Spannungsquelle verbinden.
Auf
dieseWeise kann derVerstarker uberden
Ein-1
Ausschal-
ter des Radiogerats ein- und ausgeschaltet werden.
Level Regier
Mit
Hilfedes Level Reglers kann die Eingangsempfindlichkeit
der Endstufe
an
die Ausgangsspannung lhres Autoradio-
Vorverstarkerausganges angepasst werden.
Der Einstellbereich reicht von
0,1
V bis 8
V.
Bei
Anschluss eines Autoradios anderer Hersteller ist die
Eingangsempfindlichkeit entsprechend den Herstelleran-
gaben anzupassen.
Hierzu noch einige wichtige ErUiuterungen:
Durch Drehen des Reglers im Uhrzeigersinn
erhoht
sich
die
Eingangsempfindlichkeit
des Verstarkers
und
damit
auch die Lautstarke.
Es
handelt sich jedoch nicht urn eine
Lautstarkeregelung; in
der
Endposition
lasst sich keine
hohereVerstarkerleistung erzielen, auch wenn sich dies zu-
nachst
so
anhort.
Das
System steigert lediglich schnellerdie
Lautstarke, wenn die Lautstarkeregelung des Radiogerates
aufgedreht wird.
Lautsprecheranschlusse
(Falls der Verstarker in Brucke geschaltet werden soli,
an
dieser Stelle direkt
mit
dem Abschnitt ,Oberbruckte Laut-
sprecheranschlusse" fortfahren).
Wie beijeder
Audiokomponente
ist die korrekte Polung von
Verstarker und Lautsprechern von essentieller Bedeutung
fUr
eine
gute
Basswiedergabe. Deshalb ist bei den Anschlussen
darauf
zu
achten, dass der positive
(+)
Anschluss des Ver-
starkers
mit
dem positiven Anschluss(+) des Lautsprechers
verbunden wird; entsprechendes
gilt
fur die negativen
(-)
Anschlusse.
Au~erdem
muss der Iinke Verstarkerkanal
mit
dem linken Lautsprecher und derrechteVerstarkerkanal
mit
dem rechten Lautsprecher verbunden werden.
Oberbruckte Lautsprecheranschlusse
Der GTA-Verstarker kann
fur
eine Monokonfiguration auch
in Brucke geschaltet werden.
Auf
diese Weise kann
der
Verstarker
fur
einen
oder
mehrere Subwoofer bzw. einen
4
Mitteltoner
verwendet werden.
In
dieser Konfiguration ad-
diert
derVerstarker den rechten und linken
Kana
I
zu
einem
Einkanalausgang (Monoausgang).
Hinweis:
Der Verstarker kann die rechte und Iinke Signalinformation
nur
dann addieren, wenn sowohl der rechte
als
auch der
Iinke RCA-Anschluss vorgenommen wurde.
Achtung:
In Bruckenschaltung muss
die
Verstarkerlast 4 Ohm
oderhoher betragen. Eine niedrigere Last
fuhrt
zu einer
Oberhitzung oderAbschaltung des Verstarkers und kann
dauerhafte Schaden verursachen.
Art
und Bereich der Frequenzubergange
einstellen
Beim
GTA
470
SF
kann
die
Art
des Frequenzubergangs
(d.
h.
,Low-Pass" oder,Hi-Pass") und die gewunschte Ein-
stiegsfrequenz eingestellt werden. Wenn beispielsweise
ein Subwoofer-Paar angeschlossen werden soli, sind
die
abgebildeten,Low-Pass"-Einstellungen erforderlich
(Fig.
3).
Die Einstiegsfrequenz ist abhangig vom Frequenzbereich
der Lautsprecher (siehe empfohlener Frequenzbereich der
Lautsprecher).
,High-Pass"
Bei
der Einstellung von 80
Hz
hat der Verstarker einen Fre-
quenzbereich von
80Hz
bis 30.000
Hz.
,Low-
Pass"- Frequenzregelung
Dieser Regier ist aktiv, wenn sich derSchalter in derPosition
,Low-Pass" befindet, und
ermoglicht
die Einstellung
der
gewunschten Einstiegsfrequenz.
Beispiel:
Bei
einer Einstellung von 150
Hz
hat der Verstarker einen
Frequenzbereich von
10
Hz
bis 150
Hz.

you would
to
install
it
yourself,
please read these installation instructionsvery carefully and
allow yourselfsufficient
time
for the installation.
In conclusion, allow
us
afew words aboutthe topic
of
health
protection:
During theplayback
of
music in yourvehicle, 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.

