Electrodynamic sound emitter for warning and public address (PA) applications.
In combination with Control Cabinet TK 1000 the Delta allows the maximum acoustic propagation on the horizontal plane, and excellent omnidirectional radiation.
A high acoustic efficiency is achieved through the unique design of the horns and the integrated compression elements.
The materials of the emitter have been chosen to withstand all clmates, from arctic to tropical. The device is totally maintenance-free. It is equally simple to fit to a house facade, house roof or freestanding mast. CE-labelled and complies with Directives 73/23/EEC and 89/336/EEC.
