2.4. 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.
Connect the signal from the ambient noise detection mic to the bottom input.
