XTM-300 Series Front Panel
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 eight 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. Volume Control - controls the volume of the internal speaker. The volume control has no effect on
the VU Bargraph display.
5. Processor/Amplifier Selector Switch - selects either the inputs from the cinema processor or power
amplifiers for monitoring.
6. VU Bargraph - displays the level of the selected channels. The VU Bargraph may be calibrated by
the rear panel trim adjustment. The VU Bargraph operates independently of the volume control (4).
7. Test Jack - permits monitoring of the audio output of the CM- 680. Inserting a mono or stereo 1/4”
phone plug here disables the internal speaker and routes the audio output to the Test Jack. Do
not connect any device here with less than 8 Ohms impedance.
