Ampetronic CLD1 Counter Hearing Loop
Ampetronic CLD1 Small Area & Counter Loop Driver
The 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.

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 counters
- Retail counters
- Information kiosks
- Reception desks
- Interview rooms
- Small meeting rooms
- Taxis 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.

Counter Loops
When 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 ratio | 1:1 | 2:1 | 3:1 |
| Maximum area coverage m2 | 20 | 30 | 35 |
- The loop is 1-2m above or below the receiver height
- There are no metal structures in the plane of the loop
- There 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 Length
With maximum current output the CLD1 can drive:
- Loops with DC resistance from 0.3 to 1.0Ω
- Impedance up to a maximum of 1.3Ω
When 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 type | Maximum Cable Length (m) |
| 0.75mm2 copper | 44 |
| 1.0mm2 copper | 57 |
| 1.5mm2 copper | 71 |
| 1.8mm2 flat copper | tape 101m |
