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 additional 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.
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 by Rx MUTED message appearing
on the receiver display in place of the gain value.
Note: Receiver gain is disabled for muted channels to prevent unexpected changes in audio levels.
