XLR Balanced Wiring Guide
CONNECTING THE S•com plus
The are several ways to interface the S•com plus to support a variety of applications. The S•com plus features
servo-balanced inputs and outputs, so connecting balanced and unbalanced signals is possible without any sig-
nal loss. The S•com plus can be used on a single instrument by connecting to a channel’s insert points, or on an
entire mix "in-line" between a mixer’s outputs and a power amp or equalizer.
INSERT POINTS
Many mixers today provide channel and bus or group inserts. Insert points are input and output patch points that
interrupt the channel or bus signal so that external processors can be connected. Channel insert points are ideal
for connecting to when using the S•com plus to process a single channel like a vocal, bass or guitar. Bus insert
points are ideal for compressing groups of instruments like vocals, strings or drums. If you are connecting to a
channel’s insert points, you may have a single TRS jack for Send & Return. In this case, use an Insert "Y" Cable
that configured like the one in the wiring diagram below.
