If there is an unusually large difference between the processor
and amplifier levels it may be necessary to go back and adjust
the Processor Level trimpot to match levels. Next, set the
Bargraph Level trimpot on the rear of the unit so the front panel
bargraph meter reads approximately 0VU.
With the bargraph meter set to read 0VU at normal auditorium
listening levels, the projectionist can tell at a glance if a film is
playing at the correct level.
Exciter Supply Setup
The Exciter Lamp Supply is built on the JBX printed circuit
board, which plugs into the back of the CM80E. This electronic
switching supply is adjustable from 3.7 to 8.5 VDC with a
maximum current output of 7 amps.
Use a minimum of 16ga. cable no more than 15 feet in length
(14ga. cable for up to 30 feet) to connect the Exciter Lamp to
the Exciter Lamp Supply Output terminals. Make sure the
negative (–) contact of the exciter lamp does not contact the
projector frame or any other possible common ground.
Set the AC Standby voltage by
loosening the jumper link and moving
to either the 8V or 5V position.
If the negative Exciter Lamp Supply terminal of
the CM-80E is connected to a chassis or
common ground, or is connected to the
projector chassis, then excessive hum or noise
may result.
Connect the Exciter
Lamp only to the
'–' output terminal on
the Exciter Lamp Supply
terminal block.
Some versions
have a single fuse
and line switch.
