MT109-100

8-In 1-Out Stereo Audio Switcher Card

The MT109-100is a Stereo Audio Switcher Card which 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 through easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker enclosure. While the MT109-100can accept only unbalanced audio inputs, the output can be wired for either balanced or unbalanced audio.

The MT109-100is primarily designed to utilize the inputs and output offered on the connector panel. However, it also offers a special feature that enables the MT109-100to 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 MT109-100cards 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.
