DPA-B series Digital Audio Processor

◆ 96kHz sampling rate, 32-bit DSP chip processing, 24 bit AD/DA conversion.
◆ The input processing section includes high cut, low cut, 8-parameter equalization, noise gate, gain, mute, phase, delay, linkage adjustment and other processing functions.
◆ The output processing section includes processing units such as frequency division, 9-parameter equalization, gain, mute, compression/limiter, phase, delay, and linkage adjustment.
◆ The PEQ gain, bandwidth, and frequency of all channels are continuously adjustable, and the types can be selected: parameter equalization, low frame filtering, elevated filtering, low cut filtering, elevated filtering, phase-shifting 1st order, phase-shifting 2nd order.
◆ All inputs and outputs can be freely allocated in a matrix format, and the name of each input/output channel can be changed.
◆ All input and output channels have independent phase curve adjustment functions. In the PEQ type, select phase shift 1st order for 180 degree curve adjustment, and phase shift 2nd order for 360 degree curve adjustment.
◆ All high cut and low cut filters and frequency dividers can be selected from the following types:
◆ Butterworth, Linquerelli, Bessel, with slopes ranging from -6dB/Oct to -48dB/Oct.
◆ The threshold, ratio, startup time, and recovery time of the compression/limiter for the output channel are continuously adjustable.
◆ All delay modules of input and output channels have a delay time of up to 680ms.
The parameter settings between any channel can be freely copied, and any channel can be adjusted through linkage.
◆ You can see the PEQ curve adjustment chart of all current input or output channels at any input or output channel.
◆ Built in test signal generator, with optional output modes including pink noise, white noise, and adjustable 20Hz-20kHz sine wave, and adjustable signal amplitude
◆ The front panel is equipped with input and output level indicator lights, USB control ports, 232&485 control ports on the rear panel, and Ethernet remote control ports. One click connection makes user operation easier and faster.
◆ 32 user presets, the overall machine status and each preset can be stored and called up separately.
◆ The ID setting function can cascade control 256 machines and also has password protection to make the device more secure.
