All-in-one Wireless Digital Processor
DSP-4800 is an all-in-one digital processor with 4 inputs and 8 outputs. The unit uses a 32-bit high-precision floating point and has a sampling frequency of 96Khz that reduces distortion. The processor can be controlled via USB or LAN, with the possibility of joining up to 250 devices. DSP-4800 comes with XLR-3 input and output connectors and is ideal for fixed installations, being able to equalize, limit, filter and delay the signal of its 8 outputs in an easy and fast way.
