Wisdom Audio Series SA-3 - Manual (Page 7)

Operating Voltage
For compatibility with existing household outlets, a standard three prong, 20
ampere plug is provided on the removable, IEC-standard AC mains cable.
The Wisdom Audio SA-3 may be set for 100V, 120V, or 230V/240V AC mains
operation. Outside the United States, and depending on local electrical codes
and regulations, the AC mains cord may need to be replaced with one that con-
forms to local plug/outlet standards.
Note that the AC receptacle employs a 20-amp IEC-standard socket
(not the more common 15-amp IEC socket).
The operating voltage of the SA-3 may not be changed by the user. Your ampli-
fier has been preset at the factory for the voltage of the country for which it was
built. If you move to a country with a different AC mains voltage, please contact
your local Wisdom Audio distributor or Wisdom Audio for assistance.
Caution! Always make certain the SA-3 is set to the correct voltage before
connecting it to AC mains power! Failure to do so can severely
damage the unit and void the warranty.
This power amplifier has an extremely large power supply, and consequently
includes a special protection circuit that protects your AC mains circuit from ex-
cessive in-rush currents when power is applied to the unit.
Caution! Please allow thirty seconds between turning the unit On and Off, or
toggling between Operate and Standby, to ensure that the in-rush
protection circuit has an opportunity to reset itself properly.
Failure to observe this procedure may result in nuisance tripping of the AC
mains supply’s circuit breaker. If this should happen, disconnect the amplifier,
reset the AC mains supply’s circuit breaker, and wait for two minutes before re-
connecting the amplifier to the AC mains.
