8CH DSP with 2X150W digital power amplifier

Products Introduce:

This product is an integrated dual-channel 150W digital audio processing device. It adopts advanced DSP processing technology, has a new algorithm of automatic mixing, feedback elimination, etc., and has a built-in two-channel digital power amplifier module, which has a more significant energy efficiency ratio, and also has a good performance in overload protection and distortion control. Various practical problems, in conjunction with other audio products of the company, can meet the application needs of more scenarios。Support RS232 control port with power supply. The latest Feedback Cancellation (AFC), Echo Cancellation (AEC), and Noise Cancellation (ANC) algorithms are optional


Main Feature:
1. Comprehensive matrix mixing function, 24bit/48KHz sampling frequency, high-performance A/D D/A converter and 32-bit floating-point DSP processor;
2. DSP audio processing, built-in automatic mixing console, including mixing and automatic mixing functions, and also has the function of mixing component control, and also has feedback cancellation, echo cancellation, and noise cancellation; the echo path length can be set to support The maximum echo tailing is as high as 512ms, which is suitable for use in various large, medium and small conference rooms; the built-in noise suppression algorithm can eliminate the additional noise in the noise environment; it can quickly track the change of the feedback path, so that the ability of howling suppression is greatly improved Enhanced; the microphone sound transmission gain is increased by no less than 6dB; the noise suppression reaches -30 dB, and the voice is completely distortion-free; the non-stationary noise can be processed, and the noise change can be quickly tracked;
3. Input each channel: preamplifier, signal generator, expander, compressor, 5-band parametric equalization;
4. Output each channel: 31-segment graphic equalizer, delayer, frequency divider, limiter;
5. Integrated design of audio processing and power amplifier output;
6. Support Ducker dodger, SPL automatic environmental noise compensation
8. Test signal generator, sine wave, pink noise, white noise, optional frequency and level;
9. Input phase switch, mute switch, phantom power switch;
10. Output mute switch and phase switch for each channel;
11. Flexible switch between Chinese, Traditional and English;
12. One-click display of all functional modules;
13. Random storage of Chinese help documents and software;
14. Central control code is randomly generated; power-off automatic protection memory function; one-button reset function;
15. Channel copy, paste, joint control functions;
16. The same host allows 10 users to manage, and the user name can be set to Chinese;
17. The device name can be modified, and Chinese names are allowed;
18. Editable preset mode, new, delete, modify, one-key initialization, preset mode can be stored to the computer and one-key recovery;
19. The input and output channels can independently set the color, and one-key recovery switch;
20. Built-in camera tracking function, compatible with VISCA, PELCO-D, PELCO-P three control protocols, and supports custom commands;
21. Convenient and fast webpage control: built-in webpage controller, which can be quickly operated on Windows, Android, iOS and other platforms;
22.Enternet multi-purpose data transmission and control port, which can support real-time management of single and multiple devices;
23. Intuitive image, simple and easy-to-understand graphical software control interface, bringing customers fast and real-time operation experience;
24. The device does not need a CD, and it has its own installation software. One device is for one software version, which solves the troubles caused by the loss of the installation CD and the confusion of multiple software versions;
25. With its own B/S architecture server, accessed through a web browser, it can realize channel control and scene selection functions, and directly provide download links for PC clients and platform components.
26. The expandable USB interface can not only realize the device upgrade function, but also the USB music playback and recording function;
27. Configure bidirectional RS232 interface and standard Ethernet control interface;
28. Support open udp, http control protocols. Open related protocol documents
29. Support 8~100 groups of scene preset functions;
30. Intuitive, graphical software control interface, can work in XP/Windows7, 8, 10 and other system environments.
