Technical Note about the Audio Inputs

Since the audio inputs are unbalanced (single ended), the ground
reference of the source has to be the same as the matrix. Of course
the cable connecting the two is tying the grounds across but if there
are currents flowing in the ground it can create potential differences
that would manifest as noise. The quality of grounding at the audio
source and the matrix are important. For example if the input source is
a desktop PC, as long as the PC is properly grounded and the audio
cable length is not excessive, you can expect good results. On the
other hand if the input is a notebook PC running on battery, there is no
ground reference at the source so it gets its reference through the
audio (and video) cable connection to the matrix. This should also be
okay. However if it is plugged in through its external power brick, noise
can be induced. This is because most notebook power supplies do not
properly provide an AC ground path to the system ground (some only
have only 2 prong AC cords). The switching power supply circuit will
inject noise into the audio lines. In this case the solution may be to
attach a low resistance ground strap to the notebook. The other option
for eliminating the noise is to use a stereo audio Balun (or isolator).
The Balun essentially couples the audio through a transformer so the
audio grounds are isolated. Baluns can also cure noise pickup in long
cable runs.

2.1.2 AV inputs on units with RJ45

Two types of RJ45 input configurations may be possible. Please contact Hall
Research sales for availability and delivery information. The model number
designates the input either as:

JP (RJ45 with power) or

JA (RJ45 with Audio).

2.1.2.1 RJ45 input with Video and Power

The JP units are compatible with Hall Research’s Mini-Cat® series of senders.
The Matrix can also send power to one channel senders via the CAT5 cable so
that no external power supply would be needed. This is applicable to senders
with only 1 RJ45 output as listed in the following table.
