Configuring a Mod Loss Backup Preset

The NV30LT-N contains an audio level detection circuit that can be used, when enabled, to allow 
switching to a secondary (backup) audio input source upon the loss of the primary source. Configure 
the desired transmitter preset to perform this function as follows (refer also to Section 2 of this manual 
for operating instructions of the front panel (UI) and remote (AUI) interfaces:

NOTE

: You must configure a minimum of two presets to allow this feature to operate. One preset will 

act as the primary , or normal operating preset. The second preset will act as the secondary, or backup 
audio preset. Configure the backup audio preset first.

Configuring the Backup Audio Preset
