Advanced Transmitter Features
RF MUTE
Use this to turn on a transmitter without interfering with the RF spectrum.
Press and hold exit during power-on until RF MUTED is displayed. To un-mute, restart the transmitter.
MIC.OFFSET
MIC.OFFSET compensates for signal level differences between transmitters that share the same receiver channel.
Set the offset gain on a low signal level transmitter to match a louder transmitter: UTILITY > MIC.OFFSET
Note: For normal gain adjustments, use the receiver gain buttons.
Transmitter Audio Mute Mode
Mute Mode reconfigures the transmitter power switch to act a mute switch for the audio. Using the switch, the audio can be
easily turned on or muted by presenters, sports referees, or anyone who periodically needs to speak. When the audio is muted,
the transmitter RF signal remains on and ready at all times.
Note: Mute Mode can be selected as an IR PRESET option.
To set a transmitter to Mute Mode:
From the transmitter menu: UTILITY > MUTE MODE
Use the arrows to select ON or OFF.
Press enter to save.
Tip: The transmitter LED turns red when audio is muted and turns green when audio is enabled. The display of the transmitter
will show AUDIO MUTED and the receiver display will show Tx Muted.
Note: Mute Mode must be set to OFF in order to use the power switch to turn off the transmitter.
