Description

Ampetronic
Vehicle Systems

There is a growing requirement for assistive listening solutions on-board public transport. Passenger/Driver communication via an intercom is now commonplace in taxis as safety screens become popular and emergency announcements and service broadcasts on tram, bus and train Public Address systems are now part of everyday life.

Hearing impaired users of public transport benefit from hearing loop systems on public transparent as background noise levels are particularly high. For example a direct connection between a user’s hearing aid and a train Public Address system is invaluable when assessing what the next stop is on an unfamiliar route.

Due to their direct connection to the user’s hearing aid(s), Hearing loops are the only ‘Assistive Listening’ technology suitable for use on public passenger vehicles. This is because the users of the service may only be on board for short periods and have no direct access to staff, providing no opportunity to distribute receivers.

Build quality is of paramount importance in vehicle applications due to the inherent vibration and temperature changes that any integrated system will be subjected to. Ampetronic have established products designed especially to overcome these issues and have a proven track record with established manufacturers such as Nissan, Hyundai Rotem, and Ansaldo.

Ashton Audio together with Ampetronic products are used in a range of passenger vehicle hearing loop applications around the world including:

  • Car
  • Taxi
  • Boat
  • Minibus
  • Buse
  • Tram
  • Train carriages/cars.
 
Small Vehicle, VOX Switching Audio Induction Loop Driver, 3.4Arms

The ILD100DC audio induction loop driver is in a class of its own, designed for mobile applications including boats, minibusses, small public transport vehicles and mobile homes. This compact and stylish unit is capable of driving loop areas in excess of 100m2 with an unrivalled clarity of sound for superior intelligibility. Based on proven and highly reliable technology it is backed by a full 5 year warranty and free technical support.

All connections are plug and socket style for simple quick installation. Configuration VOX switching sets priorities for each input. Twin phono (RCA) inputs provide a simple interface to hi-fi systems and televisions. Available with a range of microphones, interface cables and accessories.

Freestanding or wall mounted, the ILD100DC is the obvious choice for smaller installations such as video conference rooms, private homes, TV rooms, nursing homes, receptions and waiting rooms.

Features:

  • Area coverage to >200m2 (SINGLE TURN LOOPS ONLY)

  • Low lifetime cost

  • Excellent proven reliability

  • 5 year warranty

  • Unrivalled intelligibility

  • VOX switching – configured to prioritise Mic 1 input

  • Built in tone control

  • Very compact – 216 x 124 x 44mm

  • 2 microphone inputs (electret)

  • 1 line input – twin phono (RCA) connectors for TV / hi-fi connection

  • Input adaptors and accessories for any audio input requirements,
    e.g. SCART lead, assorted microphones

  • Free technical support line for advice, design and install

 
Applications include:
  • Minbuses

  • Boats

  • Cars

  • Caravans & Mobile Homes

Equipment supplied as standard with the ILD100DC

  • Handbook and installation instructions

  • 99 x 128mm loop system present sign (deaf logo)

  • Region specific mains cable

  • 1 microphone (see options table)

  • 1 SCART to phono cable

Ampetronic can supply an extensive range of additional accessories for installation – discuss your requirements with our sales team and we will provide materials and equipment to suit your application.

Compatible Microphone options

The ILD100DC can be purchased as a stand-alone unit or with microphones. If you require additional options, please contact Support for specification or supply of a microphone to suit your application.

Tie clip microphone EM1.2: Diameter 10 x 18mm long, supplied with tie clip (crocodile clip) and 3m cable. 
Desktop microphone EM195A: Footprint 93 x 76mm. Directional microphone for improved sound pickup. Weighted base for stability. Mounted on horizontal or vertical surface (mounting accessories supplied). 3m cable.
Boundary microphone Q400: AKG manufactured hypercardioid boundary microphone 43 x 23mm footprint. Can be fixed to any flat surface. 3m cable.

Compatible Input adaptors and preamplifiers

By using the appropriate input adaptor or preamplifier the ILD100DC will accept multiple additional inputs or audio inputs from other sources:

MAT60 - Balanced dynamic microphone (XLR) 
MAT60 + 15V PSU - Balanced capacitor 15V phantom power microphone (XLR)
ATT-UJ & ATT-UX transformer isolated attenuators - 100V line input. Low impedance speaker line. Line Level

Standards compliance

The ILD100DC is CE marked to all relevant safety and EMC standards. 
All Ampetronic amplifiers can be used to create a sytem that meets the requirement of IEC118-4 and the relevant recommendation of BS7594. However, the design and installation of the system is equally important to meet these Induction Loop standards

Perimeter Loops – Area Coverage (maximum)

The ILD100DC is designed for cmall vehicles but can be used to drive single turn perimeter loop applications from a 12v power source.

For any Induction Loop System, area coverage is dependent on several factors. Please check these assumptions and contact Ampetronic for advice if required:

  • The loop is 1-2m above or below the receiver height
  • There are no metal structures in the plane of the loop
  • There is sufficient voltage to drive the cable length – check table below.
 
Maximum Cable Length:

The ILD100 is designed for SINGLE TURN loops for optimum audio quality. When maximum current output is required the ILD100 can drive

  • Loops with DC resistance from 0.2Ω to 0.8Ω

  • Impedance up to a maximum of 0.9Ω

When operating below maximum outpuit, the ILD100DC can drive longer cable lengths - contacts us for more details.

Maximum cable length is dependent on cable type and on the application.

* Short term speech (e.g. service counter, airport PA system) can cope with limited clipping at high frequencies – Ampetronic recommends delivery of full current up to 1.2kHz for these applications. 
Longer term usage or signals with music or high quality audio must deliver full current to at least 1.6kHz to prevent fatigue and give acceptable intelligibility. Many commercially available systems do not deliver sufficient voltage to reproduce critical high frequencies – ask us for more details.
