Operation
Power
The AC line cord should be plugged into a three-wire, grounded outlet
providing 120V AC, 60 Hz. The power switch illuminates when unit is
switched ON.
MIC Control
Controls the amount of MIC signal heard at the output. Clockwise
increases the signal.
AUX Control
Controls the amount of AUX signal heard at the output. Clockwise
increases the signal.
Treble Control Switch
Provides a stepped increase or decrease in high frequency (above
1
0 kHz) heard at the output.The “Cut” position can help reduce high
frequency feedback. The “Flat” position provides no modification to
high frequency response. The “Boost” position provides more clairty
and intelligibility to speech.
Overload Protection
The amplifier output is protected against overload and shorted speaker
lines by a thermostat enclosed in the power transformer. If the breaker
opens, the amplifier will have no output. Set the Power switch to OFF
and wait a reasonable time for the breaker to reset. If the breaker trips
again, have the trouble investigated by a qualified technician.
