Figures
6a and b show the use of 2-conductor shielded
cable and either
3-
or 2-cir-
cuit
plugs
with unbalanced
loads; like 3a and b, this often is useful for combatting
RFI
with unbalanced loads.

Sidechain hookups
The sidechain inputs are unbalanced. They’ll
work with balanced
and unbalanced
sources, but will unbalance a balanced output.
Figure
7a
shows the
connection of an
unbalanced signal source to either sidechain
input jack; a 2-circuit plug is
used since there are only two connections
to make.
If
a
3-circuit plug is used, either leave the
ring unconnected or connect it to the shield.
Figure 7b shows the
c<mnection of a balanced
source to either sidechain input. Most
balanced sources will work
without the dotted connection between
the (-) output and
grourKi
(this is true for "active-balanced"
outputs
and
"ground-referenced" outputs). How-
ever,
some sources require
the dotted connections shown
—
"transformer-isolated"
bal-
anced
outputs. We
recommend making
this connection only if necessary for
your instal-
lation, because some active
balanced and ground-referenced
outputs may be damaged
by
doing so. Note that a
2-circuit plug is used here; follow
the instructions above if
a 3-cir-
cuit plug must be employed.
