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 LevelStandards complianceThe ILD100 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 ILD100 is designed for perimeter loop applications.
Room aspect ratio
Maximum area coverage m2
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.
Maximum Cable Length (m)
1.8mm2 flat copper tape
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.
