CONNECTIONS 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.
