Manufacturer Information On The Unit:

The TOA DP-L2 CU Digital Ambient Noise Controller is the easy, automatic solution to the problem of keeping BGM and announcements audible and understandable when the ambient noise levels at an airport check-in counter or boarding gate, or a shopping mall, restaurant or pub, are higher because a large number of people are present. Furthermore, the DP-L2 CU also works to keep music and information audio from reaching levels that are irritating to customers and staff when the surrounding ambient noise levels are not so high.

Automatic and Accurate Input and Output Sound Level Adjustment: The DP-L2 CU is a digital audio processor with an ambient noise control (ANC) function that makes automatic changes in its output sound levels depending on the amount of surrounding noise, and an automatic level control (ALC) function that automatically adjusts the input signal level so it is appropriate at all times. BGM and announcements remain audible and understandable at all times, with no annoying loudness for customers and employees.

Output Excluded from Ambient Noise Sensing: The ambient noise sensor microphone enables accurate measurement of BGM/announcement listening-area noise levels. In addition, for complete accuracy, a DP-L2 CU feature exclusive to TOA automatically separates the unit’s own output from the calculation of the ambient sound level, instead of just mixing all sound sources together, meaning that the output is not detected as noise. Additionally, a monitoring feature makes it possible to check the sound collected by the ambient noise sensor microphone.
