Introduction Please read this entire manual before commencing your installation. The Ultra Stereo CM Series Projection Booth Monitor has been designed for high performance, ease of use, and years of trouble free service. Installation and setup of the monitors has been considerably simplified. No special tools are required. The built in VU meter and test jack give the technician immediate information about the status of the processor and all power amplifiers.
You will need to supply the following materials: • Shielded audio cable for connecting the CM Series to the cinema processor and power amplifier outputs. • Four 10-32 x 1/2" screws to mount the CM Series in the audio equipment rack.
-6- 1 3 4 5 6 7 8 9 1. Channel select buttons - pressing a Channel Select Button causes the corresponding LED to illuminate and the signal from that channel to be monitored. Any combination of ten channels can be selected. 2. Internal Digital or Analog Crossover Access Cover. 3. Crossover Bypass Switch - Switching this will cause the internal crossover to be bypassed or engaged and the condition will be indicated by its appropriate LED. 4.

Installation Mount the CM SERIES MONITOR 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.

Setting Monitor and Bargraph Levels: Set the processor main fader and amplifier levels so the house speakers are playing back at the normal listening level. Select some source material like pink noise. Set the “Processor/Amplifier” switch to “Processor”. With the monitor volume to “7”, adjust the “Processor” trimpot for a comfortable listening level. Set the bargraph trimpot for a reading in the middle range.
Crossover Bypass Setup This unit can be equipped with either the XTD-680D, a fully digital triamp crossover card, the XTA-680EA, an analog biamp crossover card or the XTB680B, a bypass card when no crossover functions are desired with the monitor. The XTD-680D and the XTA-680B are discussed in detail in their own instruction manuals. 1. Bypass Card XTB-680B: When using external crossovers, the CM Series must be equipped with a bypass card in the crossover slot.
