Paulkitson DA48 professional digital audio processor 4 in 8 out DSP stage equipment effector with FIR speaker management system

The DA-48 series uses ADI's latest fourth-generation SHARC processor ADSP21489 Built-in routing/gain/delay/compression/limiter/mute/equalizer/high-low-pass filter/all-pass filter and phase and many other conventional audio algorithms. In addition, the following personalized functions are added, and each function is completely turned off or on independently.

● 96kHz/192kHz sampling rate switching, 32-bit400MHzDSP processor, 24-bitAD/DA conversion.
● The input processing part includes 3 DEQ, 12 PEQ, FIR filter, noise gate, gain, mute, phase, delay and other processing functions.
● The output processing part includes FIR and IIR frequency division filters, 16 parameter equalization, gain, mute, compressor, peak limiter, phase, delay, linkage adjustment and other processing units.

● The gain, bandwidth and frequency of PEQ of all channels can be continuously adjusted, and the types can be selected: parameter equalization, low frame filter, overhead filter, low cut filter, overhead filter, phase shift 1st order, phase shift 2nd order.
● The gain, bandwidth, frequency and type of DEQ of all input channels are continuously adjustable, and the threshold, ratio, start time and recovery time of dynamic processing are continuously adjustable.
● All input and output channels are equipped with independent phase curve adjustment function. In the PEQ type, the first phase shift is 180 degree curve adjustment, and the second phase shift is 360 degree curve adjustment.
● The type of IIR frequency division filter can be selected: Butterworth, Ningke, Bessel, and the slope is from - 6dB/Oct to - 48dB/Oct.
● FIR frequency division filter: the number of sampling points is between 256 and 512, with multiple types of options, and the cut-off frequency is continuously adjustable from 20 to 20 KHz.
● Input channel noise gate threshold, start time, recovery time, and hold time are continuously adjustable, and the proportion of noise gate is independently adjustable.
● The compressor threshold, soft inflection point, ratio, start time and recovery time of the output channel are continuously adjustable. Moreover, the output has an independent peak limiter function, and the threshold, start time and recovery time are continuously adjustable.
● The delay module of all input and output channels has a delay time of up to 1200ms.
● The front panel is equipped with 2-inch LCD true color display, external WiFi interface and USB port. The rear panel has RS485 interface, which can be connected to the third party central control system, and can connect up to 250 devices.
● 30 user presets, each preset can be stored and called separately, and the parameters of the whole machine can be uploaded and downloaded. The ID setting function can cascade control 255 machines. The panel also has password protection function to make the device more secure.
