Heat Protection Mode
If the display indicates an “H”, the amp is too hot. This is
rarely
seen, but a few extreme situations can invoke this mode:
a) If the amplifier is used in an environment that is too hot, or if
proper ventilation is not ensured.
b) The Load Impedance switch on the amplifier’s back plate
must match the load of the connected cabinet configuration.
If the Load Impedance switch is set to 4 Ohm and the
amplifier is run at high levels over a long period of time with
a 2 Ohm speaker configuration, the amplifier may enter Heat
Protection mode.
In both situations, 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.
Notice that due to Blacksmiths protection features the
amplifier will NOT be damaged if a wrong Load
Impedance setting is selected.
Protection mode
BLACKSMITH 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
If the BLACKSMITH’s display indicates “P”, the amp is in
Protection mode.
Protection mode is invoked if for some reason a short-circuit
situation occurs. In Protection mode, the speaker outputs are
shut off so that the speakers cannot be damaged by a shortcut.
The balanced output, digital recording out and the effects loop,
however, are still passing audio in Protection mode.
To remedy the problem, try turning off your BLACKSMITH for
a minute and then turn it on again. If the display still indicates
“P”, you will have to send your BLACKSMITH to a qualified
service-center for inspection.
