Recommendation
The performance
of
an
amplifier
can
only
be
as
good
as
its
installation.
A correct installation
increases the
overall
performance
of
your car sound system. The
GTA
amplifier
should
be installed
by a trained
person.lfyou would
to
install
it
yourself, please read these
installation instructions very
carefully
and allow yourself
sufficient time for the
installation.
In
conclusion, allow
us
a few words about the topic
of
health
protection:
During the playback
of
music in your
vehicle, please consider
that
continuous sound-pressure
levels
above 100
dB
can
lead
to
permanent damages
to
the human ear and even
to
loss
of
hearing. Using today's high-performance systems
and loudspeaker
configurations
allows
for reaching sound-
pressure
levels
above
130
dB.
Safety notes
Please
observe the
following
safety notes during the
instal-
lation
and connection.
- Disconnect
the
negative pole
of
the battery! Observe the
safety notes
of
the
vehicle
manufacturer.
When you
drill holes,
ensure that you do
not
damage any
vehicle
components.
The
cross
section
of
the
plus
and minus
cable
may
not
be
less
than 6
mm
2
•
Use
cable glands
for
holes
with
sharp edges.
- An incorrect
installation can
result
in malfunctions
of
the
electronic vehicle
systems or your car sound system.
Installation and connection instructions
With respect
to
accident safety, the
GTA
270
DSP
must be
secured in a professional way.
When
selecting the installation location, select
a dry
location
that
offers sufficient air circulation for
cooling
the amplifier.
The
GTA
270
DSP
must
not
be
installed
on rear
shelves, rear
seats or other locations that are open
to
the front.
The
installation
surface must be
suitable
to
accept the
ac-
companying screws and provide a firm support.
The
amplifier power
cable
must be fitted with a fuse no more
than
30
em
from the battery
to
protect the
vehicle
battery in
case
of
a short circuit between power
amplifier and battery.
The fuse
of
the
amplifier
protects
only
the amplifier,
not
the
vehicle
battery.
Only
loudspeakers
with
2 - 4
n impedance may be used
(see
table or
installation drawings). Observe the maximum
power handling capacity (music output). Do
not
connect
loudspeakers
to
earth,
use
only
the referenced terminals.
6
Audio inputs
The preamplifier outputs are connected
to
the cinch
(RCA)
sockets via a
shielded audio
line
(see
Fig.
3).
Plus
I
minus connection
-
We
recommend a
minimum
cross
section
of
6 mm
2
•
- Route commercially available plus cables
to
the battery
and connect via fuse
holder.
-
Use
cable glands
for holes
with
sharp edges.
-
Securely
fasten commercially available
minus
cables
to
a
noise-free earth
point
(chassis screw, chassis metal) (not
to
the minus
pole
of
the battery).
- Scrap the contact surfaces
of
the earth
point
until
they
are
bright
and grease
with
graphite grease.
Integrate fuse
(20
A)
The
fuse integrated
in
the amplifier
protects the
output
stage
and the entire
electrical
system in
case
of
a malfunction.
If
a
replacement fuse
is
used, never bridge fuses or
replace
them
with
a type
with
higher current.

Remote connection

This
allows
the
amplifier
to

using the
on/off-switch
of
the car sound system.
Loudspeaker connections
(If
the
amplifier
is
to
be jumpered, continue
with
the section
"Bridged loudspeaker connections" at this point).
As
with
every audio component, the correct polarisation
of
amplifier
and loudspeakers
is
of
essentially
importance for a
good
bass
response.
For
this reason, ensure
that
the positive
connection(+)
of
the
amplifier
is
connected
with
the posi-
tive connection(+)
of
the loudspeaker; the same applies
to
the negative connections
(-).
In
addition, the
left amplifier
channel
must be connected
with
the
left
loudspeaker and
the right amplifier
channel
with
the right
loudspeaker.
Bridged loudspeaker connections
The
GTA
amplifier
can
also
be bridged for a
mono
configura-
tion. This allows
the amplifier
to
be used for one or
several
subwoofers or a mid-range driver.
In
this configuration, the
amplifier
combines the right and
left channel
to
a
single-
channel
output
(mono output).
Note:
The
amplifier
can
add the right and left signal
information
only
if
the right
as
well
as
the left
cinch
(RCA)
connection
were carried out.
Caution:
In
a bridge circuit, the amplifier load must be 4
n
or
higher. A lower load leads to an overheating or switch-
off
of
the amplifier and
can
cause permanent damages.
