Audio & Data Transmission Solution

Development Background

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.

over TCP/IP network with a S/N better than 100dB, THD less than 0.01.

THD : Total harmonic distortion stands. The lower THD means that the equipment produces a more accurate reproduction by reducing

harmonics added by electronics and audio media

S / N Ratio : Stands for Signal to Noise Ratio expressed in dB. It is a measurement that compares the level of a desired signal to the level

of background noise. It is defined as the ratio of signal power to the noise power. The higher the ratio indicates more signal than noise.

FEATURE

Data tunneling

Control of Local and remote equipment is possible using the built in eight programmable trigger inputs to

initiate and terminate audio transmissions, eight programmable open collector control outputs as well as

the RS-232 and RS-422 serial port for data transmission/reception with communication speeds of up to

19200 bps.
