ENGLISH VERSION
DSP-4800 is an all-in-one digital processor with 4 inputs
and 8 outputs. The unit uses a high precision 32 bit oat-
ing 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.
