5. Fuse in the PASSIO SUB 15
To increase the operating safety of the PASSIO SUB 15, the subwoofers are equipped with
fuses at the signal input. These fuses reduce the risk of consequential damage resulting from
a short circuit (i.e. charred cables / connectors / fire damage).
When the fuse is burned out, then the chassis is most likely already ruined, as the fuse just
prevents consequential damage resulting from a short circuit of the chassis. A replacement of
the chassis is, therefore, unavoidable.
5.1 Replacing the Fuses
The fuse holder is behind the terminal.
Warning
Replace the fuse with the following original fuse only:
Bussmann S 506-8A, T 250V
Required tools:
• 2.5 mm Allen key for loosening the terminals
Instructions:
1. Loosen the four screws on the terminal.
2. Carefully pull the cables out of the speaker enclosure.
3. Open the fuse holder.
4. Replace the blown fuse.
5. Push the cables carefully back into the enclosure.
6. Pay attention to the correct alignment of the terminal.
Screw the terminal back on.
5.2 Replacing the Chassis
Required tools:
• 3 mm Allen key for loosening the front grille
• 3 mm Allen key for loosening the chassis
Instructions:
1. Remove the front grille.
2. Remove the speaker chassis.
3. Pay attention to the correct polarity of the chassis.
Connect the new chassis.
4. Check the polarity of all mounted chassis.
5. By tightening the screws diagonally in two steps, a deformation of the chassis and thus a
possible deentring of the voice coil can be avoided. First loosely fasten the screws for the
chassis diagonal from one another, then tighten them.
6. Mount the front grille.
