Features
- Adaptive environmental whistle suppression algorithm with high-speed floating point digital audio processor and advanced sub-band noise cancellation technology, which can quickly and automatically completely eliminate whistle and background noise.
- Built-in adaptive dynamic noise filter, which can filter out the background noise of the live environment but does not affect the voice signal transmission.
- Intelligent AGC bi-directional level control technology for clear, consistent and evenly sized speech output, maintaining coherent and clear speech tones, boosting gain by up to 6-8dB and microphone pick-up distance of 0.5-1.2m.
- Built-in 24Bit A/D, D/A conversion; 24-bit DSP floating point processor, 96KHz high speed sampling.
- One key intelligent manual-free debugging, regardless of changes in location, temperature, humidity and decoration in the room environment, the system is installed without the need for sound field debugging.
- Keyboard lock function: when the administrator has finished debugging the equipment, then the panel keys are locked to prevent non-administrators from operating.
- Menu can be switched between English and Chinese.
- 2" colour display shows the status of the given parameters.
