The MT109-100 is a Stereo Audio Switcher Card that allows the connection of 8 stereo audio sources to a single receiving device such as a cassette recorder, mixer, and/or amplifier for sound reinforcement.

Inputs are selected via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker enclosure. While the MT109-100 can accept only unbalanced audio inputs, the output is a balanced output that can be wired for either balanced or unbalanced audio.

The MT109-100 is primarily designed to utilize the inputs and output offered on the connector panel. However, it also offers a feature that enables the MT109-100 to send or receive stereo audio signals to or from another MT109-100.

This feature can be used in a variety of ways to expand the capabilities of the card. For example, two MT109-100 cards can be installed in the MultiTasker and the output of one can be routed to an input of the other, creating a 15-In, 1-Out switcher.
