Peavey MEDIAMATRIX MM-760NT DATASHEET

Description

The MediaMatrix¨MM-760nt

Mainframe is the workhorse of PeaveyÕs
digital signal processing product line. It is
a software-based, integrated sound
system design, control, and hardware
platform that requires only microphones
and their preamps, power amplifiers, and
speakers to provide a complete and
working system. The MM-760nt
Mainframe is based on an open
architecture that utilizes a modular
computer mainframe including a power
supply, a floppy-disk drive, a CD ROM
drive, a system controller board, and up to
four digital signal processing boards.
Fully loaded, the system can provide all
needed line-level signal processing for
128 audio input lines and 128 audio
output lines.

The MM-760nt CPU is Intel Pentium

II

¨

-equivalent based or better, and the
userÕs control and design interface GUI is
PeaveyÕs MWare

ª

3.0 running under
Microsoft¨Windows NT 4.0¨. The
MediaMatrix MWareª3.0 software
provides the user/designer the ability to
design, wire, operate, control, and
troubleshoot a complete digital audio
system in the software domain. The
user/designer can create control panels

and devices to provide solutions not
possible on other DSP audio platforms.

The MM-760nt Mainframe
accommodates three types of DPU
boards. Each of these DPU board types
employs four Motorola

¨

56002 DSP chips
and provides signal processing for up to
32 digital audio inputs and up to 32 digital
audio outputs. Due to extremely efficient
code, an exceptional amount of
processing can be accomplished while
maintaining double-precision DSP filtering
on each DPU board. The MM-DSP is the
standard DPU board that interfaces to the
Peavey MM-8800ªSeries Break-out­Boxes (BoBÕs). The MM-DSP-AES is the
DPU board that interfaces to AES/EBU
standard digital signal I/Os. The MM-DSP­CN interfaces to the Peavey CABªSeries
CobraNetªbridges, which transport audio
and control via an Ethernet network.
