KeTech Wireless Public Address System Given the cost and inconvenience of installing Public Address cabling The key advantage of a wireless system is that it requires no between railway platforms; KeTech has designed a solution that along platform cabling, no cross-track cabling and no in-cabinet provides wireless audio transmission between railway platforms direct to wiring, resulting in significant cost and time savings and limited individual speakers. operational disruption during installation. KeTech’s digital wireless Public Address system operates in the same This pioneering technology from KeTech provides a unique way as current railway PA systems, with automated announcements, opportunity for stations to renew speakers and install a new real time driven announcements and live announcements being made digital PA system without the disruption or expense of having to through a local or central control system. However, unlike existing replace the central PA. The system incurs no licence fee, is systems, the KeTech wireless unit will take a line level audio signal from easily scalable, can be mixed and matched with wired systems the local controller and transmit to the receiver / speaker combination and provides independent addressable speakers and zones. In installed along the platform or in the concourse areas. The system all, a very versatile, cost effective and easily implemented provides a digital transmission path for interference free high quality solution for railways. audio. Suitable for small to medium applications, the KeTech system can be tailored to local site coverage by suitable antenna selection. KEY BENEFITS › Requires no cross track cabling (no UTX) › Digital system for noise free transmission Scalable solution suitable for small to medium systems › Operates in licence free frequencies › Scalable solution- suitable for small to medium systems › Standard audio interface › Plug-and-play audio interface › 230VAC/14VDC operation (derived locally) KeTech.com The transmitter can be conveniently located near a Control Room and requires only audio (& zone data in required) and DC power. The combined receiver /speaker units are typically located on lighting columns or in the concourse area from where power is locally derived. The KeTech wireless PA system accepts standard line level audio signals and is easily linked to standard audio sources.
