DP-L2 CU
Ambient Noise Controller
DP-L2
The DP-L2 is a digital audio processor equipped with 2#83 Input, 2 #83Output, 1 ambient noise sensor microphone input and 1 #83monitor 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. It can be mounted in an EIA Standard equipment rack (1 unit size).
- Digital audio processor adjusts BGM / announcement sound volume to match changes of ambient noise
- Automatic and accurate input and output sound level adjustment
- Output excluded from ambient noise sensing

Fully digital ambient noise-controlled volume control to automatically adjust the volume of a signal to the ambient noise (ANC), with integrated automatic volume adjustment for constant volume of music transfers (ALC). The intelligent control prevents the influence of the volume by the wanted signal so that the placement of the microphone for the recording of the ambient noise is completely uncritical; There is no risk of a "built-up oscillation" of the signal, even if it is louder than the ambient noise.
Phantom power supply for sensor microphone can be activated.
Adjustment of the relationship between change of ambient noise and change the volume of the signal range of the volume and maximum volume. Evaluation of the ambient noise without weight or A weight with 3 adjustable frequency bands. Listening ability for the sensor input. Disable the controls to avoid accidental adjustment of parameters possible.
Two-channel version, which can be operated either in stereo or mixing. Bridging the inputs to the outputs during a power failure.
Display of input and output levels for each channel, as well as the volume adjustment of the ALC and the ambient noise-controlled volume control.
