Description
The DLC20-65 kit is the ideal equipment for counters or reception desks allowing audio accessibi
lity for people with hearing loss. This product is for all Public-facing establishment. It has the
advantage of being one of the most compact and discreet of the market allowing optimal
integration results. It offers especially a perennial installation.
Therange
We are pleased to introduce our new brand Opus Technologies designed and manufactured in
France. We propose innovative products offering maximum comfort for the users.

DCL20-65
The DCL20-65 is an induction loop kit that can be used to equip counters or reception desks.
The system allows to meet the restrictions of the law of european equal treatment directives
while respecting the requirements of EN60118-4. The set is designed to offer accessibility to
hearing- impaired equipped with a T-position on their hearing aid.
The amplifier is designed to be discreetly attached under a desk or counter. It is equipped with
two inputs, settings and LEDs indicating the presence of power supply and loopcurrent.
The device incorporates an audio processing to have an automatic control of the sound levels,
avoiding loud and suddennoises.
Safety notes
The majority of problems with the hearing loop loop happens when the installation has not
been properly reflected so let's take a while before starting the installation to better results and
time saving.
Ideally, the loop amplifier should be placed near the area to be covered. This may involve
placing the amplifier on a panel, under a desk or under a table.
The pickup microphone should be as close as possible to the input of theamplifier.
To position the loop in the space to be equipped, it is important to take into account the final
users of the system.
For example, if the place is planned for a con- versation between a speaker and a client, a loop
around the desk may be a better solution rather than a loop around the perimeter of the
room. It will limit radiation and increase confidentiality.

This kit includes:
A DLC20 amplifier
A power supply
A power cord
A 1,80m loop cable
Three 2-point connectors
One 3-point connectors
A set of 2 stickers « space adaptedfor hearing impaired».

Installation
Composition and assembly ofthe loop
The loop consists on the following 3 elements: a loop cable, a loop adapter and a connecting
cable.
The loop is ready but it is possible to disas- semble it to adapt it to the reception desk. See
below.
To disassemble the loop that will equip the counter, first unscrew the support of the elec- tronic
card.
Connect the beginning and the end of theloop cable to the circuit board (red connector).
Then plug the 50-70 cm connecting cable sup- plied to the "amplifier" connector of the adap- ter
and to the "Loop" terminal block of the am- plifier.
Your loop is now created andconnected.
Installation of the loop in the coun-
ter
1. There are 2 possibilities to place a loop in
a counter as described below, however we
strongly advise you to use the first
version:Place the loop on the vertical and
horizontal portion of the counter as shown
in figure 1. This type of installation ensures
better coverage in front of the counter. Figure1.
Note:
The wire supplied in the DLC20-65 kit ensures the quick installation of a magnetic
loop system in a reception desk, counter or cash desk.
In order to optimize the radiation of the magnetic field and to guarantee a
. better result he wire should be placed close to thecustomer.

2.Position the loop on the horizontal counter-
top by positionning the cable closest to the
customer.
3.Install the loop on the vertical countertop by
positioning the cable closest to thecustomer.
Set the loop using the binding clips supplied for this purpose. For better durability, it may be ap-
propriate to install the loop in a plasticchute.
Then connect the connecting cable to the termi- nal block "amplifier" of the connector on the
terminal block "loop" of theamplifier.
Screw the connector on the cross.
Attention, warning, danger:
The loop must not be positioned
under a metal structure. The ma-
gnetic field would be absorbed by the
metal mass and would not equip
the counter properly. There are
other solutions for installing a loop in ametal
counter (see figure 3)
For greater coverage around the counter, it is possible to install a cable on the floor. The loop can
be placed in the slab (over the wire mesh), under a coating (parquet, carpet, ... etc) using a
copper tape or glued under a carpet as shown in figure 3 .
Figure3.
The wire supplied in the DCL20-K kit produces a
magnetic field radiating on a perimeter of 1.2m
which allows a people to receive the signal
com- fortably.

fixed on the desk and turned to the customer’s
side to avoid disturbances due to metal (see

Explication
The wire forming the loop are connected to an audio amplifier. The hearing aid often called "T" or
"T-coil" which is placed inside spirale wire. The magnetic field generated by the large loop will
cross the coil and, by the induction process, the electrical signal present in the large loop will be
found in the one small. The signal of the audio amplifier is transmitted to the hearing aids, which
will then restore it to the ear of the impaired ones.
The loop can be installed in the floor or at the roof level, more precisely between 1.10m and
2.20m from the listening height(ears).
The presence of an hearing loop is often indi- cated by a blue logo representing a crossed out ear
and a letter T. Generally, a hearing aid has two major positions, the M and the T. The position M
makes it possible to perceive the sound thanks to sound pressure as a microphone, while the
position T (T for telephone) directly receives the audio signals transmitted by induction via the
integrated coil. Some aids combine these two modes of operation with the MT position. It allows
the hearing impaired to perceive both ambient noise and inductively transmitted signals.
