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
II
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
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.

Adjusting
the
type and range
of
the
frequency crossovers
With the
GTA
2 Special, the type
of
frequency crossover
(i.e.
"Low
Pass"
or
11
Hi-Pass
11
)
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
80Hz
to
25,000
Hz.
Low-pass frequency
control
This control
is
active
if
the switch
is
in the position
II
Low-Pass'~
and allows for setting the desired entry frequency.
Example:
At a setting
of
150Hz,
the amplifier
has
a frequency range
of
1
0
Hz
to
150
Hz.
Bass
boost
The
bass
boost control
is
used
to
adjust the
bass
response
of
the amplifier.
The adjustment range
is
from
0
dB
to+
12
dB.
