3. INITIAL POWER ON AND OPERATION

After following all instructions in Section 2 INSTALLATION, check whether the rear panel mains switch

is turned off. Then plug the amplifier in the mains outlet.

Now you can turn on the mains switch on the rear panel. This will activate only the low-energy stand-by

mode of the amplifier power supply and will light up the red LED above POWER button, while the main

Do not turn the amplifier on at least two hours after unpacking it

and installing in its final operating position. Pay special attention

whenever the amplifier is moved from a very cold place to a very

warm one because condensation may develop on the inside

resulting in damage to the high voltage circuits of the amplifier.

Under these circumstances, do not turn the amplifier on for at least

4 hours. A similar effect could occur following a rapid warming of

the room, such as winter usage of a powerful electric heater.
