Other causes that could prevent the normal work of the amplifier
can also activate the PROTECTION. Under those circumstanc-
es, the installation has to be revised according to the basic prin-
ciples described below:
- Disconnect all the connected peripheral equipments
(sources, pre-amplifiers, and loudspeakers). Leave the amplifier
"alone" and verify if the anomaly disappears or if it remains in
only one channel or both.
- Temperature: Cooling (possible air obstruction. Check if
the fans are working and make an internal cleaning).

Note (1): Driving the amplifier at 2 ohms channel / 4 ohms bridge mode in poor ventilation conditions may cause
a thermal overload protection. 2 ohms power is time limited by main circuit breaker.
