TOA Electronics Digital Ambient Noise Controller, 20Hz-20kHz Frequency Response

While the TOA Electronics Digital Ambient Noise Controller may appear to be a standard digital audio processor, it stands out with its advanced automatic volume adjustment capabilities that respond to fluctuating ambient noise levels. This professional-grade device is perfect for high-demand environments such as airports and shopping malls, where it expertly manages voice announcement systems.Its innovative automatic level control (ALC) algorithm is a standout feature, adjusting the input signal in real-time to match the surrounding ambient noise level. This ensures a consistently appropriate input signal level, regardless of the ambient noise. The DP-L2 model is sophisticated enough to differentiate between its own output and the surrounding noise, providing more accurate level balancing.The high-quality device is equipped with balanced line inputs and outputs, an ambient noise sensor microphone input, and a monitor output. It supports a range of microphones for detecting ambient noise, including ceiling-mounted, dynamic, and condenser types. The device's ambient noise control (ANC) function, complete with a 4-LED metering system, automatically adjusts the output gain to match changes in ambient noise levels. This ensures that the unit's output sound level is always distinct from the ambient noise levels, providing more precise automatic noise control.The maximum output function serves as a limiter, while the microphone input reference level adjustment function comes with a phantom power switch. The front panel features an eight-LED input and output level metering system for easy monitoring. To prevent accidental changes, a built-in key lock function is included, ensuring your settings remain secure and consistent. In summary, the TOA Electronics Digital Ambient Noise Controller is a versatile, high-performance tool for managing and controlling ambient noise within a 20Hz-20kHz frequency range, making it an essential device for any professional audio setup.
