Each section can be selected for Bessel, Schaeffer. The slope of the filter is from 6dB / Oct to 48dB / Oct, including filters such as Butterworth, Bessel, Linquitz-Rayleigh

Each output has a high-precision and omnidirectional adjustable peak limiter and RMS limiter.

Input channel adjustable delay time up to 900ms, the output channel adjustable delay time up to 340ms

Computer network connection: each output channel can be directly connected with the computer / network, the rear panel of the USB interface, and computer communication, can also be used RS485 / TCPIP connected to the computer, through the remote PC software to set up the machine, monitoring and control.

Control: The front panel has an LCD display window, the knob button can be the function of the machine operation, the front panel of each channel has seven lights, used to display the output level or display pressure limit.
