Peavey MEDIAMATRIX MINIFRAME 108NT, MEDIAMATRIX MINIFRAME 208NT DATASHEET

Description

The MediaMatrix¨Miniframe 208nt and
Miniframe108nt are the most economical
of PeaveyÕs digital signal processing
products with an integrated CPU. Both are
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 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
line-level signal processing for 32 audio
input lines and 32 audio output lines, while
the Miniframe 108nt accommodates up to
16 audio input lines and 16 output lines.

The Miniframe 208nt and Miniframe
108nt CPU is Intel Pentium MMX

¨

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

¨

Lite running under

Microsoft

¨

Windows NT 4.0¨. The MWare
Lite 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 accomodate a DPU board that
employs Motorola

¨

56002 DSP chips and
provides signal processing for up to 16
digital audio inputs and up to 16 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 double­precision DSP filtering on each DPU
board. The MM-DSP is the standard DPU
board that interfaces to the Peavey
MM-8800ªSeries Break-out-Boxes
(BoBÕs).
