DESCRIPTION

The MediaMatrix® MM™-740
Mainframe is the heart of an
unprecedented digital audio system.
The system is based on an open

architecture that utilizes a system
controller and digital processing unit
(DPU) card and can be expanded with
one or more DPU cards employing four
(4) Motorola 56002 DSP chips. When
attached to the MM™-8830,
MM™-8840 or MM™-8848 Digital
Interface, it provides 8 inputs and
8 outputs. The maximum system
capacity is 128 total inputs and outputs.
The MediaMatrix MWare™ operating
software provides the user/designer the
ability to design, wire (in the soft
domain), and troubleshoot a complete
digital audio system. The user can then
control all the parameters of the system
or create custom panels, or even
devices, to provide solutions not
previously available.
The MWare™ operating software
provides system diagnostics, system
design, audio devices, and DSP
compiling features, which run under the
familiar Windows™ environment.
