Genesis™ Matrix Switches
2.2.1 AV outputs on standard unit
The video output connectors on the basic unit are HD15 female. These are
compatible with PC’s VGA video signal (RGBHV). The Matrix is also
compatible with YPbPr HDTV signals with the use of HD15 to 3 RCA adapter
cables.
The audio outputs of the matrix are balanced. So a + and a – are provided for each
side. There is also a ground connection available. If you are going to connect the
matrix output to a single-ended audio device (one with RCA or phono
connectors); then use the + of the left, + of the right, and ground. On the other
hand, if you will be connecting the output to professional audio gear it is best to
use the differential + and – (balanced) outputs of each side that offer immunity to
noise.

The balanced audio outputs are provided on detachable screw-terminals. Mating
connectors for all outputs are also provided.
Technical Note about Professional Audio Output
Matrices with Pro Audio option can individually adjust the audio levels
at each input. Additionally they can set all the outputs to “pro line-level”
of +4bBu. This is a global setting which boosts all the outputs to a high
line level.
2.2.2 AV outputs on units with RJ45
Currently there are three types of RJ45 output configurations possible. Please
contact Hall Research sales for availability and delivery information. The model
number designates the outputs either as:
‰
JP (video on RJ45 with power)
‰
JA (video on RJ45 with Audio)
‰
JR (video on RJ45 with RS-232 Serial)
Other RJ45 output configurations will be forthcoming (such as JRA video, audio,
and serial).
