The  MT109-102 is 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 MT109-102 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 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.
