CONTROLLER
BOESCRIPTION
The DP-L2 is a digital audio processor equipped with 2 X Input, 2 X Output, 1 X ambient noise
sensor microphone input and 1 X monitor output and features easy setting of each function by the
front panel operation. It is equipped with an ambient noise control function (The ANC function
distinguishes between the unit's output sound and the ambient noise. The unit's output sound is not
detected as noise.) and an automatic level control function that keeps the input signal level constant.
[t can be mounted in an EIA Standard equipment rack (1 unit size).
