Method 2: Locally Powered Connection Using this method, the intercom station is connected to the intercom line just like any phantom-powered intercom station, except that a local power supply is also con- nected. This local power supply is located right with the intercom station and pro- vides power for that station only. Since power loss on the intercom lines is no longer an issue, the operating range is now limited only by the audio transmission range, which is several miles. Another advantage

Audiocom® Power-Up Make sure any local power supplies are plugged in, and turn on the power switches of any phantom power supplies.
