While processing microphone signal, the device constantly analyzes frequencies and phase positions of the input and output signals and processes the signal smartly when the frequencies and phase positions are super-positioned to destruct conditions for positive feedback and inhibit whistling. The product is capable of detecting whistling points in field automatically, filtering sound through the DSP system, fully digitalizing smart high-speed feedback for bass compensation and automatic sound mixing, minimizing signal returns, automatically adapting to acoustic environment without commissioning and swift calibration, ensuring sound quality and reducing delay. The high, medium and low input level selection prevents loss of peak inputs, effectively increases pickup distance of 30-100cm and increases gains of the other microphone with strong signal input.

Technical characteristics
1. Ultra-wide frequency response circuit technology, without inflexion and metallic final sound and powerfully inhibiting echo.
2. Digital frequency shifting technology powerfully prevents whistling and produces mellow and full, and stable sound, without unstable and dry sound.
3. Super-stable: built-in crystal oscillation, software algorithm and excellent stability, slightly affected by temperature and external environment.
4. Appropriate audio spectrum is tailored based on applications to enhance system gain significantly.
5. 4-line 48V phantom power supply or Cannon input port.
