Blaupunkt GTA 4 Special User Manual

GTA
4
Special Edition
2011
When selecting
the
installation location, select a
dry
loca-
tion
that
offers
sufficient
air circulation
for
cooling
the
amplifier.
The
GTA
4 Special must
not
be installed
on rear shelves, rear
seats
or
other locations
that
are open
to
the
front.
The installation location 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.
Use
loudspeakers
with
2-
4
n
impedance
(see
table
or
in-
stallation drawing). Observe the maximum power handling
capacity (music output). Do
not
connect loudspeakers
to
earth,
use
only
the
referenced terminals.
Amplifier
GTA
4
Special
The amplifier
is
suitable for connecting a car sound system
with
cinch connections.
For
the
connection
to
car sound systems
with
ISO
connec-
tion, use Blaupunkt
ISO
cinch adapters
(7

We

•
- 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.
Integrated
fuses
{Fuse)
The fuses integrated in the amplifier
(Fuse)
protect the power
amplifier and
the
entire electrical system in
case
of
an
error.
If
a replacement fuse
is
used, never bridge fuses
or
replace
them
with
a
type
with
higher current.

I
Remote connection
of
the
amplifier
with
switchable
+
12 V
voltage source.
This allows
the
amplifier
to
be switched on and
off
using
the
on/off-switch
of
the
radio device.
Level
control
The
Level
control
is
used
to
adjust
the
input
sensitivity
of
the
power
amplifier
to
the
output
voltage
of
your car sound
system preamplifier
output.
The adjustment range
is
from
0.3
V
to
8
V.
If
a car sound system
of
a third party manufacturer
is
con-
nected,
the
input
sensitivity must be adjusted corresponding
to
the
manufacturer data.
A few
important
explanations in this context:
By
turning
the
control
clockwise,
the
input
sensitivity
of
the
amplifier and, therefore, also the volume increases. However,
this
is
not
a
volume
control;
no
further
amplifier
output
can be achieved in the end position, even
if
it
may sound
like
that
at
the
beginning. The system merely increases
the
volume faster
if
the
volume control
of
the car sound system
is
turned up.
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.
