Functional characteristics
1.8 microphone input, each microphone can adjust the volume independently, independent 48V fantasy power supply, composite cannon interface.
2.4 independent output, with one key mixing function. By default, you can choose 1, 5 to output in channel 1, 2, 6 to output in channel 2, or you can switch all inputs to output in channel 4.
3. Support U disk and Bluetooth audio playback (optional),
4. Stereo 3.5 headphone port line input, can input music, radio, etc., can be adjusted independently (without feedback function), will not produce hum caused by the power supply.
5. Professional recording output Lotus interface (without feedback), can be connected to recording equipment.
6. Stereo Lotus interface line output, independent volume control, can switch music with microphone mixing 1 output.
7. Adopt adaptive environmental whistling suppression algorithm, adopt high-speed floating point digital audio processor, can quickly and automatically eliminate whistling completely.
8. Using advanced subband noise reduction and elimination technology, built-in adaptive dynamic noise filter can filter out the background noise of the field environment but does not affect the voice signal transmission.
9. The system adopts intelligent bidirectional level control technology, which can obtain clear, continuous and uniform voice output, maintain the coherence of speech tone and clear speech, make the sense of listening more comfortable, and increase the gain up to 8-15dB. Microphone pickup distance is 0.5-1.2 meters
10. Built-in 24Bit A/D, D/A conversion; 32-bit DSP processor, 48KHz high-speed sampling.
11. One-key intelligent manual debugging, not affected by changes in the position, temperature, humidity, and decoration of the room environment, and no sound field debugging is required for system installation.
12. Keyboard lock function: After debugging the device, the administrator locks the panel keys to prevent non-administrators from performing operations.
13.2.0 Color display, display parameter status, menu can be switched between Chinese and English.
