    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. NOTE: If you experience blown main power supply fuses, DO NOT increase values beyond the original values! Doing so will void your warranty and may damage your amplifier.
