SERVICE

Your Soundstream REFERENCE amplifier is protected by a limited warranty

Please read the enclosed warranty card.

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

Auto High

power supply

l

Circuit Breaker on each channel

only)

l

Smart Power Supply Thermal

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.

you experience blown main power supply fuses, it is likely that the

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.