+12V 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 poweramplifier
to
the
output
voltage
of
yourcar sound
system preamplifier
output.
The adjustment range
is
from
0.1
V
to
8
V.
If
a car sound system
of
a
third
party manufacturer
is
con-
nected,the
input
sensitivitymustbe adjusted corresponding
to
the manufacturer data.
A few
important
explanations in this context:
By
turning
the control clockwise, the
input
sensitivity
of
the
amplifierand, 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
(Ifthe amplifier
is
to
bejumpered,continue with the section
"Bridged loudspeaker connections" at this point).
As
with
every audio component, the correct polarisation
of
amplifierand loudspeakers
is
of
essentially importancefora
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
amplifiercan also be bridged fora
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.Alowerload 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
470
SF,
the type
of
frequency crossover
(i.e.
"Low
Pass"
or "Hi-Pass") and the desired
entry
frequency
can
be adjusted.
For
example,
if
apair
of
subwoofers
is
to
be
connected, the low-pass settings shown are required
(Fig.
3).
The entryfrequency
is
dependentupon the frequency range
of
the loudspeakers
(see
recommended frequency range
of
the loudspeakers).
High-Pass
At asetting
of
80
Hz,
the amplifier
has
afrequency range
of
80
Hz
to
30,000
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.

Kao
i kod svih audio uredaja, ispravna polarizacija pojacala
i zvucnika nuzna
je
za
dobru
reakciju niskih tonova. Zbog
toga
osigurajte
da

GTA470 SF
When selecting the installation location, select a dry loca-
tion that offers sufficient air circulation for cooling the
amplifier.
The GTA 470 SF 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 amplifierpowercable must be fitted with afuse no more
than
30 em from the battery to protectthevehicle batteryin
case of ashort circuit between power amplifierand battery.
The fuse
of the amplifier protects onlythe 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 470 SF
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 (7 607 893 093 or
7607
855 094).

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.
Integrated fuses (Fuse)
The fuses integrated in theamplifier (Fuse) protectthepower
amplifierand
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.
Connection examples

cinch output ....................................................................... Fig. 3
Loudspeaker connections ............................................. Fig. 4/5/6
I -/o- +12V 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 poweramplifier to the output voltage of yourcar sound
system preamplifier output.
The adjustment range
is from 0.1 V to 8 V.
If a car sound system of a third party manufacturer is con-
nected,the
input sensitivitymust be adjusted corresponding
to the manufacturer data.
A few
important explanations in this context:
By turning the control clockwise, the input sensitivity of the
amplifierand, therefore, also thevolume 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
(Ifthe amplifier is to be jumpered,continue with the section
II Bridged loudspeaker connections II at this point).
As with every audio component, the correct polarisation of
amplifierand loudspeakers is of essentially importancefor 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 amplifiercan 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.Alowerload leads
to an overheating orswitch-off
of the amplifier and can cause permanent damages.
Adjusting the type and range of the
frequency crossovers
With the GTA 470 SF, the type of frequency crossover (i.e.
"Low Pass" or "Hi-Pass") and the desired entry frequency
can be adjusted. For example,
if apair of subwoofers is to be
connected, the low-pass settings shown
are required (Fig. 3).
The entryfrequency is dependentupon thefrequency range
of the loudspeakers (see recommended frequency range of
the loudspeakers).
High-Pass
At a setting of 80 Hz, the amplifier has afrequency range of
80 Hz to 30,000 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 10 Hz to 150 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.
Power-on indicator (POWER I PROTECTION)
Green LED:
Output stage on, regular operating status.
Red
LED:
