Operating Precautions
Make sure the AC mains voltage is correct and is the same as that printed on the rear of the amplifier.
Damage caused by connecting the amplifier to improper AC voltage is not covered by the warranty. Make
sure the power switch is off before making any input or output connections.
It is always a good idea to have the gain controls muted during power-up to prevent speaker damage
particularly if there is a high signal level at the inputs.
Whether you purchase them or build them yourself, use good quality input and speaker cables. Most
intermittent problems are caused by faulty cables. Use good quality connectors and cable along with good
soldering technique to ensure trouble free reliability.

AC Main connection
Warning: before connecting to mains be sure that the amplifier is set to the correct mains voltage.
The AC Main connection is made via the IEC type connector on the rear panel. The picture below shows the
connection to the amplifier. Be sure that your AC mains power source has the requirements indicated in this
manual. The amplifier is a resistive load for the mains network, minimizing the reactive power and the
harmonic distortion on the current. The system allows performance to be maintained even in circumstances
of varying the mains voltage.
Is important to connect the ground for safety, do not use adapters that
disable the ground connection.
