DSP-4800 is an all-in-one digital processor with 4 inputs and 8 outputs. The unit uses a high precision 32 bit floating point and 96Khz sampling rate that greatly reduces distortion. You can control the processor via USB or LAN with the possibility of linking up to 250 devices. DSP-4800 ships with XLR input and output connectors.
