3.2 Recommended Input Wiring Methods

The following are the recommended
methods for connecting sources to the
Intelix VC Series mixer. The mixer input is
always balanced. From the following
drawings, choose the wiring method for your
input device (either balanced or unbalanced).
Balanced Source to Balanced Input
Shown is the normal wiring method for a
balanced source device. It has +6 dB gain
and excellent ground current and noise
rejection.
Balanced Source to Balanced Input
If the method above does not work in your
application, use the wiring shown. This
method solves certain ground loop
problems, having +6 dB gain and good noise
and ground loop rejection.
Unbalanced Source to Balanced Input
For an unbalanced source device, the draw-
ing shows the best wiring method. This
wiring provides a slight (+6 dB) boost, as
well as moderate noise and ground loop
rejection.
Unbalanced Source to Balanced Input
For an unbalanced source device, the draw-
ing shows an alternative wiring method.
Because the grounding of the minus input is
not to the mixer ground, this method does
not provide the +6 dB boost. Ground
current and noise rejection is good.
