CLD1AC

CLD1AC small area and counter loop driver

CLD1 small area and counter loop driver
Part code: CLD1AC (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.

The Ampetronic CLD1AC is 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.

CLD1AC small area and counter loop driver

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.

Applications include

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

Kit Forms

The CLD1AC 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 CLD1AC, 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).

Counter Loops

When supplied as a counter loop kit, the CLD1AC 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 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       3:1
Maximum area coverage m2:       20      30        35

  • 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.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.

Maximum Cable Length

With maximum current output the CLD1AC 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 CLD1AC 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
