The NOVA 2001 digital audio matrix MTX2001
offers a unique modular design; developed from
the innovative idea of a matrix, each MTX2001 is
a complete 4 x 8 digital matrix. This configuration
allows complete flexibility in system design,
including full redundancy. In addition, hardware
and software changes are made easily and
quickly.
To increase the dimensions, it can be connected
to other identical boards (up to 16 in all), without
additional wiring. The input audio signal is first
converted to digital stream (CD audio quality), and
then to analogue.
No need for external wiring to
assemble or modify the matrix
Increased flexibility and reliability
Reduction of dissipated heat,
heightened noise immunity, EMIRFI compliance
System expansion requires fewer
modules; system produces very
high quality audio signals
(processed at CD-level quality).
The matrix can auto-reset, in case
of failure, and returns to the last
valid configuration
Each board is a complete 4 x 8
audio matrix without external
wiring required. Output disable
allows fully redundant
configuration
Real input equalization for each
audio channel delivers the best
intelligibility and quality from the
signal source
Some keys for the MTX2001 include independent
high and low tone controls for any input channel; a
chime generator; and audio filters to configure
modular systems, with no need to connect
auxiliary external devices.
The balanced outputs can be used as line drivers,
with high level and low distortion signals. As a
final point, it is possible to monitor each input or
output on any board.
The board is easily installed and managed by the
user. It is installed on the NOVA 2001
motherboard, powered by the NOVA 2001 PSU,
and controlled by the NOVA 2001 CPU via the
software user interface.
