MATRIX EXPANDER
LINE MIXER
X-Matrix is a 12 X 2 matrix mixer. It's primary application is
to add additional matrix mixes to the X-VCA console. It can
also be used as a stand-alone matrix mixer. As a companion
piece to the X-VCA console, it provides the facilities to create
additional mixes from the eight Sub groups and the Left, Right
and Mono mix buses. In both applications, multiple units can
be daisy-chained, offering almost unlimited expansion capabili-
ties.
Each X-Matrix can accept 12 line inputs (via multi-pin connec-
tor) from the X-VCA or from 1/4" TRS line input jacks, and
generates 2 outputs which include insets, level adjustment and
muting capabilities. The outputs appear on balanced XLR's
mounted on the rear panel.
Expansion, applications and quality X-Matrix may be
expanded both horizontally and vertically, turning X-Matrix on
its own into a very versatile mixing system for specialized
applications, or where additional matrixes or auxiliary mixes
need to be added to any console.
The X-Matrix has all the flexibility, sonic purity and rock solid
reliability common with all Crest Audio mixing console prod-
ucts. While it is intended to be used as an add-on accessory
to the X-VCA console, it's flexibility allows it to be used in a
wide variety of applications such as submixing, recording,
broadcast, and monitor mixing.
Powering for the X-Matrix Power is derived directly
from the console for up to 4 units. This configuration enables
a basic X-VCA to generate 12x12 matrix outputs. The X-
VCA console acts as the power supply, talkback, and solo and
headphone system for the added-on X-Matrix units. With
the addition of an optional power supply, virtually unlimited
matrixes may be added to the X-VCA. The external power
supply unit contains headphone and talkback facilities allowing
the X-Matrix to be used as a flexible, full featured stand-alone
unit.
