    24-bit high-end converter plus 96kHz sampling frequency, with excellent sound quality performance, 2-channel input and 6-channel output perfect mixing matrix speaker processor, first-class DSP processing technology, each input channel has 30-segment equalization filter, and is equipped with 3 all-pass filters, and each output channel has 7-segment equalization filter, each input and output filter can be selected as bell, shover, high/low pass, band pass filter and notch filter;

    Each output channel has an accurate dynamic range controller, which is operated by a pressure limit according to the RMS value of the pressure limit input;

    Each input channel adjustable delay time up to 480ms, each output channel adjustable delay up to 270ms;

    In addition to communicating directly with a computer via USB on the backboard, the machine can also be set up, monitored and controlled via remote PC software via an RS485 connected computer.
