CLD1 small area and counter loop driver

CLD1 small area and counter loop

Part code: CLD1 (see below for kits)

The CLD1 small area and counter loop driver is designed for counter systems and small area perimeter loop systems. Measuring only 128 x 74 x 35mm and with an output current of 2.4A RMS, the CLD1 is the smallest and highest performance amplifier in its class.

Information

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

CLD1 small area and counter loop driver

The CLD1 small area and counter loop driver is designed for counter systems and small area perimeter loop systems. Measuring only 128 x 74 x 35mm and with an output current of 2.4A _RMS, the CLD1 is the smallest and highest performance amplifier in its 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.

CLD1 small area and counter loop applications include:

Ticket and service counters
Retail counters
Information kiosks
Reception desks
Interview rooms
Small meeting rooms
Taxis and private cars

Please also take a look at the TalkPerfect Dx Speech Transfer system for communication across barriers.

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.
