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.
