 DP-L2
Digital Ambient Noise Controller
NEW!
 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.
FEATURES
- Digital ambient noise control (ANC) function with 4-LED
metering automatically adjusts output gain to
match changes in ambient noise levels.
- Exclusive TOA algorithm distinguishes unit output sound level
from ambient noise levels, for more accurate control.
- Monitor output for sound picked up by the ambient noise
sensor microphone.
- Automatic level control feature with 4-LED metering
maintains input signal at a constant level by adjusting input
signals to appropriate levels when the sound level is too low.
- Sound volume is controlled without losing nuances of
speech or compromising background music sound quality.
This prevents unnatural sound effects that often results
when using conventional Automatic Gain Control (AGC) or compressor.
- Maximum Output function acts as a limiter.
- Sensor input reference level fine adjustment function.
- Sensor input phantom power.
- 8-LED input and output level metering.
- Auto input sensitivity setting and sensor input reference
level measurement function.
- Front panel LCD screen, keys and knobs ensuring easy access to all
settings.
- Built-in key lock function prevents unauthorized adjustment.
- Standard 1U-size (44.5mm/19-inch) with rack-mount hardware included.
- Five year warranty
