REAR PANEL FEATURES AND FUNCTIONS
Located on the BASSBASE 250’s rear panel, you will find the AC power supply
socket for the factory supplied Euro-mains lead. Integrated into the AC power supply
socket is the FUSE bracket.
In order to change a fuse, depress the fittings on both sides of the bracket and pull
the fuse out. The appropriate fuse amperage for each model can be determined by
reading the value annotated below the fuse bracket.
VOLTAGE SELECTOR:
All European models can be adjusted to operate at 220V or 240V. Rotate the insert
in the fuse bracket to the desired position. The correct voltage is determined by the
number visible in the upper region of the fuse bracket. Ensure this number
corresponds to the voltage specifications of your country. Also ensure that the fuse
bracket is completely secure after changing a fuse or adjusting the voltage.
SPEAKER
This speaker jack is suitable for connecting an external speaker. The combo
model’s speakers are factory connected to this jack. The Bassbase’s speaker
combination was designed to take advantage of the amp’s maximum output; thus the
overall impedance of 4 ohms. External speakers for the combo version should be
used as an alternative, not an addition
