Introduction
Thank you for purchasing Univox® CLS-5T loop amplifier� We hope you will be satisfied
with the product! Please read this user guide carefully before installation and usage of the
product�
Univox CLS-5T is a modern loop amplifier designed for wireless listening through T-coil
equipped hearing devices� The high-current output, essential for optimal signal broad-
casting and wide range of operating voltages,110-240 VAC and 12-24 VDC, supports its
suitability for a number of applications, from on board vehicles to large TV- lounges and
meeting rooms�
Audio quality is significantly enhanced, eliminating modulation distortion at high power
output� The audio chain incorporates also features such as the Metal Loss Correction, to
fine tune for the effects of metal loss, and the unique Dual Action AGC(automatic gain
control) that restores the audio instantly aer noise suppression�
CLS-5T features an alert input which can be activated by vehicles on-board alarm, or - if
installed in a TV-lounge - a doorbell or a telephone�
CLS-5T is certified according to the ECE R10 automotive standard, and correctly installed
provides compliance with all the requirements of IEC 60118-4

User information
CLS-5T should be installed and adjusted by a qualified technician� No maintainance is
normally required� In the event of malfunction, do not attemt to repair the amplifier
yourself�
Mounting and placement
CLS-5T can be wall-mounted (see template for wall mounting at the end of this Installation
Guide) or placed on a flat and stable surface� The wires between the loop figuration and the
driver should not exceed 10 meters and should be paired or twisted�
Important! The placement location must provide adequate unit ventilation.
The amplifier normally generates heat during operation and needs free space for plenty of
ventialtion on all sides�
Installation setup
Two power supply options are avaliable:
• 12-24VDC direct power source
• 110-240VAC External switching power supply
DC power supply connection
12 or 24VDC direct power source connection requires a 5-8A external fuse�
When installing Univox CLS-5T in an application with a DC power supply, if
Unbalanced In 2 is used, a FGA- 40HQ ground isolator (part�no: 286022) must be
installed between the loop amplifier input and the signal source� If the signal source
and the amplifier’s input are not galvanically isolated, a serious error may occur�
1� Connect the loop wire to the amplifier’s loop connection terminal, marked Loop (4�)
2� Connect a suitable input signal source to one of the Inputs, In 1 or In 2
3� Connect the amplifier to mains by using the external power adapter or a 12-24VDC
power source (10�) via 2-p Molex connector (9�)� Observe polarity� Yellow LED (1�)

Default settings
1� Check that there is an input signal, green LED In (2�) illuminated during program peaks
2� Adjust the magnetic field strength to 0dB (400mA/m) in the program peaks� Verify the
field strength with Univox® FSM field strength meter� Check the sound quality with the
loop reciever, Univox® Listener� Some installations require adjustment of treble level�
The treble control is located inside the CLS-5T (single control potentiometer inside
the unit)� When increasing the treble there is an increased risk of self-oscillation and
distortion� Please contact Univox support for guidance�
Special settings for TV connection
• Digital in (11-12.)
Connect with optical or coax cable to TV models with digital input
• RCA/phono (7.)
Connect the TV’s audio output (AUDIO OUT or AUX OUT) to In 3 RCA/phono (7�)
Connecting an alert signal
An alert signal system can be triggered in three ways:
1� External doorbell drive: +24VDC doorbell� Terminal 3-6 on the terminal block
2� External trigger: 5-24V AC/DC� Terminal 4-5 on the terminal block
3� External switch: Terminal 3-4 and 5-7 are shorted separately� The external switch is
connected between 3-4 and 5-7
The acoustic indication supresses the sound in the loop and initiates a broadband harmonic
sound that covers most of the non-linear frequency hearing impairments�

Loop installation guidance
• The installation should initially be planned with a 2 x 1�5mm² paired wire� Connect
the wires in series as a 2-turn loop� If the desired field strength is not achieved,
connect the wires in parallel creating a 1-turn loop� In installations where a standard
round wire is not suitable e�g� due to limited space, flat copper foil is recommended�
• Venues with reinforced structures can reduce the coverage area significantly�
• Analog signal cables should not be placed closely or in parallel to the loop wire�
• Avoid dunamic microphones to reduce the risk of magnetic feedback�
• The loop should not be installed closely to or directly on metal constructions or
reinforced structures� The field strength might be reduced substantially�
• If the shortest side of the loop area is longer than 10 meters, a figure eight loop
configuration should be installed�
• Verify that the overspill outside of the loop is acceptable� If not, a Univox® SLS
system should be installed�
• Relocate any electrical equipment that could create background magnetic field
signals or interference with the loop system�
• In order to avoid feedback from electronic instruments and dynamic microphones, do
not install wire near a stage area�
• A completely installed loop system should be tested with Univox® FSM field strength
meter and certified according to the IEC 60118-4 standard�
• Univox Certificate of conformity, including a measurement procedure checklist,
is avaliable at:
www.univox.eu/support/consultation-and-support/certify-installation/
System check/Troubleshooting
1� Check that the amplifier is connected to the mains power (yellow LED illuminated)�
Proceed to step 2�
2� Check the input connections� The cable between the amplifier and the signal
source/s (TV, DVD, radio etc�) must be properly connected, (green LED “In”
illuminated)� Proceed to step 2�
3� Check the loop cable connection, (blue LED)� The LED is illuminated only if the
amplifier is transmitting sound to the hearing aid and the system is working correctly�
If you are not receiving an audio signal in your hearing aid, verify that the hearing aid
is functioning properly and is set in T-position�
