MT110-101/103
8-in 8-out Mono Audio Matrix
Switcher Card
The MT110-101/103 is a Balanced Audio Matrix
Switching Card designed for use with the Multi-
Tasker system. When installed in a Multi-
Tasker, this card allows any input to be
independently switched to any of the outputs. All
inputs and outputs can be wired for unbalanced or
balanced audio, allowing longer cable runs and
superior noise resistance.
The MT110-101 is an 8x8 audio matrix with fixed
gain of 0db. The MT110-103 is an 8x8 audio matrix
with variable gain for each input.
As “transparent” distribution amplifiers, these cards
utilize AC coupling on their inputs for ideal signal
transfer characteristics. Switching is controlled
with easy-to-use ASCII commands from a control
system or computer connected to the RS-232 port
of a Multi-Tasker™ enclosure. Each card
consumes two slots in a Multi-Tasker enclosure,
and all input and output connections are
accomplished via captive screw terminal blocks.
Although designated as an 8x8 matrix switcher, the
MT110-101/103 can be used in a variety of ways to
provide different capabilities. For example, one 8x8
card can handle mono audio while two 8x8 cards
handle stereo audio, or a single 8x8 card can be
used to create an 4x4 stereo audio matrix.
