ILA-1000
The ILA-1000 Induction Loop Amplifier for audio transmission is widely used to provide hearing aids with inductive audio signals.
Compatible with the requirements acc. to EN 60118-4.
The 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 optimum performance.
Induction loop amplifiers are very often used in churches, cinemas, theaters, outlets, bank counters, interpreting systems or DRIVE-INs or DRIVE-THROUGHs so that hearing aid wearers can hear much better in severe acoustic conditions (background noise, reverberation, etc.) without disturbing noises.
The ILA loop amplifier is used wherever an induction transmission is installed.
The amplifier is also particularly suitable for people who need a high quality "wireless hearing aid" without having to use a real hearing aid, such as in channel interpreter systems.
USEFUL INFORMATION
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. A purely acoustic, direct sound transmission (between loudspeaker and hearing aid) due to reverberation and background noise substantially worsens the perception of the useful signal by the hearing aid wearer.
