Low-Voltage (DC) Power Connection

Your Source speakers use external low-voltage power sup- plies to energize their electrostatic panels. For this reason the proper low-voltage power supplies are provided. A power supply should be firmly inserted into the ‘DC Power In’ receptacle on the rear connection panel of each speaker, then to any convenient AC wall outlet. Your Source speak- ers integrate a signal sensing circuit which will switch the Source off after a few minutes of no music signal, and requires less than two seconds to recharge the panels when a music signal is present.

Your Source speakers are provided with a power supply for the power service supplied in the country of original consumer sale. The AC power requirements applicable to a particular unit is specified both on the packing carton and on the DC power supply.

If you remove your Source speakers from the country of original sale, be certain that the AC power supplied in any subsequent location is suitable before connecting the low- voltage power supply. Substantially impaired performance or severe damage may occur to a Source speaker if opera- tion is attempted from an incorrect AC power source.

WARNING! The DC power supply should not be installed, removed, or left detached from the speaker while connected to an AC power source.
