The RoomSense mic cannot be turned off but it can be controlled via MIX SECTION:
1. AMBIENT – RoomSense uses the onboard mics and passes that signal via the headphone output. Control for RoomSense level can be found in the MIX section.
To avoid feedback, the RoomSense output is only passed to the headphone output and not the XLR output.

2. AMBIENT/AUTO – In addition to the ability to output RoomSense sounds via the headphone mix, the onboard RoomSense mics will also listen to musical information from the surrounding environment (a single instrument or even your whole band will work!) to determine the KEY/SCALE for harmony/hardtune.

3. VOICE – The RoomSense mics are used as the primary vocal input. This action is only available via headphones.
