Recommendation:
The performance of an amplifi er can only be as good
as its installation. A correct installation increases the
overall performance of your car sound system. The GTA
amplifi er should be installed by a trained person. If you
would to install it yourself, please read these installation
instructions very carefully and allow yourself suffi cient
time for the installation.
In conclusion, allow us a few words about the topic of
health protection:
During the playback of music in your vehicle, 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 confi gurations allows for
reaching sound-pressure levels above 130 dB.
Safety notes
Please observe the following safety notes
during the installation and connection.
- Disconnect the negative pole of the battery!
Observe the safety notes of the vehicle manufacturer.
- When you drill holes, ensure that you do not damage any vehicle components.
- The cross section of the plus and minus cable may
not be less than 6 mm
- Use cable glands for holes with sharp edges.
- An incorrect installation can result in malfunctions
of the electronic vehicle systems or your car sound
system.
Installation and connection instructions
With respect to accident safety, the GTA 480 must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers suffi cient air circulation for cooling
the amplifi er.
2
(5 A.W.G.).
The GTA 480 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
accompanying screws and provide a fi rm support.
The amplifi er power cable must be fi tted with a fuse no
more than 30 cm (1,18") from the battery to protect the
vehicle battery in case of a short circuit between power
amplifi er and battery. The fuse of the amplifi er protects
only the amplifi er, not the vehicle battery.
Use loudspeakers with 2-4 Ω impedance (see table or
installation drawing). Observe the maximum power
handling capacity (music output). Do not connect loudspeakers to earth, use only the referenced terminals.
Amplifi er GTA 480
The amplifi er is suitable for connecting a car sound
system with cinch connections.
For the connection to car sound systems with
ISO connection, use Blaupunkt ISO cinch adapters
(7 607 893 093 or 7 607 855 094).

Plus / minus connection
- We recommend a minimum cross section of 6 mm
(5 A.W.G.).
- 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 amplifi er (Fuse) protect the
power amplifi er 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.

+12V
Remote connection of the amplifi er with switchable +12 V
voltage source.
This allows the amplifi er to be switched on and off using
the on/off-switch of the radio device.
Direct Aux Input Connection
Connection options if the car radio has no AUX
input or if the AUX input is already connected
You can directly connect various AF sources (such
as an MP3 player or mobile navigation system) via
a 3.5 mm (0,35") jack plug optionally to the Direct
Aux Input. All signal sources will then be heard simultaneously and their volume must be adjusted
on the respective source device.
Note:
All AF sources must be set to Off during installation and connection!
Installing the jack-plug cable
Please use our 5 m (16.4 ft.) jack-plug cable (Or-
der No. 7 607 001 525) to make the connection.
A special feature is that it has its own On/Off
switch.
Switch position is OFF (•):
During installation and de-installation and when
no AF source is connected.
Switch position is ON (I / II):
Only after an AF source has been connected.
Caution:
When making the connection, always set the vol-
ume control to minimum and switch off the amplifi er.
Level control
The Level control is used to adjust the input sensitivity
of the power amplifi er to the output voltage of your car
sound system preamplifi er output.
The adjustment range is from 0.3 V to 8 V.
If a car sound system of a third party manufacturer is
connected, 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 amplifi er and, therefore, also the volume increases.
However, this is not a volume control; no further amplifi er 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.
High-level inputs
The amplifi er is equipped with high-level inputs to permit
connection to radios without preamp outputs (Fig. 7).
This enables direct connection to be made to the radio’s
loudspeaker output.
Loudspeaker connections
(If the amplifi er is to be jumpered, continue with the section "Bridged loudspeaker connections" at this point).
As with every audio component, the correct polarisation of amplifi er and loudspeakers is of essentially
importance for a good bass response. For this reason,
ensure that the positive (+) connection of the amplifi er
3
GTA 480
is connected with the positive connection (+) of the
loudspeaker; the same applies to the negative (-) connections. In addition, the left amplifi er channel must
be connected with the left loudspeaker and the right
amplifi er channel with the right loudspeaker.
Bridged loudspeaker connections
The GTA amplifi er can also be bridged for a mono
confi guration. This allows the amplifi er to be used for
one or several subwoofers or mid-range drivers. In this
confi guration, the amplifi er combines the right and left
channel to a single-channel output (mono output).
Note:
The amplifi er 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 amplifi er load must be 4 ohm
or higher. A lower load leads to an overheating or
switch-off of the amplifi er and can cause permanent
damages.
Adjusting the type and range of the frequency
crossovers
With the GTA 480, 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 250 Hz, the amplifi er has a frequency
range of 250 Hz to 35.000 Hz.

Output stage is electronically switched off due to an

建議:
放大器的性能直接受到其安裝的影響。正確的安裝可提高您
的汽車音響系統的整體性能。GTA 放大器應該由接受過培訓
的人員進行安裝。如果希望自己安裝，請仔細閱讀這些安裝
說明，並要用充足的時間進行安裝。
最後，我們要談談健康保護的話題：
在裝置中播放音樂期間，請注意聲壓級持續高於 100 分貝可
能對人耳造成永久損失甚至失聰。使用今天的高性能系統和
揚聲器配置，可將聲壓級達到 130 分貝以上。
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 amplifi er 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 amplifi er.
The adjustment range is from 0 dB to +12 dB.
