PROTECTION CIRCUITRY
Your REFERENCE Class A amplifier is protected against both overheating and
short circuits by means of the following circuits:
l
Main power supply fuses
l
Smart Power Supply Thermal Rollback activating at 85°C.
l
A fail-safe thermal protection circuit activating at 95°C.
Your amplifier also incorporates an innovative Fault Diagnosis system that
identifies a blown power supply fuse.
NOTE: If you experience blown main power supply fuses, DO NOT increase
values beyond the original fuse value! Doing so will void your warranty and
may damage your amplifier.
