2 MT109-100 8-In 1-Out Stereo Audio Switcher Card The MT109-100 is 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 MT109-100 can accept only unbalanced audio inputs, the output 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 special 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.
