You should observe all precautions in accordance with national legislation.
The amplifier is supplied by a power supply that automatically adapts between 100 and
255 VAC, 47-63 Hz.
In some particular cases, mains that are 100 to 120 VAC, the power in MAX may be
reduced somewhat.
In the case of a "FATAL" alarm, the power supply is locked. To restore the linear, switch
it to OFF for about 30 seconds, via the rear switch, then back ON.
If the alarm persists, contact the Distributor.
Note: In some conditions it is possible to perceive a small "hiss" coming from the power
supply. This sound must not worry you because it is the action of the PFC, essential
circuit mandatory in the CE area, to optimize the efficiency of the power supply and
to reduce the introduction into the mains of noise generated by the request for high
power.
The PFC takes into account not only instantaneous load requests but also
the momentary conditions of the mains itself.
