Each Ambient Sensing Leveler device 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 device then applies gain to the input signal based on the detected ambient level.
The different variants of the device provide the following features:
Continuous sensing |
The ambient sound level is measured continuously. |
Gap sensing |
The ambient sound level is measured during gaps in the program material. The Gap version of the Ambient Sensing Leveler is easier to set up and consumes fewer DSP resources than the regular version. Also, the device accurately calculates the necessary gain even when there are long gaps in the program material. |
Router |
The device switches inputs based on the ambient noise level. |
