AFIL / AFILEB
Induction Loop Amplier Modules for barrier-free communication
Commend – Communication and security for everyone
The Audio-Frequency Induction Loop amplier modules AFIL and AFILEB
bring existing equipment up to the latest standard of „barrier-free communica-
tion.“ This is regulated by various standards (e.g. IEC 60118-4), with the aim of
ensuring perfect communication. In combination with an induction loop, the
AFIL / AFILEB modules provide direct communication to hearing aids in well-
known excellent Commend quality.
The small size and the availability in two different versions (with housing AFIL
and without housing AFILEB) allows for exible integration into environments
such as ticket vending machines, barriers, and help points.
Features and Highlights
– A fully integrated, IEC 60118-4 compliant induction loop system enables
wearers of hearing aids to receive Intercom audio signals in clear, uninter-
rupted quality.
– Flexible integration in environments, e.g. ticket vending machines, ser-
vice counter, barriers, and help points
– Energy-efcient and power-saving technology with low heat generation.
– Functions as MLC (Metal Loss Correction) and AGC (Automatic Gain
Control) for easy startup and faultless operation.
– Compatible with virtually all Commend Intercom Terminals and Intercom
Modules or third-party audio sources.
– All connections to a single face for installation convenience.

Installation / Measurements
Mounting instructions
– Do not expose the station to extreme temperature (see “Technical Data“ on page 2).
– Observe the country specic standards for installation, mounting and conguration.
– When opening the stations ESD precautions must be observed.
– The housing may only be opened by authorised service engineers.
– Induction Loop Performance compliant with IEC 60118-4 (when correctly installed)
– Metal Structures signicantly affects performance of the induction loop system. The magnetic eld generated by an induction loop system,
induces a current in any closed path of a metal structure placed in the vicinity of the induction loop. These induced currents tend to weaken the
magnetic eld and cause loss.
Examples of metal structures:
– Lightweight oor construction with a (usually proled) metal sheet under a thin reinforced concrete slab.
– Girders, beams, constructional metal work
– Metal cladding and walls
– Metal box construction (elevators, lifts)

Please follow the following instruction for the installation of the Induction Loop Amplier Module:
– Mount the induction loop (not in the extent of supply) - for the mounting of the induction loop please consider the respective norm.
– Mount the Induction Loop Amplier Module - it is recommended to combine the amplier with an Intercom module ET 908A or ET 808A or to mount the
induction loop amplier in a separate housing.
– Turn all potentiometers fully anti-clockwise.
– Carry out the connection of the induction loop, signal input and power supply
– Connect the loop cable (polarity does not matter) as shown in the following picture.
– Connect the signal input with a twisted pair or shielded cable. The cable can be connected via the screw terminal or the JST plug (type: PAP-02v-s) as
shown in the following picture.
– Connect power supply (15 VDC - 26 VDC) as shown in the following picture.
– Switch on the external power supply and check if the green “Power” LED illuminates!
– Apply input signal (e.g. by speaking into mic) and increase the level with potentiometer “Level -Input” until the LED “
Adjust
” begins to light green.
– Increase the potentiometer “Loop Current” until the LED “Adjust” begins to light orange.
– With the potentiometer “MLC” it is possible to compensate the metal loss.
Note: Increase the potentiometer to compensate the metal loss. If the potentiometer is turned fully anti-clockwise, no metal loss correction is active.
– Test the performance of the system using a loop receiver or eld strength meter and adjust “MLC” & “LOOP CURRENT” to achieve acceptable performance
- please consider the respective norm!
