DP48

DP48 is a cost effective 4inout digital audio processor, suitable for live show, fixed installation and many other applications. 

4 analog input and 8 analog output are processed by the powerful M716DSP. Besides the high performance 24bit AD/DA converter each channel features 30-band PEQ gain control RMS limiter and adjustable delay.

Each output provides maximum 7-band PEQ whose slope randes from 6 dBu / Octave to 48 dBu / Octave.

Each output can select peak compressor and adjustable delay.In addition, high and low pass filter is also available.
