowing them to be used as a back up to the airchain, as a separate
program bus, or to preview or record material. Note that PROGRAM.3 features an additional analog mixed mono out-
put.
1.5.5 Utility Buses
Millenium digital consoles feature 10 fully programmable utility buses. Via software programming every input may be
routed to any mix minus bus on a pre or post fader, or pre or post on-off switch basis.
Applications for the Utility buses include traditional “mix minus” uses, fold-back monitoring special monitor sends and
intercom functions.
Mix minus configurations can ONLY be changed via the Millenium PC software link. Consult the software section for
connection, programming and configuration options.
Note that UTILITY buses 1 & 6 are genrally utilized for PROGRAM.3
1.5.6 Mix-Minus via the PROGRAM.3 (formerly the “TEL” Bus)
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 may be routed to PROGRAM.1 and PROGRAM.3 and the caller to PRO-
GRAM.1 only. The PROGRAM.3 bus should then be fed back to the telephone hybrid and Program audio used to feed
the air chain. To prevent feedback in this application, the studio monitor speakers should not be used.
A “fold back” feed can also be created by feeding all microphone inputs into the PROGRAM.1 mix bus, and feeding
all other inputs to both PROGRAM.1 and PROGRAM.2 mix buses. Switch the monitor speakers to PROGRAM.2 and
feed the air chain with program signal. In this application, the mic inputs need not mute the monitor speakers, as no
feedback will result.
1.5.7 Monitor Amplifier Output Select
The monitor input select switches on the right-hand side of the console allow monitoring of the PROGRAM buses, 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 a level that has been preset by a trimmer on the Output Board by the Mute 1
control bus. A studio monitor output that is muted by the Mute 2 bus, and an unmuted monitor output are also provid-
ed. In addition, a prefader, unmuted monitor output is available.

Radio Systems Millenium-D Digital Console Page 8
1.5.8 Headphone Amplifier Output Select
The headphone input select switches on the right-hand side of the console allow monitoring of the PROGRAM buses,
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 addition, a pre-fader headphone output is available for driving an external headphone amplifier.
1.5.9 Remote Control
The Millenium Consoles provide extensive remote control interface ability via a 15 pin D connector located at each mix-
ing 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 via the use of the optional interface card (RS Part# REMOTE).
See Section 2.2.11 and Illustration E-1 for additional information.
Use the included 15-pin D connector ribbon extenders to plug in the mating D connectors external to the console, as
internal clearance for these connectors is not available inside the console.
1.5.10 Eight Position Switcher
Eight accessory switchers are provided on the right-hand side of the console control panel for optional user control of
external equipment, console accessory boards and mix-minus sends. The switches and their associated LED indica-
tors are wired directly to the digital output board and read by the digital processor. Connections for accessory boards
and special external switching are then made directly to connectors J39 and J43 on the digital out-put board. Consult
section 2.3 in the Six Channel Control Board section and diagrams D-3 and D-4 in the Output Board section for more
information.
Consult the “8 Position Switches” page in the “Software” section of this
manual for optional switch functionality assignment.
1.5.11 Console Clock Timer
All Millenium consoles include a Radio Systems CT-2002 clock/timer in the upper right section of the console over-
bridge. Front panel console controls are provided to locally set the time of day and control timer functions. An IR
Remote Control optionally available to set timer down times. Time of Day displays function as clocks or timers and may
also be used as slaved clock display synchronized from either RS Timecode, SMPTE Timecode, or a Top-of-Hour reset
pulse.
Consult illustrations A-1 and A-2 at the end of this section for clock wiring and operation.
