Public Address System WM-ELISA II on Interface Connection Inclusive With ISDN Gains EBA-Typzulassung
Elmshorn, 4 February 2008
Recently, the remote PA system WM-ELISA II - enabling to operate public address via ISDN as well - has been authorized by EBA.
Thus the WM-ELISA II can be interfaced in different way via
- VoIP
- LF I/O
- ISDN
according to equipment level 1 or 2.
Due to the combination of these interfaces the PA system WM-ELISA II can be used extremely flexible. It allows to build up systems with redundant transmission lines so that in case of connection failure, e.g. in the IP area, the public address can be managed anyway. Furthermore you can connect existing PA equipment to WM-ELISA II via LF I/O.
