Remote Turn-On Wire - JBL GTS100X Owner's Manual

• When multiple amplifiers are
16
installed in the system, it is
often best to ground all of the
amplifiers and signal processors
to the same point to prevent
noise pickup from a ground
loop. In some unusual installa-
tions the noise level will be
lower if the amplifier or ampli-
fiers are grounded to the same
point where the head unit is
grounded. Use of heavy gauge
wire for all grounding, even sig-
nal processors and head units,
can also help to minimize possi-
ble noise pickup.

Remote Turn-On Wire

(Blue with White Stripe)
Because the JBL GTS100x
includes Common Sense two-way
turn-on circuitry, you have two
options for remotely activating
the amplifier. When using the
speaker-level inputs with a head
unit that includes a BTL power
amp, it is not necessary to con-
nect the remote wire. The ampli-
fier will automatically activate
whenever you turn on the head
unit. If the head unit is not of the
high-power BTL type, Common
Sense will not work. You will need
to connect a remote wire as fol-
lows. If you are using the line-
level inputs, follow the remote
wire connections listed.
The remote power control sys-
tem turns the GTS100x off when
not in use to prevent discharging
of the vehicle's battery. When
12 volts is applied to the remote
+
wire, the amplifier is turned on.
A red LED on the end panel of
the amplifier lights whenever the
amplifier is on. If the head unit
has a 12 volt automatic antenna
+
or amplifier remote activation
wire, connect it to the blue/white
wire of the GTS100x.
Some head units have no auto-
matic antenna or power amp
activation wire. Other decks have
automatic antenna wires that are
"on" only when the radio is used
(the 12 volt signal is off when a
+
tape is played). In such cases,
connect the remote turn-on wire
to an unused accessory terminal
in the fuse block, or any other 12
+
volt source that is turned on and
off with the vehicle's ignition
switch. The remote on/off system
draws negligible current, so a rel-
atively small (18 or 20 gauge)
extension wire may be used. Be
sure to securely crimp or solder
and insulate the wire-to-wire
connections.
