MT108-103
1-In, 4-Out Balanced Stereo Audio DA
The MT108-103 is a Stereo, Audio Distribution
Amplifier Card that allows the connection of a
single stereo, audio source to four receiving
devices. All inputs and outputs are balanced,
allowing longer cable runs and superior noise
reduction.
As a “transparent” distribution amplifier, this card
utilizes AC coupling on its input for ideal signal
transfer characteristics. The power indicator on the
card doubles as a signal detection indicator,
allowing easy troubleshooting in complex
configurations. Each card requires only a single slot
in the MultiTasker enclosure.
The MT108-103 also has the ability to turn its
outputs on or off independently using RS-232
commands sent to the MultiTasker from a control
system or from the enclosure’s front panel keys.
