PROTECTION CIRCUITRY
Your USA amplifier is protected against both overheating and short circuits by
means of the following circuits:
Main power supply fuses.
Speaker output circuit breakers.
A fail-safe thermal protection circuit activating at 95°C.

values beyond the original values! Doing so will void your warranty and may
damage your amplifier.
