The MT109-102 is a Stereo Audio Mixer Card designed for use with the MultiTasker. When installed in the Basic Enclosure (MT100-100), this card allows connection of up to three line level balanced or unbalanced microphone inputs.
Mixing of inputs is controlled via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the Basic Enclosure. The MT109-102 can accept balanced or unbalanced audio inputs and the output can be wired for either balanced or unbalanced audio output.
Through RS-232 control, the MT109-102 can be controlled to adjust signal level of each input in 32 steps. In addition the volume, treble, and bass of the output amplifier can be adjusted in 32 steps. All three inputs to the amplifier are mixing inputs and can be adjusted from 0db to –60db. Phantom power +12V can be connected to the microphone input using dip-switch located on the PCB.
