Receiver Gain Adjustment

The gain control sets the overall signal level for the system. The default gain level is 12 dB and
the available gain range is -18 to 42 dB, in 1 dB increments.
Set the gain to a level where the audio LED appears green or yellow, with only the highest audio
peaks causing the LED to occasionally turn red and engage the limiter. Reduce the gain if there is
audible distortion of the audio.
From the receiver home screen, use the arrow buttons to increase or decrease the gain:
• A single button press adjusts the gain in 1 dB increments
• Press and hold the button for larger adjustments
Test the transmitter at performance levels when adjusting the gain. Monitor the audio meter and
the audio LED to prevent overloads.

Control Lock Options for the Receiver and

Network Scan

The Network Scan feature automates frequency assignment by using a single receiver to scan
and deploy frequencies to all networked receiver within the same frequency band.
Network Scanning and Frequency Deployment
1. Connect receivers to an active Ethernet network. All receivers must be on the same subnet.
2. Prior to performing a network scan, turn on all receivers and al-
low 60 seconds for all receivers to join the network.
3. Choose a group or custom group for deployment on the receiv-
er that will be used to initiate the network scan.
4. To start a network scan, press the menu button and navi-
gate to the network scan menu. Press enter.
5. When the scan is complete, the displays of receivers waiting for frequencies will flash.
6. Press enter to deploy the frequencies or press menu to cancel the deployment.
7. The front panel LEDs on each receiver will blink when a de-
ployed frequency has been assigned.
Note: Full frequency deployment may not occur if the number of receivers in the network exceeds
the number of available frequencies in the selected group. Try another group or rescan after turn-
ing off unused receivers.
