“ANC” screen
In this screen you can make settings for the “Ambient Noise Compensator” (subsequently
called “ANC”).
ANC is a function that boosts or attenuates the output signal from the MTX according to
the level that is being input via an ambient noise detection mic. The ANC function
provided by the MTX is a gap-type ANC that detects silent intervals such as between
songs, detects the noise level during those intervals, and varies the level accordingly.
