Setting Receiver Gain

The receiver gain control sets the audio signal level for the entire receiver and transmitter
system. Changes to the gain settings occur in realtime allowing for adjustments during
live performances. When adjusting the gain, monitor the audio meter levels to prevent
signal overloads.

Receiver Gain Controls

The gain can be adjusted by using the gain ▲▼ buttons or by entering the AUDIO menu
and using the control wheel.
Tip: To quickly adjust the gain, press and hold a gain button to enable accelerated
scrolling.

Reading the Audio Meter

The audio meter displays yellow, green, and red LEDs to indicate the audio signal level.
Audio peaks illuminate the LEDs for 2 seconds, while the RMS signal is displayed in
realtime.
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 ad-
ditional attenuation is needed, use the transmitter menu to set the INPUT PAD to -12dB.
Note: Illumination of the red OL (overload) LED indicates the internal limiter is engaged to
prevent digital clipping.
