T14-1 Transport hearing loop driver – Rail

The T14-1 Rail transport hearing loop driver offers:

  • Compliance to relevant rail standards EN50155, EN50121-3, EN45545
  • Cover a whole carriage with a single amplifier
  • Unrivalled intelligibility

Service broadcasts and emergency announcements through rail and tram Public Address (PA) systems are now part of everyday life. Their direct connection to the user’s hearing aid means that Hearing Loops are the only assistive listening technology suitable for use on public passenger vehicles. The T14-1 Rail transport hearing loop driver from Ampetronic offers performance you can rely on:

  • Generating less heat than other drivers in its class
  • Remote technical support and network features to control and configure the system
  • Enables reporting features to be integrated with the TCMS
  • Metal Loss Correction
  • Low lifetime cost
  • Excellent reliability backed by a 5 year warranty

The T14-1 replaces the XA88 and is also available for bus and coach transport (see T14-1 Bus transport hearing loop driver) The T14-1 hearing loop driver range has been designed as high quality digital, networkable single loop output drivers. The range includes models intended for use in rail or bus applications. Depending on a number of factors regarding the installation of the loop and the set-up of the driver, the T14-1 range can provide compliance with IEC 60118-4 for appropriately specified loop installations. Compliance to relevant Standards, reduced weight and heat generation have been major factors in the design, combined with optimised performance and the freedom from R.F.I. generation. The T14-1 range has a Class D output stage which offers better than 60% increase in energy efficiency over previous solutions. The products feature WAGO or Harting connectors and use remote control and monitoring via a browser based control panel using standard network protocols; including HTTP, Telnet, email and SNMP. All units feature high power outputs plus ample voltage headroom, making them suitable for any rail, tram or bus application. Networked T14-1 models also feature dual-slope metal loss compensation that caters for a wide range of metal loss frequency characteristics.

  • Class D output stage driver for maximum efficiency, unsurpassed in its field
  • Less weight than most alternatives in its class
  • Options to allow analogue and VOIP audio inputs
  • Transformer isolated inputs
  • Industrial Ethernet port
  • USB firmware update port
  • T14-1LW: 24V power, Wago connectors
  • T14-1LH: 24V power, Harting connectors
  • T14-1UW: 72-110V power, Wago connectors
  • T14-1UH: 72-110V power, Harting connectors
