Model Number: FB8000A
1. Functional features:
Using adaptive ambient acoustic noise suppression algorithm, high-speed floating-point digital audio processor and advanced sub-band noise reduction and cancellation technology, it can quickly and automatically completely eliminate acoustic noise and background noise.
Built-in 24Bit A/D, D/A conversion; 32-bit high-speed DSP processor.
The working mode of fully automatic operation, without manual debugging, no matter the change of location, temperature, humidity and decoration in the room environment, the system installation does not need to be debugged by the sound field, and it is accurate and reliable and simple to use.
The built-in adaptive dynamic noise filter can filter out the background noise of the on-site environment without affecting the voice signal transmission. Intelligent dynamic gain matching technology improves the distance of voice pickup and obtains clear, continuous and stable voice signals
Intelligent dynamic environmental noise reduction technology can filter out the background noise of the on-site environment without affecting the high-quality transmission of voice signals. Improve signal-to-noise ratio and improve sound quality.
The 8-way microphone input volume potentiometer is independently adjustable, and the +48V phantom power supply is independently controlled.
Built-in professional audio isolator to effectively isolate the noise caused by potential difference and high-frequency interference with various digital equipment such as computers.
2.0-inch TFT color screen, display function status and signal status
The line music signal has the function of adjusting the high and low tones, and has the function of Bluetooth and U disk playback.
