Limited Warranty; Exclusion of Certain Damages
Operation
Power:
The Power Switch applies power to the amplifier; it does
not control any associated equipment which may be connected to
the auxiliary power receptacle on the rear panel. The switch lamp
will illuminate when power has been applied to the unit.
Lo-Cut Filter Switch:
The LO-CUT filter switch, located on the
rear panel, provides 10 dB attenuation at 100 Hz.
Input Level Control:
The Input Level control (screwdriver-ad-
justable), located on the rear panel, is used to adjust the input sig-
nal applied to the amplifier. Turn the control clockwise to increase
the level.
Caution:
Many loudspeakers may be damaged if overdriven.
Therefore, always begin system setup with the Input Level
control fully counterclockwise and gradually increase the setting to
obtain the desired output level.
Thermal Cut-Out
The amplifier is protected by a thermal cut-out which should not
trip under normal conditions. If it trips, check for inadequate ven-
tilation of the unit or overloading. The cut-out will automatically
reset after cooling.
Circuit Breaker:
If the AC circuit breaker opens, the power switch
lamp will go out and the amplifier will have no output; however, there
will be power at the AUX POWER receptacle on the rear panel. Set
the POWER switch to OFF and momentarily depress the red but-
ton on the circuit breaker to reset it. Return the POWER switch to
ON. If the circuit breaker trips again, do not attempt to reset it; have
the trouble investigated by a qualified technician.
