Installation

Mount the CM Series

The ideal place for the CM Series Monitor is in the sound rack or

projector console between the stereo processor and power

amplifiers. DB25 and HD15 connectors are available on the back plane

to make installation quick and easy. Alternatively, terminal blocks allow

the use of stripped and tinned wire. They are pluggable for easy service

and trouble shooting.

Monitor Hookup

1. Power: Connect the unit to the AC power outlet using the standard

IEC cable provided. Any power source from 100-250VAC, 50-60 Hz

will be sufficient.

2. Monitor Inputs From Processor Outputs: Use the male-female

25 pin D cable to connect the output of the cinema processor to the

main input of the CM Series. If “EX” channels are to be used, then plug

an additional male-female 25 pin D cable from the “Optional Outputs”

at the processor to the “Optional Inputs” of the CM Series.

3. Crossover Outputs to Power Amplifier Inputs: The CM Series

utilizes HD15 connectors that mate with several popular amplifiers.

Plug one end of the “VGA” HD15 cable into the chassis connector on

the rear of the CM Series. Plug the other end of the cable into the

appropriate amplifier. The VGA cable not only sends the CM Series

crossover signal to the amplifiers, but also sends a power amp output

signal back to the CM Series monitor. This vastly simplifies rack wiring.

USL, Inc. stocks 2’, 4’ and 6’ long VGA cables.

Terminal blocks are also provided on the back of the CM Series chassis

to allow wiring to traditional amplifiers without the HD15 interface. All

crossover outputs are balanced. Please use two conductor shielded

cable to minimize ground loops and hum. Connect each of the crossover

channel outputs to the appropriate amplifier inputs.

4. Monitor Inputs From Power Amplifier Outputs: When VGA cables

are NOT being used, the amplifier outputs must be connected to

terminal blocks 2 & 3. Unshielded wire can be used to connect the

output of the amplifiers to the appropriate monitor speaker.

Inputs on the rear panel of the CM Series: All of these inputs are

unbalanced except for the subwoofer.

NOTE: you must select “EX” or

NORMAL (non “EX”) channel routing

using the DIP switches on the rear

panel of the CM Series.
