5.4.1 Main AC Power Switch
This is an environmentally sealed single-throw double pole switch that connects and
disconnects both the primary and neutral AC input lines to turn the unit on and off.
5.4.2 Electronics Panel Indicator LEDS
Power
:
LED illuminates in green when main power switch is on and AC is present.
Clipping
:
LED illuminates in yellow when input signal is too high. Excessive input signal level
will cause distortion on the output and may damage the amplifier if applied continuously.
When using the microphone, this means that the operator is shouting too loudly into the
microphone and should adjust their voice level or the position of the microphone with respect
to their mouth. When using an external audio device such as a CD player, this means that the
output volume on the CD player is set too high and should be turned down until the Clipping
LE
D no longer illuminates. The Clipping LED will not illuminate when using the LRAD’s
Control
Unit unless there is a malfunction in the Control Unit
or the LRAD’s preamp.
