Operating Voltage
For compatibility with existing household outlets, a standard three prong, 15
ampere plug is provided on the removable, IEC-standard AC mains cable.
The Wisdom Audio SW-1 will operate with 100V–240V AC mains operation.
Outside the United States, and depending on local electrical codes and regula-
tions, the AC mains cord may need to be replaced with one that conforms to
local plug/outlet standards.
