Ambient Noise Compensator (ANC)
ANC (Ambient Noise Compensator) is a function that boosts or attenuates the level of the
program source according to the level that is being input via an ambient noise detection mic.
The ANC function provided by the DME7 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.
When placing this in the design sheet, select either Mono, Stereo or Multi as appropriate for
the program source. The illustrations used in the following explanation are for the case of
Stereo. Place the ambient noise detection mic in a location where it will not receive direct
sound from the speakers but will be close to the source of the ambient noise, such as on the
ceiling in the middle of the room above the crowd or audience, and at a distance from the
speakers.
Examples of use
Example 1: In a location where a speech is being given, automatically adjust the
output level of the program source up or down according to the level of
ambient noise (e.g., crowd noise).
Example 2: In a restaurant, adjust the background music (program source) according
to the noise of the surrounding conversation in order to maintain privacy.
Audio
Connect the signal from the ambient noise detection mic to the bottom input.
