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 BH250 / BG250-208 cooling
grid! Insufficient ventilation may cause the amplifier’s
temperature to increase to critical values.
The BH250 / BG250-208 is equipped with an intelligent
protection system, ensuring that the amp does not suf-
fer or malfunction if operated wrongly or in extreme en-
vironments. 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.
■ if proper ventilation is not ensured.
■ if the combined impedance of the internal speaker
and an attached speaker is below 4 Ohms.
In Protection mode, the speaker outputs are shut off to
prevent speaker damage. However, the balanced out-
put still passes audio.
