4-in 4-out Stereo Audio Line Driver
Cards
The MT108-104/(105) is a Stereo Audio Line
Driver Card designed for use with the Multi-
Tasker

system. When installed in a Multi-
Tasker

, this card allows the connection of four
stereo audio sources to four receiving devices,
which can include cassette recorders, mixers,
and/or amplifiers for sound reinforcement systems.
These cards are ideal for distributing audio to
recording devices in dubbing racks using simple
off-the-shelf cables. As an example, the MT108-
104/(105) can distribute audio to four cassette
recorders or it can handle the audio portion of A/V
distribution to four VCRs.
As a “transparent” line driver, these cards utilize
AC coupling on their inputs for ideal signal transfer
characteristics. The power indicator on the card is
a red LED indicating the board has power applied.
These cards consume one slot each.
