BASS BOOST
Mit Hilfe des Bass Boost-Reglers kann die Basswiedergabe des Blau-
punkt-Verstärkers eingestellt werden. Der Einstellbereich reicht von 0
dB bis 0-12 dB.
SUB SONIC
Das Sub Sonic-Filter dient dem Verstärkerbetrieb bei angeschlosse-
nem Subwoofer. Es kann geregelt werden um den Subwoofer vor me-
chanischer Überlastung durch tiefe nicht mehr in den Hörbereich fal-
lende Frequenzen zu schützen.
Integrierte Sicherungen (FUSE)
Die im Amplifier integrierten Sicherungen (Fuse) schützen die End-
stufe und das gesamte elektrische System im Fehlerfall. Bei dem Ein-
satz einer Ersatzsicherung bitte niemals Sicherungen überbrücken oder
gegen Typen mit höherem Strom auswechseln.
Betriebsanzeige (POWER / PROTECTION)
Grünes Licht: Endstufe an, regulärer Betriebszustand.
Rotes Licht: Endstufe ist elektronisch abgeschaltet da Fehlerfall vor-
liegt.

Introduction (GB)
Congratulations on purchasing this high-quality car audio amplifier.
We, as innovators in car hi-fi systems, have built a new range of VPA
amplifiers (Class A/B) to provide you with entry to the discerning world
of audiophile components.
Exceptionally high power reserves and outstanding sound mean the
new Blaupunkt Velocity Series amplifiers impart a live feel to the mu-
sic in your car. A signal-to-noise ratio of over 100 dB, an extremely low
distortion factor, very high damping factor, high-quality materials, se-
lected components, first-class finish and cutting-edge technology lea-
ve nothing to be desired.
The large heat sink made from powder-coated aluminium is a hollow-
section design equipped with side ventilation openings to ensure opti-
mum heat dissipation and cooling even in the smallest and most unu-
sual installation locations.
The wire remote control that is included allows you to adjust the bass
level conveniently from your seat.
To ensure the best possible sound quality we recommend you have
your new Blaupunkt Velocity Series amplifier installed by an autho-
rised Blaupunkt dealer.
Please allow us to make a few comments on the issue of health:
When listening to music in your vehicle, remember that continuous
sound pressure levels of over 100 dB can lead to permanent hearing
damage and even total hearing loss. Modern high-powered systems
and high-quality loudspeaker configurations are capable of producing
sound pressure levels exceeding 130 dB.
We provide a manufacturer guarantee for our products bought within
the European Union. You can view the guarantee conditions at

Safety notices
Installation and connection instructions
The battery's negative terminal must be disconnected for the entire
time it takes to install and connect the device.
You must observe the vehicle manufacturer's safety notices (airbags,
alarm systems, trip computers, immobilizers) regarding this.

As regards safety in the event of an accident, the Blaupunkt power
amplifier must be professionally secured in position. The surface to
which it is attached must be suitable for the screws that are included
and must provide a secure hold.
When drilling holes, you must make sure that none of the vehicle com-
ponents (e.g. battery, cables, fuse box) can be damaged in the process.
The amplifier must be secured in a suitable installation location, e.g.
in the car boot (see Fig. 1).
When choosing an installation location, you should select one which
is dry and which provides sufficient air circulation to cool the amplifier.
Use cable grommets to protect cables against sharp-edged holes.
Use loudspeakers with an impedance of 2-4
imum load rating (music power rating).
Use loudspeaker connecting cables up to 12 mm
loudspeakers to earth – only use the correct terminals as indicated.
The cross section of the positive and negative cables must be at
2
least 16 mm
.
The positive cable between the battery and the amplifier must be
protected directly at the battery using a fuse holder (100-125 am-
peres).
Velocity High End Reference Amplifier VPA 4120
The amplifier is suitable for connection to car audio systems that are
equipped with RCA connections.
If you want to connect it to car audio systems that are equipped with
an ISO connection, please use the Blaupunkt ISO-RCA adapter.
