AC Power Cord Polarity
Rear Panel, Nº390S
1. AC power input and switch
This input accepts AC power from the AC mains (via the sup- plied AC cable).
The Nº390S is set internally for 100, 120, 200, 220, or 240VAC mains operation at either 50 or 60Hz. Make sure that the label on the bottom of the unit indicates the correct AC operating voltage and frequency for your location before connecting it to AC mains.
Connect the female end of this cable to the Nº390S. Connect the male end of this cable to wall outlet or to an “unswitched” convenience outlet like those found on some audio components.
Turn on the power by pressing the top of the power switch above the power cord receptacle (it has a solid vertical line to indicate “on”: ).
