Peavey Miniframe 108nt, Miniframe 208nt Specifications

Description

The MediaMatrix Miniframe 208nt and
Miniframe 108nt are the most economical
of Peavey’s digital signal processing prod­ucts with an integrated CPU. Both are
software-based, integrated sound system
design, control, and hardware platform
that require only microphones and their
preamps, power amplifiers, and speakers
to provide a complete and working sys­tem. The Miniframe 208nt and Miniframe
108nt are based on an open architecture
that utilizes a modular computer main­frame including a power supply, a floppy
disk drive, a CD-ROM drive, and a system
controller board. The Miniframe 208nt
comes with two DPU boards, and the
Miniframe 108nt comes with one DPU
board. Fully loaded, the Miniframe 208nt
can provide all needed signal processing
for 64 audio input lines and 64 audio out­put lines, while the Miniframe 108nt
accommodates up to 32 audio input lines
and 32 output lines.

The Miniframe 208nt and Miniframe
108nt CPU is Intel

®

Pentium®III based or
equivalent, or better and the user’s control
and design interface GUI is Peavey’s
MWare™3.x running under Microsoft

®

Windows®2000 Professional. The MWare

3.x 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 Miniframe 208nt and Miniframe
108nt accommodate a DPU board that
employs Motorola

®

56002 80 MHz DSP
chips and provides signal processing for
up to 32 digital audio inputs and up to 32
digital audio outputs. The Miniframe 208nt
accommodates a maximum of two DPU
boards, while the Miniframe 108nt accom­modates one DPU board. 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-RJ is
the standard DPU board that interfaces to
the Peavey MM-8802 Break-out-Boxes
(BoBs). The Miniframe 208nt-aes inter­faces to AES/EBU standard digital signal
I/Os from the first DPU board. The
Miniframe 208nt-cn interfaces to the
Peavey CAB

™

Series CobraNet™bridges,
which transport audio and control via an
Ethernet network from the first DPU
board.
