CONNECTIONS
To connect the loudspeaker systems
to the receiver or amplifier, use two-
conductor insulated wire. Your JBL dealer
can recommend suitable cables, or you
can buy wire at most hardware or elec-
tronic stores. We recommend #16 AWG
wire as a minimum size.
use the bi-wiring feature, please read
that section of the manual for type of
speaker interconnect wire to use. If
your speakers are more than 30 feet
(10 m) from your receiver or amplifier, use
larger diameter wire. Connections are
made at the terminals located on the back
of the loudspeaker system. The terminals
accept bare wire or dual banana plugs,
either of which will provide easy, secure
connections.
Preparing the Hookup Wire
Carefully plan your wire lengths before
cutting any speaker wire. Be sure to allow
plenty of extra wire to help hide paths in
corners, along baseboards, etc.
1. First determine the wire length needed
between the most distant speaker and the
receiver or amplifier.
2. Now make the hookup wires for both
speakers this length, even if one loud-
speaker is much closer to your amplifier
than the other. This will help maintain
proper signal balance.
3. Strip off 3/8" of insulation from both
ends of each conductor.
4. Twist each set of thin wires into a
tightly-bunched spiral.
5. At this point you need to identify a
visual difference between the two conduc-
tors of each molded pair of speaker wire.
Differentiating marks can be a different
color wire (copper or "silver"); a strand
of yarn in one conductor; thin, raised ribs
on one part of the outer insulation; or a
printed "+" marking on one of the insula-
tors. It does not make any difference
which of the two strands of wire go to (+)
and (–) on the speakers and amplifier, as
long as both speakers are connected
identically. If using wire ends, unscrew the
colored nut on the terminal cup, insert the
wire end into the hole in the metal post,
then retighten the nut until the wire is

tightly secured. If using banana plugs,
simply insert the plug directly into the
holes on the top of the metal posts.
For each channel, the red terminal on the
loudspeaker should be connected to the
red or (+) loudspeaker connection terminal
on the receiver or amplifier, and the black
to the black or (–) speaker conection ter-
minal (see Fig. 3). Connecting the loud-
speakers in this manner ensures that they
will be in phase; that is, work together
rather than in opposition. Connecting the
loudspeakers out of phase will not dam-
age them, but will result in less bass and
poor imaging.

Hooking Up Multiple Sets of Speakers
If your receiver has two complete sets of
speaker terminals ("A" and "B"), it's possi-
ble to hook up an additional pair of speak-
ers for simultaneous sound in another
room. However, some speakers may not
be usable as a second pair if you want to
play two sets at once. Before hooking up
another set of speakers besides your
GHE Series, check the following:
1. Your receiver or amplifier minimum
load impedance. Impedance is always
expressed in ohms and can be found in
the owner's manual that came with your
unit. For example, the following are typical
entries in receiver/amplifier owner's
manuals:
A)100 watts RMS into 8 ohms, both chan-
nels driven, 20–20kHz with less than
0.02% THD.
