Public Address (PA)

Wide experience on Ethernet infrastructures, applied to audio messages distribution, has taken to the realization of very high quality audio systems for on board application, completely based over IP technology (audio VoIP).


Our systems carry out full-duplex communications between all active locations along the vehicle, integrating advanced features of noise suppression (DSP echo cancellers) that ensure the emission of audio announcements and the execution of intercom communications with certified quality.


All our system architectures expose interfaces of backward compatibility towards dated standards still requested (RS485, CANBUS, UIC 568), for a perfect compliance to existing structure under refurbishment upgrades.
