Peavey MEDIAMATRIX MM-900NT DATASHEET

Description

The MediaMatrix®MM-900nt Series
Mainframe is the flagship of Peavey’s
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 900 Series
Mainframe is based on an open
architecture that utilizes a modular
computer mainframe including dual
redundant power supplies, a floppy-disk
drive, a CD ROM drive, a system
controller board, and up to eight digital
signal processing boards. Fully loaded,
the system can provide all needed line­level signal processing for 256 audio input
lines and 256 audio output lines. There
are two models in the 900 Series: the MM­980nt and the MM-960nt. The MM-980nt
includes dual, removable, mirrored
redundant hard disk drives. The MM-960nt
has a single hard disk drive.

The Series CPU is Intel Pentium II

®

-based,
and the user’s control and design interface
GUI is Peavey’s MWare

™

3.0 running

under Microsoft

®

Windows NT 4.0®. The
MediaMatrix MWare 3.0 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 900 Series 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-8800

™

Series Break-out­Boxes (BoB’s). The MM-DSP-AES
interfaces to AES/EBU standard digital
signal I/Os. The MM-DSP-CN interfaces to
the Peavey CAB

™

Series CobraNet

™

bridges, which transport audio and control
via an Ethernet network.
