The public address system is a mean of delivering voice information over large areas. Depending on the information
and the area to cover the PA specification may require a means to transport the signal large distances.
A Long-line public address (LLPA) system is any public address system with a distributed architecture, normally across
a wide geographic area. Systems of this type are commonly found in the rail, light rail and metro industries and allow
announcements to be triggered from one or several locations to the rest of the network. Traditionally LLPA systems
use low bandwidth legacy copper, normally PSTN lines using DSL modems, or media such as optical fiber, or IP-based
networks.
Inter-M has developed solutions to transmit High quality uncompressed multi-channel audio and control over TCP/IP
networks, dedicated copper lines and Optical fiber cables. High quality digital voice and BGM signal can be transported
over long distances using Inter-M’s FTA/FRA-108S, ITX/IRX-108, ITX/IRX-102 products.
FTA/FRA-108S will transport high quality 8-channel audio signals, serial data and contact closure triggers over long
distances (up to 24km) using Single-mode fiber-optic cable.
ITX/IRX-102/108 will transport high quality 2 and 8-channel audio signals, serial data and contact closure triggers over
relatively short distances (up to 100 meter) using standard cat5e cabling.
These products will transport high quality uncompressed audio signals combined with data and contact triggers with
very short and relatively small propagation delay of 1.0 ms.
As the requirements of public address systems changes the R&D engineering team of Inter-M is ready to deliver new
innovative products to meet market and systems demands.
