DT-88DS Digital Feedback Suppressor

Product function parameters:
1. Equipped with OLED screen to display channel status, device IP address, and version number.
2.8 balanced microphone/line inputs, with 48V phantom power soft switch
3. Input gain 6dB step, no less than 9 gears; suitable for MIC and LINE levels
4.8 balanced line outputs
5.*The audio processor can be connected to the network, and mobile phones, tablets, and computers can control the audio processor through wired or wireless networks.
6.* Control the microphone volume, turn on and mute the microphone, and adjust the volume in real time through a mobile phone or tablet according to different speakers without having to go to the cabinet to ensure the continuity of the meeting.
7.* You can adjust the balance, pressure limit, and feedback of the microphone and music, and check the status of each channel at any time.
8. The audio processor has a built-in one-in and one-out sound card, supporting music playback, recording and soft video conferencing (such as ZOOM, Tencent Conference, DingTalk Conference, etc.).
9.*The computer is connected to the processor through a USB cable for music playback without the need to connect other cables.
10.*The computer is connected to the processor through a USB cable, and the conference can be recorded. You can choose a single channel, several channels or all audio channels.
11. Built-in programmable central control function, supports 1 channel 232 and UDP interface, and can be connected to 8 channels 232 expander.
12.* It can control the power supply, signal switching, environment control, audio, etc. in the system as a whole, and realize the functions required to start the system with one click.
13.*Support user-customized operation interfaces for Android and Apple, and support up to 30 devices managed by the same interface;
14.* Automatic gain control AGC ensures that the output volume of the sound system is stable and does not affect the volume in the audience area caused by the speaker being far or near the microphone.
