Induction Loop Mode
The Minilyzer simplifies verifications and adjustments of AFILS (Audio
Frequency Induction Loop Systems). AFIL systems are used in public
buildings to increase the speech intelligibility for users of hearing aids.
Most hearing aids have a built in magnetic coil receiving audio signals
generated by induction loop systems. AFIL systems consist of a wire loop
and a current amplifier generating a magnetic field into the hearing aid,
modulated by the audio input signal, e.g. voice.
Adjustment and verification of AFIL systems is described in the IEC 60118
standard. The Minilyzer, together with an induction loop receiver, is an ideal
tool to accomplish the necessary measurements.
Induction Loop Receivers
There are various induction loop receivers available from different AFILS
components manufactures. All known types work together with the ML1.
Some receivers have a built in A-weighting filter, which must be disabled to
prevent measurement errors.
Activation of the Induction Loop Mode

After this the ML1 restarts in the induction
loop measurement mode. To return to the
common ML1 measurement mode, disable
the induction loop mode in the setup page
again.
Enter the setup page of the ML1
Change the position “Ind. loop mode” to
“ENABLE”
