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 90
0
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.
