Connecting external devices to the input signals

of the auxiliary I/O interface

You can connect a wide variety of external devices to the input signals of the
Matrox 4Sight X auxiliary I/O interface.
Each of the input signals of Matrox 4Sight X is TTL-compatible. The
Matrox 4Sight X input signals will be enabled (on) when the voltage applied is
greater than 2 V. The Matrox 4Sight X input signals will be disabled (off ) when
voltage is lower than 0.8 V.
Each of the input signals of Matrox 4Sight X is able to accept input voltages
ranging from 0 V to 24 V.
Connecting a stereo audio device
You can connect a stereo audio device to the audio input and output connectors,
using a 1/8" mini audio input/output plug. The audio interface is only designed
for line input/output operations. Since there is no output amplifier or input
preamplifier, the interface does not support speakers or microphones.
