- 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 work and
make an internal cleaning).
- Short circuit: Check the state of the loudspeaker line (possible short circuit,
disconnect and check if the anomaly disappears).
- DC at the output: Possible serious breakdown. Contact an authorized
technical service.
In all cases it is recommended to go through all previous checkpoints before
contacting the authorized technical service and reporting the observed problem.

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 switch mode
power supply overload.
Note (2): Continuous burst tone 20 ms (0dB) / 480 ms (-20dB) in accordance with EIA RS-490 and
IEC 60268-3 / IHF A-202)
Specifications subjected to change without prior notice (nov 2009)
If you follow the instruction manual and recommendations, we are sure that this
amplifier will always perform within the predetermined parameters, ensuring its long
life and total efficiency.
