FS-100 4-input 1-output Fully Automatic Digital Feedback Suppressor

Description

1. 1.8-channel balanced microphone/line input with 48V phantom power soft switch
2. Input gain step size is 6dB, with no less than 9 levels; applicable to MIC and LINE levels
3. 8-channel balanced line output
4. The audio processor can be connected to the network. Mobile phones, tablets, and computers can control the audio processor via wired or wireless network
5. Control microphone volume, microphone on/off, mute, adjust volume size in real time according to the speaker’s different conditions without going to the cabinet, ensuring the continuity of the meeting.
6. Adjust microphone and music equalization, compression, feedback, and view the status of each channel at any time.
7. The audio processor has two input and two output sound cards, supporting music playback, recording, and soft video conferences (such as: ZOOM, Tencent Meeting, DingTalk Meeting, etc.).
8. The computer is connected to the processor via USB cable, allowing music playback without connecting other cables.
9. The processor is connected to the computer via USB cable, enabling audio recording of the meeting, and can select a single channel, several channels, or all audio.
10. Built-in programmable central control function, supporting 1-channel 232, 1-channel 485 and UDP interfaces, and can be externally connected with 8-channel 232 expanders.
11. Can control the power supply, signal switching, environmental control, audio and other aspects of the system as a whole, achieving the one-click activation of the required functions of the system.
12. Supports user Android and Apple customized operation interface, and can manage up to 30 devices on the same interface;
13. Automatic gain control AGC ensures the stability of the audio system’s output volume, unaffected by the speaker’s distance from the microphone varying far and near affecting the volume in the audience area.
14. Supports gain sharing automatic mixing (AMC)
15. 4 GPIO can be independently configured for input and output, and can be used as an independent ADC when configuring input
16. 8-section British parametric equalization, providing 5 filter options: Parametric, Lowshelf, Highshelf, Lowpass, Highpass;
17. Two adaptive echo cancellation (AEC) and noise suppression (ANS)
18. Each channel should have no less than 8 points of adaptive feedback suppression (AFC);
Output channels should have:
20. No less than 8 sections of PEQ, filter, delay, limiter.
21. No less than 14×10 matrix; intuitive signal routing table, adjustable level at crossover points
22. No less than 16 presets;
23. Supports input and output channel LINK and grouping functions;
24. Input dynamic range no less than: 110dB
25. Output dynamic range no less than: 112dB
26. Frequency response range no less than 20~20kHz (±0.5dB);
27. THD+N: no less than -100dB @17dBu
