2 Safety Notes
The unit corresponds to the directive 89/336/EEC for
electromagnetic compatibility.
! When connecting the car HiFi booster to the car bat-
tery, be especially careful. In case of short circuits
there may be very dangerously high currents. There-
fore, prior to the connection it is absolutely neces-
sary to screw off the negative terminal of the car bat-
tery.
! The booster must be mounted to a mechanically
stable place in the car. It must be skilfully fixed so
that it does not get loose and turn into a dangerous
projectile.
! During operation the booster can become very hot.
Therefore, do not place any objects sensitive to heat
near the booster and do not touch it while in opera-
tion.
! For cleaning only use a dry, soft cloth, by no means
chemicals or water.
! If the booster is used for purposes other than orig-
inally intended, if it is not correctly operated or
connected or not repaired by authorized personnel,
no liability can be taken over for any possible
damage.
! If the unit is to be put out of operation definitively, it
must be disposed of in a local recycling plant.
3 Caution in Case of High Volumes
! Never adjust the volume very high. Extremely high
volumes may damage the hearing.
! The human ear gets accustomed to high volumes
which do not seem to be so high any more after
some time. Therefore, do not increase a high volume
which has once been adjusted after getting used to it.
! While driving in the car, signal sounds, e. g. by an
ambulance, must not be drowned by the volume of
the car HiFi system adjusted too high.
4 Applications
The booster HPB-250 has especially been designed
for car HiFi systems. Two full range speakers can be
operated with this booster. Due to the integrated cross-
over networks, an existing system can also be com-
pleted by two satellite speakers or two bass speakers
resp. a subwoofer.
5 Mounting
When choosing the place of mounting, always observe
the following items in any case:
! The 12 V power supply cable from the battery to the
car HiFi booster should be as short as possible. It is
more advantageous to use longer speaker cables
and a shorter power supply cable instead.
! The ground cable from the booster to the chassis of
the car should also be as short as possible.
! For carrying off the heat being generated in the
booster, a sufficient ventilation has to be ensured.
!
Because of the forces occurring during braking, the
booster must be screwed to a mechanically stable
place.
! The fuse and the controls must be accessible.
For mounting use the four drill holes at the heat sink.
Firmly mount the car HiFi booster to a suitable place
with four screws.
6 Connections
!
The connection of the car HiFi booster to the electric
system of the car must only be carried out by author-
ized personnel.
! To prevent damage in case of a possible short circuit
during installation, prior to connection it is absolutely necessary to screw off the negative terminal of the
car battery.
! Lay the necessary cables so that their insulation
cannot be damaged.
The complete connection is shown in fig. 3.

6.1 Power supply

6.1.1 Terminal RMT (8)
The car HiFi booster is switched on and off by a +12 V
control voltage at the terminal RMT. Connect the termi-
nal RMT to the 12 V output of the car radio (connection
for a motor antenna, if necessary to be connected in
parallel with the motor antenna). If no 12 V output is provided at the car radio, the
terminal RMT must get +12 V via the ignition lock or a
separate switch.
6.1.2 Terminal +12 V (9)
Connect the terminal +12 V via a cable with a cross
section of min. 10 mm 2
