When setting up the receiver, adjust the gain so that the average signal LED levels are solid green and occasionally yellow,
with only the highest peaks causing the red LED to illuminate.
Tip: If a vocalist is overloading a bodypack transmitter, try lowing the receiver gain. If additional attenuation is needed, use the transmitter menu to set the IN
PUT PAD to -12dB.
Note: Illumination of the red OL (overload) LED indicates the internal limiter is engaged to prevent digital clipping.
Muting a Receiver Channel Audio Output
The audio output of each receiver channel can be independently muted to prevent audio from passing. Mute status is indicated

To correct, select INPUT PAD from the main menu and attenuate the input signal by 12 dB. If the warning persists, reduce the

Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption key which is shared with a the transmitter during an IR
sync. Transmitters and receivers that share an encryption key form a protected audio path, preventing unauthorized access
from other receivers.
