Ampetronic CLD1-AC Counter Hearing Loop The Ampetronic CLD1-AC Counter Hearing Loop is a Small Area and Counter Loop Driver designed for the same applications and to the same specifications as the CLD1, however the CLD1AC is fitted with an internal power supply for standalone applications.The CLD1-AC Compact Loop Driver is designed for counter systems and small area perimeter loop systems. Measuring only 180 x 74 x 35mm and with an output current of 2.4A RMS, the CLD1AC is the smallest and highest performance amplifier in it’s class. Designed and built to Ampetronic’s high standards of reliability, backed with a 5 year warranty and Ampetronic support, the CLD1 offers certainty of performance and the lowest lifetime cost available.Audio quality is ensured with metal loss correction (MLC) combined with Ampetronic’s usual high standards of design. The CLD1 is designed for flexibility and convenience, featuring 2 separate microphone inputs with independent level controls, one of which can be configured as a line input.All cable connections are made on a single face of the unit, adding flexibility and further simplifying installation. Ampetronic CLD1-AC Counter Hearing Loop Applications Include: Ideal for retail counters, reception desks, ticket booths, and small meeting spaces, the CLD1-AC is a reliable and cost-effective solution for hearing accessibility needs.For added convenience, the CLD1-AC variant features an integral power supply, eliminating the need for an external adapter.Ticket and service countersRetail countersInformation kiosksReception desksInterview roomsSmall meeting roomsTaxis and private cars For availability, pricing, and installation inquiries, please contact us today!

The loop should be mounted vertically in accordance with the installation instructions. Other installation methods are also available.The CLD1AC in this application will project a field to the requirements of IEC60118-4 approximately 1m from the preformed loop.Perimeter Loops – Area Coverage (maximum)The CLD1AC is designed for small perimeter loop applications in rooms or in vehicles. Coverage with a single turn loop:Room aspect ratio: 1:1 2:1 3:1Maximum area coverage m2: 20 30 35The CLD1 is DC powered making it ideal for use in small vehicles such as taxis, private cars and small boats. We recommend a multi-turn loop in the headlining of the vehicle cabin – contact Ampetronic for an application guide.The loop is 1-2m above or below the receiver heightThere are no metal structures in the plane of the loopThere is sufficient voltage to drive the cable length – check table below.Maximum Cable LengthWith maximum current output the CLD1AC can drive:Loops with DC resistance from 0.3 to 1.0ΩImpedance up to a maximum of 1.3ΩWhen operating below maximum output, the CLD1AC can drive longer cable lengths – contact Ampetronic for more details.Maximum cable length is dependent on cable type and on the application.Cable typeMaximum Cable Length (m)0.75mm2 copper441.0mm2 copper571.5mm2 copper711.8mm2 flat coppertape 101m CLD1 SpecificationsINPUTSPowerAll integral 100-240v AC 18W max.Regional plug also available.Green LED Power indicatorInput 1Microphone inputSuitable for unbalanced electret microphone3.5mm mono jack socketInput impedance 8kΩ.6v bias via 10kΩ sourceSensitivity -60 dBu for max outputOverload level -14 dBu.Recessed control on front panelInput 2Switchable line / microphoneRecessed switch on connector panelMicrophone as for input 1Line input:Input impedance 820kΩSensitivity -20dBu for max outputOverload: > 20dBuOUTPUTSDrive voltage>3.2Vrms >4.5Vpk at maximum output currentDrive current2.4Arms 3.4Apk continuous 1kHz sine waveShort term peak >4.8ApkLED indicator on front panelLoop resistance0.3Ω to 1.0Ω resistive orLoop connectorVibration proof clamps, accept 0.5 to 1.3mm2THERMAL HEAT CHART Idle1/6 peak Output Current (Speech)1/3 peak Output Current (Pink noise)Full PowerDriver ChannelsCurrent (ARMS)Load Resistance (Ohms)AC In (W)BTUAC In (W)BTUAC In (W)BTUAC In (W)BTUCLD112.40.50.6241382213.70437AUDIO SYSTEMFrequency response80Hz to 6.3kHz ±1.5dBAutomatic gain controlAGC optimised for speechDynamic range >36dBGreen LED indicator on front panelMetal loss correction0 to 4.5dB/octaveRecessed control on front panelPHYSICALCoolingNatural convectionDimensions180mm, 74mm, 35mmWeight400gEnvironmentIP20 : 20 to 90% relative humidity, -20ºC to 50ºCMountingHorizontal or vertical panel or wall mount, with 2 screw fixings Downloads: UP16501 CLD1AC handbook UP35701 CLD1Datasheet UP30113 All about counter induction loops UP15703 Quick start guide
