A: Features
⊙ 8-way microphone input, independent volume adjustment for each microphone, independent 48V power supply. 4 independent outputs. Line input lotus interface, independent volume control (into the feedback function). Music input Lotus interface, independent volume control (without entering the feedback function).
⊙, Line output lotus interface, independent volume control. Can switch mixed 1 output
⊙, Bluetooth or U disk audio connection input, 3.5 port computer signal input will not produce humming sound caused by power supply.
⊙, Professional recording output Lotus interface (without feedback).
⊙Adopt adaptive environmental whistle suppression algorithm, high-speed floating-point digital audio processor and advanced sub-band noise reduction and elimination technology, which can quickly and automatically eliminate whistling and background noise..
⊙ Built-in adaptive dynamic noise filter, which can filter out the background noise of the scene environment without affecting the voice signal transmission. The intelligent two-way level control technology of the system can obtain clear, continuous and uniform voice output, maintain the coherence of the speech tone and the clear voice, and the hearing is comfortable, and the gain can be increased by 8-15dB. The pickup distance of the microphone is 0.5 -1.2 meters
⊙.Built-in 24Bit A/D, D/A conversion; 24-bit DSP processor, 96KHz high-speed sampling. Using high-speed floating-point operations
⊙One-key intelligent manual debugging, no matter the location, temperature, humidity and decoration of the room environment change, the system installation does not require sound field debugging.
⊙Keyboard lock function: After the administrator has debugged the device, the panel keys are locked to prevent non-administrators from operating. The menu can be switched between Chinese and English
⊙ 2.0 color display to show the parameter status
B: Applicable places: conference rooms, stadiums, multi-purpose halls, multimedia classrooms, etc.
