PROTECTION CIRCUITRY

Your SA amplifier is protected against both overheating and short circuits by means of the following circuits:

•Main power supply fuses.

•A fail-safe thermal protection circuit activating at 95°C.

•Self-resetting circuit breakers to protect against short circuits.

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.

TROUBLESHOOTING

PROBLEM		CAUSE
No sound and LED is not lit	•	no power or ground at amp
	• no remote turn-on signal
	• blown fuse near battery
Repeatedly blown amp fuse,	•	check speaker configuration-
frequent activation of Thermal		impedance may be less than 2
Protection Circuit		ohms stereo or 4 ohms mono
	• speaker or leads may be shorted
	•	verify adequate amplifier
		ventilation
No sound from channels 3 & 4 with	• check input settings on bottom of
2 channels of input		amplifier-switch should be set to
		inputs “1 & 2”
Channels cut in and out	•	circuit breakers are activating.
		Check for a possible short in the
		speaker wire or in the speaker
		itself
	• verify that the impedance of the
		load is at or above the minimum
		rated impedance

SERVICE

Your Soundstream amplifier is protected by a limited warranty. Please read the enclosed warranty card.
