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 chann·el
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
mid-range drivers.
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
RCA
connection were
carried out.
Caution:
In
a bridge circuit, the
amplifier load
must
be
4
ohm
or
higher.
A
lower
load
leads
to
an
overheating
or
switch-off
of the
amplifier
and
can
cause
permanent damages.
6
Adjusting
the
type and range
of
the
frequency crossovers
With the
GTA
4
Special,
the type
of
frequency crossover (i.e.
"Low
Pass"
or
"Hi-Pass")
and the desired
entry
frequency can
be adjusted.
For
example,
if
a pair
of
subwoofers
is
to
be
connected, the
low-pass
settings shown are required
(Fig.
3).
The entry frequency
is
dependent upon the frequency range
of
the loudspeakers
(see
recommended frequency range
of
the
loudspeakers).
High-Pass
At a setting
of
80Hz,
the amplifier
has
a frequency range
of
80
Hz
to
25,000
Hz.
Low-pass frequency
control
This
control
is
active
if
the switch
is
in
the position
"Low-Pass':
and allows
for setting
the
desired entry frequency.
Example:
At a setting
of
150
Hz,
the
amplifier
has
a frequency range
of
1
0
Hz
to
1
50
Hz.
Bass
boost
The
bass
boost
control
is
used
to
adjust
the
bass
response
of
the
amplifier.
The setting options
are:
0
dB
I
+6
dB
I+
12
dB.
