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 broadcasting 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 after 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 3 Connections and controls CLS-5T Front panel Overview Rear panel Side On 12-24V DC Loop Current Developed in Sweden by Bo Edin AB www.univox.eu 1 10 9 6 11 12 1 2 3 4 5 6 7 8 9 10 4 13 5 7 3 8 2 4 Description 1 On/Off Yellow LED indicates mains power connection 2 In LED Green Input 1 and 2 Indicates signal source connection 3 Loop LED Blue Indicates that loop is transmitting 4 Loop connection terminal, pin 1 and 2 5 In 1 Balanced line input, pin 8, 9, 10 6 Loop current adjustment 7 In 2 RCA/Phono 8 In 1, volume control 9 12-24VDC supply (see polarity below) 10 110-240VAC, external switching power supply 11 Digital input, optical 12 Digital input, coax 13 Alert signal system, pin 3 through 7 - see pages 7-8 'Connecting an alert signal' 5 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 (partno: 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) illuminated + - Molex connector polarity -+ 6 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 7 Loop installation guidance · The installation should initially be planned with a 2 x 15mm² 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 eg 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 dynamic 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 8 Safety The equipment should be installed by an audio visual technician observing 'good electrical and audio practice' at all times and following all the instructions within this document Only use the power adapter supplied with the
