3.4ARMS, for areas up to 200m2
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
Equipment supplied as standard with the ILD100
- Handbook and installation instructions
- 99 x 128mm loop system present sign (deaf logo)
- Region specific mains cable

Compatible Microphone options
The ILD100 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: Directional microphone for improved sound pickup. Weighted base for stability. Mounted on horizontal or vertical surface (mounting accessories supplied). 3m cable.
Boundary microphone: hypercardioid boundary microphone. Can be fixed to any flat surface. 3m cable.
Compatible Input adaptors and preamplifiers
By using the appropriate input adaptor or preamplifier the ILD100 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

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.

* 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.
