80 Appendix B: Technical reference
Audio input and audio output connectors
The audio input and audio output connectors are 3.5 mm TRS mini-jacks
designed to carry stereo audio. You can connect a stereo audio device to the audio
input and output connectors, using a 3.5 mm audio input/output 3.5 mm TRS
mini-jack plug. The audio interface is only designed for line-level input/output
operations. Since there is no output amplifier or input preamplifier, the interface
does not support unamplified speakers or microphones without a preamplifier.
DC power connector
The DC power connector is a terminal-block connector. It is shown below with
the single x3 mating connector attached to the chassis.
The positive (+) and negative (-) wire terminal slots must be connected for the
device to be powered.
Warning To ensure EMC conformity, connect the chassis ground pin of your Matrox 4Sight
EV6 unit to earth.
