2.7 Connect to AC Mains
Connect the AC power cordset of your amplifier
to the AC mains power source (power outlet).
NOTE: The third prong of this connector
(ground) is an important safety feature. Do not
attempt to disable this ground connection by
using an adapter or other methods.
Amplifiers don’t create energy. The AC mains
voltage and current must be sufficient to deliver
the power you expect. You must operate your
amplifier from an AC mains power source with
not more than 10% variation above or below the
amplifier’s specified line voltage and within the
specfied frequency requirements (indicated on
the amplifier’s back panel label). If you are
unsure of the output voltage of your AC mains,
please consult your electrician.
