Lectrosonics R172 - Manual (Page 3)

RECEIVER FRONT PANEL
Front panel controls on the R172 are identical for each channel and operate independently from each other.
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 LEVEL -- An output attenuator is used to reduce the audio output level of the receiver. Reduces the audio
output levels of the XLR jacks in the rear by rotating the knob counter-clockwise.
NOTE: This control does not affect the MODULATION display, the RF LED or the POWER LED -­
it also does not affect the output level of the "LINE LEVEL" RCA jack.
RF LED -- Light when the transmitters are turned on. If the carrier signal is too weak to produce a quality signal,
the lamp will go out. Each channel has it's own independent RF LED.
POWER LED -- Lights when the receiver is turned on.
OFF ON SWITCH - This switch activates the receiver when set to the "ON" position.
