ILA-1000
™
The ILA-1000 Induction Loop Amplifier for audio transmission is widely used to provide hearing aids with
inductive audio signals.
The ILA-1000 Phoenix Induction Loop Amplifier was developed as a high-quality LOOP amplifier for medium
induction loops.
The system is characterized by its easy installation and customer-oriented operation with optimal performance.
Induction loop amplifiers are very often used in churches, theaters, outlets, libraries, press rooms, lecture
halls, courtrooms, bank counters, interpreter systems or DRIVE IN / DRIVE-THROUGHs so that hearing aid
wearers can hear much better in severe acoustic conditions (background noise, reverberation etc) without
disturbing noises.
System advantages:
Due to the inductive coupling of hearing aids, the useful signal (audio transmission) can be heard much better
without disturbing noises. By transmitting an audio signal through the induction loop, an acceptable signal-to-
noise ratio is achieved.
Useful Information:
A purely acoustic, direct sound transmission (between loudspeaker and hearing aid) due to reverberation and
background noises considerably worsens the perception of the useful signal by the hearing aid wearer.
Receiver ILA-E:
The ILA-E Induction Loop Receiver makes it easy to quickly and easily check or maintain a loop system.
The ILA-E loop receiver is used wherever an induction transmission is installed or particularly suitable for peo-
ple who need a high quality „wireless“ hearing aid without having to use a real hearing aid, such as in channel
interpreter systems.
Planning the loop design:
Not everywhere where it would be desirable acceptable or good conditions for the installation of the induction
loop can be found. Therefore, it is necessary in the planning phase to examine a proposed location in terms of
the following conditions:
- Magnetic interference of electrical systems, for example, heating systems in the floor or in the roof area and
electronic controls of lighting systems (especially in cinemas, theaters, etc.).
- Influence of magnetically or electrically conductive materials in the building structure, especially where the loop is
to be laid.
- Presence of other induction loops in the neighborhood whose signals can interfere with those of the scheduled loops.
