P4800 SYSTEM PROCESSOR

DESCRIPTION

The P4800 S ystem Processor is a 4–input, 8–output d igital audio processor. It p erforms all the n ecessary functions between t h e
mixers a nd t he p ower amplifiers i n small t o medium s ized s ound systems. U sing the P 4800’ s d rag–and–drop Graphical U ser I nter ­face, processors c an be placed a nywhere in the s ignal path. The 4 –by–8 matrix mixer a llows any or a ll inputs to b e routed to any
or all outputs with additional controls for levels and polarity. The P4800 can store up to 128 configurations that can be recalled
using simple contact closures, MIDI, or RS232 commands.

SOFTWARE FEATURES

The primary interface f or t he P4800 i s a Windows–based s oft­ware program t hat mimics t he functional b lock diagrams u sed
in sound system d esign. Unlike m any o ther DSP p roducts t hat
constrict design freedom with preset templates, the process­ing blocks i n the P4800 c an be applied i n any order, to a ny in­put or output. Processing blocks c an be copied a nd pasted to
duplicate processors across m ultiple channels. They c an a l so
be linked for more efficient stereo or global control.

With the P4800, the entire system can b e designed, saved to
disk, and loaded at t he j ob site f or easy s et up. T he P 4800 also
allows r eal–time d esign changes, s o processing blocks can be
added, r emoved o r changed d uring system tuning. T he securi­ty options a llow complete lock of the system t o prevent unde­sired tampering, or to restrict user access to certain parts of
the system.
