Ventilation
Be sure not to cover the BH500 cooling grid!
Insufficient ventilation may cause the amplifier’s temperature to
increase to critical values.
Protection Modes
The BH500 is equipped with an intelligent protection system,
ensuring that the amp does not suffer or malfunction if operated
wrongly or in extreme environments.
General Protection Mode
When the BH500 switches to Protection mode, the MUTE LED
is lit while the first two and last two Compression LEDs light up
in turn.
Protection mode is invoked when (for whatever reason) a short
circuit situation occurs.
A short circuit would typically occur in the situation where:
- you use a non-TC cabinet with a jack connection
- connect using a Speakon to jack cable
- plug/un-plug the jack going in to the cabinet while the amp is
turned on.
In Protection mode, the speaker outputs are shut off to prevent
speaker damage. However, the balanced output passes audio
even in Protection mode.
To remedy the problem, try turning off the BH500 for a minute
and then back on again. If the LED pattern described here
shows again, you will have to send the BH500 to a qualified
service center for inspection.
Heat Protection Mode
When the BH500 switches to Heat Protection mode, the
PEAK and MUTE LEDs are lit while the first two and last two
Compression LEDs light up in turn.
Heat Protection is invoked if the amplifier is used in an
environment that is too hot, or if proper ventilation is not
ensured.
Proceed as follows:
– Turn off the amplifier.
– Solve the issues.
– Allow the amplifier to cool off for a few minutes.
– Turn on the amplifier again.
