Blaupunkt GTA 2 Special User Manual

GTA
2
Special
Edition
2011
When selecting the
installation
location, select a
dry
loca-
tion
that
offers sufficient air circulation for cooling
the
amplifier.
The
GTA
2 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
2
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

•
- 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.
