OUR PART # DP-L2
The TOA DP-L2 Digital Ambient Noise Controller is a rack-mountable digital audio processor that automatically adjusts output volume in response to changing ambient noise levels. Typical applications include airports, shopping malls and restaurants.
Conventional ambient noise controllers simply add the output to the ambient noise, making manual compensation adjustments necessary. The DP-L2 features a superior automatic level control (ALC) algorithm that automatically adjusts the input signal to maintain a level suitable for the surrounding ambient noise level, ensuring an appropriate input signal level at all times.
The DP-L2 has two balanced Line Inputs and Outputs, one Ambient Noise Sensor Microphone Input and one Monitor Output . A range of microphones may be used for detecting ambient noise, including ceiling flush-mounted, dynamic and condenser types. Front panel LCD and controls allow easy adjustment of all functions with input, output, ALC and ANC level metering. A key-lock protect function prevents accidental changes in front-panel settings.
The DP-L2 is backed with TOA’s five year product warranty.
