The TOA DP-L2 Digital Ambient Noise Controller is a professional, rack-mountable audio processor designed to automatically adjust system volume in real time based on changing ambient noise levels. Ideal for dynamic public environments, the DP-L2 ensures announcements and background music remain clear and intelligible without constant manual adjustments.
This makes it an excellent solution for airports, shopping centers, restaurants, transit hubs, and other commercial facilities with fluctuating noise conditions.
Intelligent Automatic Level Control
Unlike conventional ambient noise systems that simply increase output volume, the DP-L2 uses TOA’s advanced Automatic Level Control (ALC) algorithm to intelligently adjust the input signal level. This approach delivers smoother, more consistent audio performance while preventing excessive volume changes and listener fatigue.
The result is balanced, natural-sounding audio that adapts seamlessly to real-world environments.
Flexible Inputs, Outputs & Monitoring
The DP-L2 features two balanced line inputs and outputs, along with a dedicated ambient noise sensor microphone input and a monitor output for system verification. It supports a wide range of microphone types, including ceiling flush-mount, dynamic, and condenser microphones, allowing flexible system design.
A front-panel LCD with clear metering for input, output, ALC, and ANC levels simplifies setup and monitoring, while a key-lock function protects settings from accidental changes.
