MD8800 Smart Audio Matrix

Product Features:

1.450MHz high-speed DSP processor + 48KHz/24-bit sampling: Precise processing with no loss of detail;

2. Features 8 balanced inputs + 8 balanced outputs (Phoenix connector): stable transmission with enhanced anti-interference capability;

3. Utilizing a professional phoenix-head balanced connection method, each input and output channel features independent shielding design, effectively resisting external electromagnetic interference;

4. Equipped with a 2×2 sound card and USB-A interface: A one-stop solution for recording and remote conferencing needs;

5. Added a music playlist feature for the PC version, allowing music paths from the PC to be added to the software control for seamless music switching without frequent toggling to the PC playback interface;

6. Added a new recording function, which allows capturing sound from physical input channels via routing and storing it on the PC;

7. Added 8 new group control functions, allowing input and output channels to be grouped for control, enabling synchronized level and mute operations for channels within the same group;  

8. Multi-level sensitivity adjustment (0dB/-10dB/-20dB/-30dB/-40dB): Adapts to different signal sources with enhanced compatibility, allowing flexible adjustment based on input device signal strength (e.g., weak signals from microphones or strong signals from players). This prevents distortion caused by excessive signal strength or noise resulting from weak signals;  

9. Equipped with input AEC automatic echo cancellation and noise suppression functions, it allows flexible configuration of remote and local settings in video conferencing scenarios, effectively eliminating echo and noise interference;  

10 features sine wave, pink, and white noise testing functions;  

11. Features input feedback suppression notch + frequency shift function, with 8 input channels that can be freely configured. Two channels support feedback suppression with 32 dynamic notch points, and all 8 input channels offer 4 selectable frequency shift levels;

12. Input channel phantom power, gain, mute, polarity, delay, 9-band PEQ, high-pass and low-pass (Linkwitz: 12dB, 24dB, 36dB, 48dB; Bessel: 12dB, 18dB, 24dB, 36dB, 48dB; Butterworth: 6dB, 12dB, 18dB, 24dB, 36dB, 48dB), expander, compressor, automatic gain, white noise, pink noise, sine wave generator, channel control group settings, channel cloning, channel alignment settings, auto-mixing, 10-level priority;  

13. The output channel functions include: gain, mute, polarity, delay, 9-segment PEQ, high-low pass (Ningke: 12dB, 24dB, 36dB, 48dB, Beisel: 12dB, 18dB, 24dB, 36dB, 48dB, Butterworth: 6dB, 12dB, 18dB, 24dB, 36dB, 48dB), limiter;  

14. Wall panel control interface (Phoenix head wiring): Localized control is more flexible, and simple control panels can be installed on the walls of conference rooms, classrooms, and other scenes to achieve localized operations such as "volume adjustment, channel switching, and mute control";  

15. Bidirectional GPIO port: custom intelligent linkage;  

16.12 sets of user data memory: One click scene switching, doubling efficiency;  

17. Multi protocol control, adapted to different control scenarios;

18. Channel English naming (within 7 bytes): clearer device management;  

19. Equipped with LAN control interface, directly connected/LAN for PC control;  

20. Web side control: Mobile/tablet can be adjusted at any time without installing software. Mobile, tablet or computer can access it by entering the device IP through the browser without installing a dedicated APP;
