When there is no history of protection function:
Notes)
• Applying the power to this unit without correcting the abnormality can be dangerous and cause additional circuit dam-
age.
To avoid this, if “PRI” and “PRD” protection function has been activated 3 times continuously, the power will not turn
on even when the “STANDBY/ON” key is pressed.
In order to turn on the power again, disconnect the power cable of this unit from the AC outlet once and then recon-
nect it again.
• The output transistors in each amplifier channel should be checked for damage before applying power to this unit.
• Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.
When there is a history of protection function due to abnormal DC output
When there is a history of protection function due to excess current:
Cause:
DC output of the power amplifier is abnormal.
Supplementary information:
The protection function worked due to a DC voltage appearing at the speaker terminal.
A cause could be a defect in the amplifier.
If the power is turned on with the abnormality unsolved, the protection function works in about 3 seconds to turn
off the power.
Cause:
An excessive current flowed through the power amplifier.
Supplementary information:
As current of the power amplifier is detected, the abnormal channel can be identified by checking the current de-
tect transistor.
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.
