ABOUT YOUR MT110-101/103 2

The MT110-101/103is a Balanced Audio Matrix Switching Card. This card allows any input to be independently switched to any of the outputs. All inputs and outputs can be wired for unbalanced audio, or balanced audio allowing longer cable runs and superior noise resistance.

The MT110-101is an 8x8 audio matrix with a fixed gain of 0db. The MT110-103is an 8x8 audio matrix with variable gain for each output.

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 MultiTasker™ enclosure. Each card consumes 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 MT110-101/103can 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. The MT110-101is a standard matrix switcher, whereas the MT110-103has individual volume trim control on each output.

The HelpInside™ feature allows programmers to have access to command structures and control of the MT110-101/103from 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.
