Pan Powerline means the transmission of audio signals, control data and power supply via two electrical wires. The two-wire-system in its capacity as transfer medium can almost be applicable for any purpose. Only the ohmic resistance should allow the electricity power. This means that old cables such as bell-wire or 100V-cable can be used further.

A Pan Powerline system consists of a master unit called Central Control Unit (CCU). This central unit mixes the audio input signals with control data and the power supply together. A CCU can manage up to four Powerline loudspeakers. Several types of speakers such as PB 08-PPL or PB 04-PPL can be connected to a line while each speaker can be adjusted through various parameters e.g. frequency response, beam steering and delay. An integration of the system within a media control is also possible. The speaker can be arranged and operated in star-shaped system, in a star-daisy chain or in a daisy chain wiring.
