Cause: An excessive current flowed through the power
amplifier.
Turning on the power without correcting the abnormality
will cause the protection function to work immediately and
the power supply will instantly be shut off.
Note)
• Applying the power to a unit without correcting the
abnormality can be dangerous and cause additional
circuit damage.
• The output transistors in each amplifier channel
should be checked for damage before applying any
power.
• Amplifier current should be monitored by measuring
across the emitter resistors for each channel.
