Use the existing cabling in a simple and monument-friendly way.

It has never been easier to turn old into new.

Power supply, audio data and control - all over a conventional two-wire cable as found in a classic, passive speaker setup or a 70/100V installation. This is made possible by our in-house developed Pan Acoustics Pan 2-Line technology, which transforms a passive sound reinforcement system into an active solution.

The highlight: the active, digitally controllable line array loudspeakers from the Pan 2-Line series can be integrated directly into the existing cabling of the previous installation. The building fabric remains untouched. This is ideal for the preservation of historical monuments and it reduces total system costs.

The PB 04-P2L is a compact, active, digitally controllable line source with Beam Steering and Pan 2-Line technology in an attractive design, developed for high-quality speech and music transmissions. The PB 04-P2L features Pan Audio DSP and Pan 2-Line technology. With this technology, audio, control data and the power supply can be transmitted over two wires (2-wire) such as speaker cables or cables of an already existing 100V installation. A Central Control Unit (CCU) is required to feed the signals and the voltage.
