Features

1. Adopt the fourth generation DSP chip of American ADI Company——ADSP-21489  400MHz 32/40-bit floating-point DSP

Adopt professional grade 24-bit A/D and D /A conversion chip, ELNA  electrolytic capacitors and other world-renowned audio equipment, the sound is  pleasant to the ear;

2, 4 groups of optional music signal input , 2 groups of analog, one group of  optical fiber and coaxial, the input gain is adjustable, the analog input  sensitivity is adjustable in two levels,

The processing of the music channel includes: 20-band parametric equalization,  3-band dynamic EQ, high and low pass and main channel music high pass  independent settings, noise gate, compressor, exciter. Among them, D7 model  optical fiber and coaxial input support AC3/DTS 5.1 decoding (when set to  decoding mode)

3, 2 groups of 4 channels Microphone input (front 2 and rear 2), two  independent input gain control potentiometers on the front panel.

The processing of the microphone channel includes: 25-band parametric  equalization, high and low pass, 5-level howling suppression, noise gate,  compressor, exciter

Processing of the effect channel Including: reverb + echo A + echo B, each  effect is independent 7-band parametric equalization, and the internal  parameters can be set flexibly;

4, 6-way XLR balanced output, two sets of stereo recording and surround  output, all outputs can flexibly set the microphone direct sound, effect, and  music ratio.

The processing of the output channel includes: 10-band parametric  equalization, high and low pass, compressor, delayer

The output channel can store three modes of singing, dancing and decoding ,  can be switched flexibly and quickly after setting

5. Provide USB and RS232 interfaces, reserved WIFI/BT control interface, can  be connected to a computer, provide Remote control and infrared control

6, 2*20 character LCD display, function keys and dials on the panel for  flexible and quick function settings

7. Provide 21 groups of preset storage space, users can edit 16 groups of  data, and easily import and export through PC software
