WHY YOU SHOULD
PAY
ATTENTION TO THIS OWNER'S MANUAL
The performance of your vehicle's audio system depends as much on quality installation and setup as it does on
quality gear. Of course, these new
JBL
® GTO amplifiers are bulletproof perfo
rm
ers that are built using the highest
quality components, and will outperform any competing prod
uct
on
the
test bench.
To
make sure you extract all
the performance possible from your new amp, whether you install it yourself or have a professional install it for you,
we've incorporated some new features that make se
tup
simple and precise and ensure you get
al
l the power and
performance you've paid for.
WHAT MAKES THESE AMPLIFIERS DIFFERENT
All amplifiers include some signal processing functions, level setting controls and other switches and
co
nnectors that
make it possible to hook the amp up
to
just about any existing system. However, with many amplifiers, considerable
technical expertise
is
required
to
make the best use
of
those connectors, switches and controls
to
get powerful noise-
free sound.
JBL
GTO amplifiers include Simple Setup designed
to
make it easy for you
to
get
all
the noise-free power
yo
ur
amp is capable
of
delivering.
WHAT MAKES INPUT SETUP EASY
GTO Amplifiers include adapters for connecting almost any analog signal and feature built-in Gain Indicator LEOs and
a setup CD that makes precision adjustment simple, no matter your level
of
experience. The setup
of
GTO amplifiers is
a little different than amplifiers you may have installed
in
the past, so please read this owner's manual before you
begin. If you're an experienced installer, skipping ahead is OK,
but
please
don't
skip Setup Procedure, on
page 8.
