MT109-102

3 in 1 out Audio Mixer Card

The MT109-102is a Stereo Audio Mixer Card. 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 controled via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker™ Basic Enclosure. The MT109-102can accept balanced or unbalanced audio inputs and the output can be wired for either balanced or unbalanced audio output.

Through RS-232 control, the MT109-102can be controlled to adjust the signal level of each input in 16 steps. In addition the volume, treble and bass of the output amplifier can be adjusted in 16 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 a dip-switch located on the PCB.
