SPECIFICATIONS
The MediaMatrix MM-760nt Mainframe
signal processor shall be a software-
based, integrated sound system design,
control, and hardware platform that
requires only microphones, microphone
preamps, power amplifiers, and speakers
to provide a complete and working
system. It shall be 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. The
MM-760nt Mainframe system shall provide
all needed line-level signal processing for
up to 128 audio input lines and 128 audio
output lines. Systems of lesser capacity
shall not be acceptable.
The MM-760nt Mainframe systemÕs CPU
shall be Intel Pentium II-based, or
equivalent, or better and the userÕs control
and design interface GUI shall be
PeaveyÕs MWare 3.0 running under
Microsoft Windows NT 4.0. The MM-760nt
Mainframe systemÕs software must
provide the ability to design, wire, operate,
control, and troubleshoot a complete
digital audio system in the software
domain. It shall allow the creation of
custom control panels and devices to
provide unique solutions not possible on
other DSP audio platforms. Additionally, it
shall allow third-party control of virtually
any adjustable parameter in the system
design. Systems not providing the above
capabilities and not operating under
Microsoft Windows NT 4.0Õs robust and
stable operating system shall not be
acceptable.
The MM-760nt Mainframe shall
accommodate three types of DPU boards:
digital audio boards accommodating A/D
and D/A converted signals, AES/EBU
standard digital audio signal boards; and
digital audio boards for CobraNet bridges
to Ethernet networked audio paths. Each
of these DPU board types shall provide
signal processing for 32 digital audio
inputs and 32 digital audio outputs.
Systems not accommodating various
digital audio DPU boards shall not be
acceptable.
The MM-760nt Mainframe system shall
have a CPU that is an Intel Pentium IIâ
350 MHz with 512 kB of cache and 64 MB
of RAM or equivalent, or better. It shall
have a 1.44 MB FDD, a 32X CD ROM
drive, and a 10/100BaseT fast Ethernet
interface board. Video shall be True color
PCI video with 4 MB of video RAM and
selectable resolution from 640 x 480 to
1,600 x 1,200, plus refresh rates from
43 Hz to 200 Hz. The MM-760nt
Mainframe shall have a 4.2 GB HDD. It
shall also have a passive backplane that
enables the digital audio to function during
CPU failure and a PIC/MG CPU slot for
easy board swapping. The backplane shall
have (4) PCI slots and (10) ISA slots to
enable maximum flexibility in system
configuration. Systems of lesser CPU and
video capabilities, or lacking the above
drives or passive backplane and its
flexible capacity shall not be acceptable.
The MM-760nt Mainframe shall
accommodate up to (4) audio DPU
boards. Each board shall provide digital
audio signal processing for 32 input
channels and 32 output channels. A 256-
channel digital audio bus shall allow
processing resources to be shared
between DPU boards and DSP chips.
Systems using hardware restricted digital
audio paths shall not be acceptable.
The MM-760nt Mainframe system shall
operate under the Microsoft Windows NT
4.0 operating system for stable operation
and increased network access security.
The sound system design, control and
diagnostics software shall be Peavey
MWare 3.0, which allows the creation of
custom control panels and devices to
provide unique solutions not possible on
other DSP audio platforms.
The virtual audio devices available for
sound system creation shall include the
following:
¥ AmpWare
amplifier control and
monitoring functions
¥ Automatic mixers
from 2 to 32 input
channels with direct outputs and
linking
¥
AES
digital audio input and
output ports and level controls
capability
¥ Bitmaps

¥ BoBÕs
(Break-out-Boxes) analog input
and output ports and level controls,
with control ports for virtually any
system control parameter
¥ Blocks
: a graphic object that contains
a child window with a sub-system or
sub-function, etc.
¥ Bump panels
: a graphic object for a
control area, label, message, etc.
¥ CABÕs
: (CobraNet Audio BoBÕs)
Ethernet audio input and output ports
and level controls, with control ports
for virtually any system control
parameter
¥ Comments
: a text entry area to type
in any type of note or comment for
explanation or clarification
¥ Control modifiers
to limit the range of
controls
¥ Crossover Networks
