Utilizing advanced dual-core DSP technology, it supports 64-bit floating-point operations. The ADC part employs a 768Khz/32-bit high-performance audio converter. All algorithms are processed by a pair of 500MHz high-performance DSPs. Digital processing includes: gain, polarity conversion, dynamic equalizer, graphic equalizer, parametric equalizer, shelving filter, time delay, frequency division, compression and signal routing. All inputs and outputs are balanced differential amplification, enhancing the signal's anti-interference ability and signal integrity. 

By adopting the latest FIR digital filter design, low-pass, high-pass, band-pass and band-stop filters can be designed, which can largely achieve the extraction of the required signals and the suppression of the unwanted ones. 

All audio interfaces use standard XLR (Cardioid) connectors. 

It can store up to 32 preset programs. This feature is convenient for users to save and recall them at any time. 

The input equalizer features 15 parametric equalization bands; 5 dynamic equalization bands; and 31 graphic equalization bands. It can largely meet various audio mixing requirements.
