Product Introduction:
Audio Matrix Processor
  • features



    ⊙ Up to 400MHz, 32-bit floating point operation, 48KHz sampling, high performance 24bitA/D, D/A chip;

    ⊙65K color 5吋 color TFT LCD screen, 800x480 resolution, Chinese and English menu operation, the display content is more comprehensive and intuitive;

    ⊙16-channel line/microphone LINE/MIC input, using professional top-level high-dynamic vocal input circuit (0/-40dB independent sensitivity adjustment), the sound quality is unusual;

    ⊙ Input each independent 48V phantom power, with 5-band parametric equalization, expansion, dynamic compression, feedback suppression, high and low pass adjustment, mute and other functions, support the automatic gain of each input, effectively improve the quality of microphone pickup;

    ⊙Each input has an automatic mixing setting. When the highest level microphone speaks, other microphones are automatically attenuated or muted. The chairman microphone can set multiple levels of venue control easily and easily.

    ⊙ 16*8 audio matrix adjustment distribution, each output input mixing ratio can be adjusted separately;

    ⊙8 main output, each output has 5 sections of parameter equalization, gain, high and low pass, limit, delay, phase, mute and other audio adjustment functions;

    ⊙The speaker volume can be attenuated in the vicinity of the speaking microphone to further expand the sound reinforcement gain, and the conference sound reinforcement is clearer and more natural;

    ⊙ Support iPad, wireless wifi control through Apple control software;

    ⊙ Support multiple devices in parallel, expand the input and output channels, and adopt standard professional-grade multi-function interface, which is simple and reliable;

    ⊙ The panel lock function prevents misoperation.


    ⊙The host adopts the world-famous media matrix audio processing algorithm. The host set has anti-interference, no howling, and other core algorithm technologies to support 24 hours of uninterrupted work;

    ⊙ can work in WindowsXP/Windows7/Windows8 system environment;

    ⊙8 way\12 way\16 way balanced microphone/line input, using bare wire interface terminal;

    ⊙8 way\12 way\16 way balanced output, using bare wire interface terminal;

    ⊙48kHz A/D, D/A conversion sampling rate;

    ⊙ Dual-core high-speed DSP processing chip TI OMAPL138BZWT3 processing core;

    ⊙High-precision input sensitivity adjustment, total 21 steps, step size 3dB, maximum input gain 60dB;

    ⊙ Input per channel: preamplifier, signal generator, expander, compressor, 5-band parametric equalization, automatic mixing console;

    ⊙ Output per channel: speaker manager (8-band parametric equalizer, delay, divider, high-low-pass filter, limiter);

    ⊙ Built-in (AEC) adaptive echo cancellation, (AFC) adaptive feedback cancellation;

    ⊙ full-featured component matrix mixing function;

    ⊙RS-485 supports automatic camera tracking function to easily realize video conference;

    ⊙ RS-232 bidirectional serial control interface; can control other external devices such as video matrix, camera and other RS-232 devices, or receive third-party RS-232 control.

    ⊙ Support multiple sets of scene preset functions, user-friendly operation software interface;

    ⊙ Phantom power (per input) +48VDC10mA.

DM20new version update step


1) Copy the compressed package to the USB flash drive (note that you don't need to decompress it, it is best to format the USB flash drive first)


2) Insert the USB flash drive into any USB port of the mixer, and click “SETUP” on the mixer panel → “Maintenance” → “Update from USB” in the screen


Follow the prompts to complete the installation steps.
