Features

Adopting 24BitA/D and D/A conversion; 24 bit DSP processor, 48KHz high-speed sampling;
Adaptive environment howling suppression algorithm is adopted, and high-speed floating point digital audio processing is adopted, which can quickly and automatically eliminate howling completely;
Adopting intelligent AGC bidirectional level control technology, ensuring clear, continuous, and no obvious fluctuations in speech output, and improving the gain by 6-15dB;
Supports one click elimination of whistling, without the need for deliberate sound field debugging;
Support signal generator, output pink noise with one button, and calibrate sound field;
Support level gain switch, which can adjust the level output value according to the actual situation;
Support digital pressure limiter: it can protect the horn from sudden high sound pressure damage;
Control type: manual operation, one click BYPASS, one click ACTIVE, achieving one click suppression effect, the operation is very simple;
Interface description: Front panel: Two input signal level display lights, two function selection keys, two sets of function indicator lights, power switch;
Rear panel: power interface (built-in fuse), 2-way XLR, 2-way TRS, 1-way RCA, 1-way input; One XLR, one TRS, and one RCA output line; Gain adjustment knob.
