1. 96KHz sampling frequency, 32 bit DSP processor, 24 bit A/D and D/A conversion 2. Provide USB and RS485 interfaces to connect to computers, making it convenient for different application needs, 3. It is very convenient, intuitive, and concise to directly use the functions of the panel and the coding wheel for function settings or connect to the computer for control through PC control 4. Both standalone and PC control software can store 20 types of user programs 5. Each input has 6 segments of PEQ, and outputs 6 segments of PEQ 6. 2 * 24 LCD green backlight display function setting 7. The slope of the variable high/low pass filter can be set, with Bessel and Butterworth set to 12dB, 18dB, and 24dB per octave, and Linkwitz Reiley set to 2dB, 18dB, 24dB, 36dB, and 48dB per octave 8. The parameters of the high/low pass filter can be independently controlled and muted, with a maximum delay of up to 100MS. The delay unit can be selected in milliseconds (MS), meters (M), and feet (FT). The output channels can also control gain, voltage limit, and select input channel signals. Multiple output channels can be selected simultaneously to synchronize and adjust all parameters
