Functional characteristics
1.4 way balanced microphone \ line input, 4 way balanced audio output, using phoenix interface;
2. Custom operating software, so that the configuration becomes more flexible, can control different specifications of DSP;
3. Built-in USB sound card, connected to the computer can achieve audio signal transmission, support recording and teleconference
4. Provide terminal user interface to realize centralized control of multiple devices, and third-party devices can be controlled through UDP, RS232, RS485 of the machine;
5. With AFC(feedback suppression) AEC echo cancellation, ANS(noise suppression), AGC(automatic benefit) benefit sharing threshold automatic mixing and other processing modules;
6. Each channel has independent adaptive feedback suppression, automatic discovery of feedback points, and automatic suppression;
7. Full function matrix mixing, input mixing level can be adjusted;
8.8 GPIOs can be configured independently for input and output, and can be used as independent ADCs when configured for input;
9. Support channel bay, LINK and packet functions;
10. Support R232&UDP central control, UDP port can be set freely, you can view the control software code;
11. The processor chip adopts ADI architecture, not less than 40bit DSP floating point arithmetic engine, and provides free configuration software architecture;
12. A variety of control methods can be managed through web pages, mobile phones, tablets, key panels, touch panels, etc.
