The ENA2060-DC1 Network Amplifier for Rolling Stock incorporates SIP-addressable loudspeaker loops that enable the use of the same software for handling both Passenger Emergency Intercom / Crew Communication and Public Address (PA), as well as the required Train Radio Integration, thus eliminating one entire subsystem from the solution. This results in a well-integrated system with less complexity and more functionality, while the use of open standards offers freedom of choice when it comes to future upgrades and supply.

A modern on-board system normally features an IPBX with SIP capability for emergency call points and their radio integration. The IPBX can be based on proprietary or an open source software architecture that runs on EN50155 approved hardware. Given the usual requirement for on-board PA, the IPBX can easily handle the function of being the PA controller. A complete PA System can thus be provided just through the use of an EN50155 approved SIP amplifier. Eliminating one entire proprietary subsystem not only
reduces the total system cost, but also time spent in integration work. Moreover, a clean and robust integration means enhanced passenger safety.

The ENA2060-DC1 Network Amplifier is intended to cover one carriage consisting of two or more PA zones. Examples of such zones can be the left and right side of the carriage, upper and lower deck, or even outside speakers. Redundancy can be achieved by using two amplifiers which ensure that at least 50% of the loudspeakers will still work in case of a failure in one IP PA amplifier (A-B amplifier setup). Hence, public address announcements will still be audible with only a minor drop in sound pressure level.
