Protection mode
BH550 / BH800 English Manual (2014-10-01) 18
This product is equipped with an advanced pro-
tection system for both the amplifier’s and your
own safety. These protection features will only
kick in if you operate this product under extreme
conditions.
Be sure not to cover the cooling grid of your bass
amp! Insufficient ventilation may cause the am-
plifier’s temperature to increase to critical values.
Your bass amp is equipped with an intelligent
protection system, ensuring that the amp does
not suffer or malfunction if operated wrongly
or in extreme environments. 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)
►
if the amplifier is used in an environment that
is too hot, or
►
if proper ventilation is not ensured.
In Protection mode, the speaker outputs are shut
off to prevent speaker damage. However, the
balanced output still passes audio.
How to proceed in
Protection mode
► If the amplifier does not automatically recover
from Protection mode and feels hot, try turn-
ing off the amplifier for a minute to let it cool.
Ensure sufficient ventilation.
► Ensure that your speaker(s) and speaker
cable(s) are not defect, as such a defect
could cause a short circuit.
►
Turn on the amplifier again.
If these steps do not solve the problem and the
Tuner LEDs continue flashing, you will have to
send the amplifier to a qualified service center
for inspection.
