Ambient Sensing Leveler (continuous sensing)

Purpose

The Ambient Sensing Leveler provides an automatic volume control when the ambient noise levels in a venue start to affect the perceptibility of paging announcements and background music.

The device measures the following:

• The incoming program material level.
• The ambient level from the incoming zone (using a microphone connected to the sense input).
• The output level of the Ambient Sensing Leveler device.

The ambient sound level is measured continuously. The device then applies gain to the input signal based on the detected ambient level. This allows different equalization settings to be selected as the ambient noise level rises in the room.
