PROTECTION CIRCUITRY

Your REFERENCE amplifier is protected against both overheating and short
circuits by means of the following circuits:
Main power supply fuses
l
Auto High CurrentTM power supply
l
Circuit Breaker on each channel (Reference414s only)
l
Smart Power Supply Thermal RollbackTM activating at 85°C
l
A fail-safe thermal protection circuit activating at 95°C
l
Your amplifier also incorporates an innovative Fault Diagnosis System that
identifies a blown power supply fuse.
amplifier is seeing a dead short, either in the speaker wire or in the speaker
itself Rectify the problem before blowing mu/tip/e fuses! DO NOT increase
values beyond the original fuse value! Doing so will void your warranty and may
damage your amplifier.
