(a) If no protections has occurred.
NO PROTECT
(b) ASO (if the last protection is ASO)
PRT:ASO
Cause A short circuit occurred between the speaker terminals, or speakers with an impedance outside
the rating were connected.
Note : Short circuits in speaker terminals or speakers can be identied.
If the power is turned on in the abnormal state, protection is activated after around 6 seconds and the
power is turned off.
(c) DC (if the last protection is DC)
PRT:DC
Cause : DC output of the power amplier is abnormal.
If the power is turned on in the abnormal state, protection is activated after around 6 seconds and the
power is turned off.
(d) THERMAL (if the last protection is THERMAL(A) or THERMAL(E) or THERMAL(F) )
PRT:THERMAL A
PRT:THERMAL E
PRT:THERMAL F
Cause : Abnormal heat sink temperature.
If the power is turned on under abnormal conditions, the protection function works immediately and
the power is turned off.
(e) Case of CURRENT (when the last protection incident is CURRENT protection)
:CURRENT
Cause : An over current owed in power amp.
If the power is turned on in the abnormal state, protection is activated after around 90 seconds and the
power is turned off.
Caution : These protections may also be activated due to other factors such as disconnection of connec-
