Soundstream Reference 200 - Protection Circuitry & Troubleshooting; Service

PROTECTION CIRCUITRY
Your REFERENCE 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 b/own main power supply fuses, DO NOT increase
values beyond the original fuse value! Doing so will void your warranty and
may damage your amplifier.
