RECEIVER FRONT PANEL
MODULATION - Indicates the modulation (audio level) of the incoming signal. The green LED
indicates an adequate modulation level. The red LED indicates maximum or "peak" modulation.
OUTPUT - VOLUME ATTENUATOR - An output attenuator is used to adjust the output level of the two
balanced outputs (XLR and 1/4") on the rear panel of the receiver. When the knob is in a fully clock­
wise position, the output at the jack will be 100mV when the signal is at full modulation. The attenuator
knob works like a regular volume control. As you turn the knob counter clockwise the audio output of
the receiver will be lowered.
NOTE: This control does not affect the MOD LEVEL display, the RF LED or the
POWER LED -- it also does not affect the output level of the "LINE OUT" RCA jack.
OFF - AUDIO MUTE - ON -- This slide switch turns the power off and on and provides a "mute"
function in the center position. This switch should be in the AUDIO MUTE position when the transmitter
MIC LEVEL or GAIN adjustment is being made. This muting function also prevents turn-on and turn-off
transients ("thumps" or "pops" in the sound system) that can occur when switching the receiver on and
off.
RF lamp -- Lights when the transmitter is turned on. If the carrier signal is too weak to produce a
quality signal, the lamp will go out.
POWER lamp -- Lights when the receiver is turned on.
