OPERATION
POWER
The front-panel rocker switch applies power to the mixer. An
integral pilot lamp illuminates when power has been applied.
LEVEL CONTROL
Set gain and filter controls on modules so equipped to mid­
rotation. Set the mixer (CHANNEL 1 through 6) level controls to
their full counterclockwise position. Control the level of each input
on the desired bus (A or B) with clockwise rotation of the ap­
propriate control. The overall output level is adjusted with the
appropriate MASTER control. The T.F.D level meter will il­
luminate red to indicate possible signal clipping conditions.
TONE CONTROL
When the Tone Control switches in the module cage are in the
OUT position, the front panel tone controls are disabled and the
tone response will be flat. To enable the front panel tone controls
for either bus, set the appropriate A or B control switch to the IN
position. Bass and treble tone controls provide ± lOdB cut/boost
at lOOHz and lOkHz, respectively.
VARIABLE MUTE
Operation of the variable-mute feature (0 to 60dB range)
requires a customer-supplied contact closure across the MUTE
terminals. This contact closure will mute the program input (PGM)
and any module set to priority level 1 or 2.
MAINTENANCE
Caution
There are no user-servieahle parts within the unit. Refer all
servicing to qualified sen’ice personnel
AC CIRCUIT BREAKER
If the AC circuit breaker trips, the power switch pilot lamp will
go out and there will be no output. Set the AC power switch to
OFF and depre.ss the red button on the circuit breaker to reset it.
Return the AC power switch to ON. Tf the breaker trips again, have
the trouble Investigated by a qualified technician.
THERMAL BREAKER
The thermal breaker will open when the temperature at the
output transistor heat sink reaches 105°C (221°F) on all models. If
the breaker opens, there will be no output but the power switch
pilot lamp will remain illuminated. Wait approximately two min­
utes for the breaker to reset. If the breaker resets and then opens
again, investigate the cause of the temperature overload. This may
be due to improper connections at the output terminals or excessive
environmental heat with inadequate ventilation.
