signal path which can degrade the signal by compressing dynamics. The
CAP5 system operates outside the signal path and when triggered shuts
down the amp rather than limits the size of the signal passing through
the amp (signal compression). V/I protects the amplifier against short
circuits on the speaker terminals during use.

540A/640A Integrated amplifier
Fault/Remedy
CAP5 has detected that the resistance on the Loudspeaker terminals is
too low. Check to see if there is a short circuit between the Loudspeaker
terminals.
Note: If the indication remains the same and multiple Loudspeakers are
being used on each Loudspeaker output then please remove a pair and
retry. If too many Loudspeakers are connected to any amplifier causing
the Load resistance to drop too low the amplifier will overheat. CAP5 will
detect this situation.
If the indication remains the same with only one set of loudspeakers
connected then there could possibly be a fault with one or both of the
loudspeakers.
CAP5 has detected a user related fault, the internal temperature of the
output transistors has reached the over temperature limit. The unit is not
damaged although it should be left for 15 minutes to cool down before
being switched out of standby.
CAP5 has detected a user related fault, there maybe a short circuit
between the loudspeaker terminals. Please check all Loudspeaker
connections before attempting to switch unit out of standby
CAP5 has detected a fault which requires the unit to be serviced. DC has
been detected on the output of the amplifier which could damage the
speakers. The amplifier is now unusable. Please switch off and contact
dealer.
