ABOUT YOUR MT110-103 2
MT110-103
8X8 Mono Audio Matrix Switcher
The MT110-103 is a Balanced Audio Matrix
Switching Card. This card allows any input to be
independently switched to any or all of the outputs.
All inputs and outputs can be wired for unbalanced
audio, or they can be wired for balanced audio
allowing longer cable runs and superior noise
resistance. Additionally, the MT110-103 has
variable gain for each output.
As a “transparent” distribution amplifier, this card
utilizes AC coupling on its 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 MultiTasker enclosure or from the keys
programmed on the front panel of the MultiTasker.
Each card uses two slots in a MultiTasker
enclosure, and all input and output connections are
accomplished via captive-screw terminal blocks.
Although designated as an 8x8 matrix switcher, the
MT110-103 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 a 4x4 stereo audio matrix.
The HelpInside™ feature allows programmers to
have access to command structures and control of
the MT110-103 from any terminal using the [HELP]
command. In conjunction with ALTINEX’s unique
command structure, HelpInside™ provides
easier-than-ever control of MultiTasker cards with
simple keyboard commands. No typing of long
keyboard strings is necessary.
