Audio Input Connections
Line-Level Input Connection
Proper wiring between the signal
source, any other components in
the system and the GTS100x will
help to keep noise levels in the
system low. Use high-quality,
low-capacitance shielded wire.
Keep the wire as short as possi-
ble. Do not splice shielded wires
together. Do not run audio signal
wires alongside power wires
either for the amp or the vehi-
cle’s standard power wires. When
wires are run for long distances,
separate the audio signal wires
from power supply wires or vehi-
cle wiring harnesses as much as
possible. When signal wires and
power wires must cross, try to
keep them perpendicular. Avoid
routing any wires near acces-
sories such as ignition control
NOTE: The GTS100x has a built-
in 80Hz low-pass (subwoofer)
crossover and a 100Hz high-pass
(satellite) crossover. Be sure the
crossover switch is properly set
for the chosen system configura-
tion (see the “Typical Applica-
tions” section on page 8 for
suggestions). If you have any
questions about how to set this
switch, contact your local
JBL dealer.
modules, tachometers, fuel
pumps or fan motors.
The line-level inputs of the
GTS100x accept standard phono
plugs (also called RCA plugs).
The outputs of most head units,
equalizers or crossovers also
accept RCA connectors. If
another type of connector is used,
adapters or special cables may
be needed. Proper wire and
connectors can be obtained from
any JBL authorized installation
specialist.
Input-Mode Switch
This switch is set according to
the number of input channels
connected to the amplifier and
the desired mode of operation.
See diagrams on pages 8 and 9
and the descriptions below for
options.
Standard Operation – When using
the GTS100x as a conventional
stereo amplifier, simply connect
the preamp-level source outputs
directly to the two gold RCA con-
nectors or connect the head unit
speaker outputs to the speaker-
level inputs with the input mode
switch set to “Stereo.” When
using two sources, both the
speaker and preamp-level inputs
may be used simultaneously. Be
sure to maintain left and right
channel consistency.
