3. PROCESSOR/AMPLIFIER Selector Switch - selects either the inputs from the cinema
processor or power amplifiers for monitoring (see 5-8, pg. 8).
4. VU Bargraph - displays the level of the selected channels. The VU Bargraph may be
calibrated by the rear panel trim adjustment (see 12, pg. 8). The VU Bargraph operates
independently of the volume control (2).
5. TEST Jack - permits monitoring of the audio output of the CM-35/CM-35E. Inserting a
mono 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 8Ω impedance.
6. Internal Speaker
7. NORMAL/STANDBY Switch - when set to "Normal" routes the Exciter Supply module
(pg. 10) (13) DC output to the Exciter Supply output terminals (pg. 10) (12). In "Standby"
mode it routes 8 or 5 VAC Bypass power to the output terminals.
8. POWER Switch
9. AC EMERGENCY - DC NORMAL Indicator - this LED monitors the output of the exciter
supply. When the NORMAL/STANDBY switch is set to NORMAL, it monitors the output
of the Exciter Supply module; when in STANDBY mode, it monitors the AC Exciter
Supply output.
10. DC OUTPUT Indicator - this LED illuminates when the DC Exciter Supply module is
installed and working properly.
