DSP-3 | DSP-4 | DSP-30
The DSP-3 and DSP-4 are compact, 2-channel signal
processing modules that can plug into the back of
most DataPort-equipped QSC amps to conserve rack
space and simplify interconnection. They can also be
mounted into a DPX-4 remote rack mounting bracket
for use as a standalone, rack-mounted processing unit.
The DSP-3/4 are professional audio processors
featuring 24-bit/48 kHz A/D converters, balanced
inputs, and presets that can be selected without
turn-on pops or zipper noise. Their processing power
is dynamically allocated, removing the limitations
imposed by fixed signal-chain designs. The power and
flexibility of the DSP-3/4 eliminates expensive
outboard DSP gear, which reduces cost and installation
time and simplifies setup.
The DSP-30 is a rack-mount device almost identical to
the DSP-3. The other main differences between these
three devices are their dynamic range specifications
and output connectors.
