Recommendation:
Introduction
A power amplifier’s performance is only as
good as its installation. Proper installation
will maximise the overall performance of your
audio system. We recommend that you have
our product installed professionally. Should
you decide to install the amplifier yourself,
however, please read through these instructions carefully, and take your time over the
installation.
Finally, a word about your health: please bear
in mind when playing music in your car that
sustained sound levels above 100 dB can
damage your hearing and may even result
in total hearing loss. Modern high-performance systems and high-quality loudspeaker
configurations are quite capable of generating noise levels above 130 dB
Congratulations on your purchase of a highquality BGA power amplifier. By selecting the
BGA 250 you have chosen a product which
delivers superlative reproduction quality.
Whether you are upgrading an existing system or using the BGA power amplifier in a
new system, you are certain to notice immediate performance benefits!
The Blaupunkt editors are constantly working on making the operating instructions
clearer and easier to understand. However,
if you still have any questions on how to operate the equipment, please contact your
dealer or the telephone hotline for your country. You will find the hotline telephone numbers printed at the back of this booklet.
We provide a manufacturer guarantee for our
products bought within the European Union.
You can view the guarantee conditions at

Safety precautions
Instructions for installation and
connection
Fit a fuse in the amplifier power line no more
than 30 cm from the vehicle battery, in order
to protect the battery in the event of a shortcircuit between it and the power amplifier.
The amplifier’s own fuse protects the amplifier itself, but not the car battery. Disconnect the negative terminal of the battery
before carrying out installation and connection work.
Observe the vehicle manufacturer’s safety
instructions (regarding airbags, alarm systems, trip computers, vehicle immobilisers).
The final stage must be installed professionally for reasons of safety. The mounting surface must be suitable for the screws provided, and must provide firm support.
When drilling holes, take care to avoid damage to vehicle components (battery, cables,
fuse boxes).
7
BGA 250
Fit the amplifier in a suitable location, e.g.
beneath the seats or in the trunk (Fig. 1).
The mounting location must also be dry, and
provide sufficient ventilation for cooling of the
amplifier. Use cable grommets when passing cables through holes with sharp edges.
Use loudspeakers with an impedance of
2 to 4 Ω (see table or installation drawing).
Observe the max. power handling specifications (music output). Do not connect the
loudspeakers to ground; only use the terminals provided. The cross-section of the positive and negative cable must be at least
6 mm2.
8
BGA 250 amplifier
The amplifier is suitable for connection to car
radios with Cinch connector. Use the Blaupunkt ISO Cinch adapter to connect the
amplifier to car radios with ISO connector (7 607 893 093/ 7 607 855 094).

Positive/negative connection
We recommend a cable cross-section of not
less than 6 mm2. Run a standard commercial positive cable to the battery and connect to the fuse holder. Use cable grommets
when passing cables through holes with
sharp edges. Bolt a standard commercial
negative cable to a ground point free of induced noise (car body bolt, body panel) not to the negative battery pole. Clean the
contact surface of the ground point down to
bare metal and coat with antiseize graphite
petroleum.
Integral fuses
The integral fuses within the amplifier protect the final stage and the entire electrical
system in the event of a fault. Never bridge
fuses or replace fuses with a higher current
rating.
Example connections
Power supply connection fig. 2.
Connection of car radio with cinch output
fig. 3.
Loudspeaker connections fig. 4.
+12V
Connect remote amplifier connection to switchable +12 V power
source.
This enables the amplifier to be switched on
and off with the radio’s On/Off switch.
Level control
The Level control enables the input sensitivity of the final stage to be matched to the
output voltage of your car radio preamp output.
The range of adjustment extends from 0.1 V
to 8 V.
Adjust the input sensitivity in accordance with
the manufacturer’s specifications when connecting the amplifier to other radios.
Important:
Turning the Level control clockwise increases the input sensitivity of the amplifier, and
thereby also the volume. The Level control
is however not a volume control; an increase
in volume is not achieved in the maximum
position, even if this subjectively appears to
be the case. The system merely increases
the volume more quickly when the volume
is turned up on the radio.
Loudspeaker connections
(If the amplifier is to be connected in a
bridged mode, proceed with the section
“Bridged loudspeaker connections”.)
As with any audio component, connection
of the amplifier and speakers with the correct polarity is essential for good bass reproduction. Ensure therefore when connecting that the positive (+) amplifier terminal is
connected to the positive (+) loudspeaker
terminal. The same applies to the negative
(-) terminals. The left-hand amplifier chan-
9
BGA 250
nel must also be connected to the left-hand
loudspeaker and the right-hand amplifier
channel to the right-hand loudspeaker.
Bridged loudspeaker connections
The BGA can also be bridged in a mono configuration. This enables you to use the amplifier for one or more subwoofer(s) or a midrange speaker. In this configuration the amplifier sums the right-hand and left-hand
channels, delivering a single channel (mono)
output.
“Low-pass” frequency control
Note:
The amplifier can sum the right- and left-hand
signal information only if both the right- and
left-hand RCA connections have been made.
Operating indicator
(POWER / PROTECTION)
CAUTION:
The amplifier must be presented with a
load of 4 Ohms or higher in bridged
mode. A lower load will cause the amplifier to overheat or switch off. This can
lead to permanent damage of the unit.
Adjustment of the type and range
of the cross-over frequencies
The type of crossover (i.e. “low-pass” or “hipass”) and the desired crossover frequency
can be selected on the BGA 250. If, for example, you wish to drive a pair of subwoofers, connect in accordance with the low-pass
diagram (fig. 3). The crossover frequency is
dependent upon the loud-speaker frequency range (consult the loudspeaker manufacturer’s data for the recommended frequency range).
“High- Pass” frequency control
This control is active when the switch is in
the “Hi-pass” position, and permits selection
of the desired crossover frequency. Example: at a of 65 Hz, the loudspeaker has a
frequency range of 65 Hz to 30.000 Hz.
10
This control is active when the switch is set
to “Low-pass” and permits selection of the
desired crossover frequency. Example: at a
setting of 150 Hz, the loudspeaker has a frequency range of 10 Hz to 150 Hz.
Bass boost
You can adjust the bass output of the amplifier using the bass boost control. The settings range covers 0 dB to +18 dB.
Green lamp: Power amp on, regular operating condition
Red lamp: Power amp has been switched
off electronically, due to a fault or failure.
