Installation

Mount the CM-60

The ideal place for the CM-60 Monitor is in the sound rack or

projector console between the stereo processor and power

amplifiers. The terminal blocks on the rear of the CM-60 are

designed to facilitate the application of stripped and tinned wire

leads and are pluggable for easy service and trouble shooting.

Monitor Hookup

1. Power: Use 18AWG wire provided to connect the wall

transformer to the CM-60.

2. Processor Outputs: Use shielded wire to connect the line-

level outputs from the cinema processor to the CM-60. There is

one terminal for the "hot" signal from each channel, and one

common "E" (ground) terminal. The CM-60 also has a DB-25

computer style connector that matches the Ultra

processor, as well as many other processors. When the DB-25

connector is used, the processor output connections on the

terminal block should be left unconnected.

3. Amplifier Outputs: Use any suitable wire to connect the

power amplifier's speaker outputs to the "Amplifier Outputs"

terminals on the CM-60. The CM-60 has three inputs for each of

the three front channels for use with bi-amplified or tri-amplified

systems. For systems that are not bi or tri-amplified, use only the

low frequency inputs (Ll, Cl, Rl). For bi-amplified systems use

only the low frequency (Ll, Cl, Rl) and high frequency (Lh, Ch,

Rh) inputs. Unused inputs can be left unconnected. The sur-

round and subwoofer inputs are balanced and may be used with

bridged or other non-grounded amp systems. The amplifiers may

also be connected to the CM-60 using a 50-conductor ribbon

cable and interface boards at each amplifier. Contact the factory

for more information on this convenient system.
