CONTROLS AND FUNCTIONS
ON
Lit when the amplifier is on.
SAFE
When lit, it indicates the intervention of protection circuits: in case of
overheating (temperature exceeding 80°C/176°F) or output anomalies (pre-
ence of continuous current, short circuit or dangerously low load impedan-
ce). When protection circuits intervene, the amplifier shuts down. Turn the
amplifier off. When the problem is corrected, turn the amplifier back on.
