Ampetronic CLD1 Counter Hearing Loop

Ampetronic CLD1 Counter Hearing Loop Ampetronic CLD1 Small Area & Counter Loop DriverThe Ampetronic CLD1 is a high-performance, compact induction loop driver designed for counter systems and small area perimeter loop installations. Measuring just 128 x 74 x 35mm, it delivers an impressive 2.4A RMS output, making it the smallest and most efficient amplifier in its class.Engineered to Ampetronic’s high standards of reliability, the CLD1 comes with a 5-year warranty and industry-leading support, ensuring long-term performance and the lowest lifetime cost.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.

Contact Us CLD1 small area and counter loop applications include: Ideal for retail counters, reception desks, ticket booths, and small meeting spaces, the CLD1 is a reliable and cost-effective solution for hearing accessibility needs.Ticket and service countersRetail countersInformation kiosksReception desksInterview roomsSmall meeting roomsTaxis and private cars Features: One of the smallest and highest-performing amplifiers in its class.Key features of the CLD1 include:Dual Independent Inputs: The amplifier offers two separate inputs with independent level controls. Input 1 is dedicated to unbalanced electret microphones, while Input 2 is switchable between microphone and unbalanced line-level signals, providing flexibility for various audio sources.Metal Loss Compensation (MLC): To counteract high-frequency losses due to metal structures in the environment, the CLD1 incorporates MLC, ensuring clear and intelligible audio reproduction.Compact and Robust Design: Built to Ampetronic’s high standards of reliability, the CLD1’s compact form factor allows for easy installation in limited spaces, such as under counters or on walls. All cable connections are conveniently located on a single face of the unit, simplifying setup and maintenance.Power Options: The amplifier operates on a 12V DC power supply and comes with an external AC power pack as standard. The CLD1-AC variant includes an integral power supply for added convenience.Warranty and Support: Ampetronic backs the CLD1 with a 5-year warranty, reflecting its commitment to quality and customer satisfaction.These features make the CLD1 a versatile and reliable choice for enhancing accessibility in various settings, including ticket counters, retail checkouts, information kiosks, reception desks, interview rooms, small meeting rooms, and even vehicles like taxis and private cars. Kit Forms The CLD1 compact loop driver can be ordered as a stand alone loop driver or as part of a kit for a specific application.Counter loop kits comprise 1 x CLD1, 1 x pre-formed loop, 1 x microphone (choice), 1 x loop present sign, 1 x installation guide and 1 x power supply (region specific). If required, the loop can be covered with a fabric pad to make it more aesthetically pleasing – see kit CLD001PD.  Kit CodeContentsCLD001Compact Loop Driver, A6 Loop Present Sign, Installation Guide, Region Specific Power SupplyCLD001CTCompact Loop Driver, Tie-Clip Mic, Pre-formed Loop, A6 Loop Present Sign, Installation Guide, Region Specific Power SupplyCLD001CDCompact Loop Driver, Desktop Mic, Pre-formed Loop, A6 Loop Present Sign, Installation Guide, Region Specific Power SupplyCLD001CBCompact Loop Driver, Boundary Mic, Pre-formed Loop, A6 Loop Present Sign, Installation Guide, Region Specific Power SupplyCLD001CXCompact Loop Driver, Pre-formed Loop, A6 Loop Present Sign, Installation Guide, Region Specific Power SupplyCLD001PDCLD1 Induction Loop Driver Multi PSU Desktop Mic Fabric Counter Loop PadCLD001XXCLD1 Induction Loop Driver Multi PSU, no Mic, no Loop Coil Information: Specifications Downloads: Information: Counter LoopsWhen supplied as a counter loop kit, the CLD1 comes with choice of microphone, a multi-turn preformed loop, power supply and simple installation instructions. The loop should be mounted vertically in accordance with the installation instructions. Other installation methods are also available.The CLD1 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 CLD1 is designed for small perimeter loop applications in rooms or in vehicles. Coverage with a single turn loop:Room aspect ratio1:12:13:1Maximum area coverage m2203035The 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.The 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.Maximum Cable LengthWith maximum current output the CLD1 can drive:Loops with DC resistance from 0.3 to 1.0ΩImpedance up to a maximum of 1.3ΩWhen operating below maximum output, the CLD1 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 Specifications INPUTSPower12V DC @ 1.0A max.Fuse fitted to PCB, type T 1.6A LGreen 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 1.3mm2 THERMAL 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 convectionDimensions128mm, 74mm, 35mmWeight280gEnvironmentIP20 : 20 to 90% relative humidity, -20ºC to 50ºCMountingHorizontal or vertical panel or wall mount, with 2 screw fixings Downloads:  UP35701 Datasheet-CLD1 All about hearing loops UP30113-4_All about counter induction loops UP15703-1 Quick start guide
