Power switch & Power input
The switched-mode power supply of this device ac-
cepts voltages from 100V to 240V. The ground pin of
the power supply unit must always be connected in
order to avoid voltage differences between e.g. the PA
and your bass combo.
Protection mode
This product is equipped with an advanced protection
system for both the amplifier’s and your own safety.
These protection features should only kick in if you op-
erate this product under extreme conditions.
Be sure not to cover the cooling grid of your bass
combo! Insufficient ventilation may cause the ampli-
fier’s temperature to increase to critical values.
Your bass combo is equipped with an intelligent pro-
tection system, ensuring that the amp does not suffer
or malfunction if operated wrongly or in extreme envi-
ronments. When the amplifier switches to Protection
mode, the speaker output is muted, and the TUNER
LEDs start flashing in pairs of two.
Protection mode is invoked…
■ if a short circuit occurs (on speaker outputs).
