The Ampetronic ILD100 audio induction loop driver is in a class of its own. 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 e.g. emergency announcements can override other audio inputs. 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 ILD100 is the obvious choice for smaller installations such as TV loop systems, private home loops, video conference rooms, nursing homes, reception and waiting rooms area loops.

Applications Include:

  • Video conference facilities

  • Meeting rooms

  • Small seminar rooms

  • Television rooms

  • Nursing homes

  • Private homes

  • Receptions and waiting rooms


  • Area coverage to >200m2

  • 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

Perimeter Loops – Area Coverage (maximum)

The ILD100 is designed for perimeter loop applications.
Room aspect ratio 1:1 2:1 3:1
Maximum area coverage m2 120 150 200
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 ILD100 can drive longer cable lengths – contacts us for more details. Maximum cable length is dependent on cable type and on the application.
Cable type Maximum Cable Length (m)
Normal Use* Transient Speech*
1.0mm2 copper 34 39
2.5mm2 copper 40 49
4.0mm2 copper 46 59
1.8mm2 flat copper tape 60 70
  * 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.

ADDITIONAL FUNCTIONS

VOX switching To control prioritisation of microphone 1 input. 4 different actions when microphone 1 level is at the onset of compression. Options to attenuate or turn off other inputs when microphone 1 is active, and to turn microphone 1 off when below threshold if required.
Cooling Cooling is by natural convection from the product casing.
