The Ampetronic CLD1 compact induction loop amplifier is designed for ticket counters, banks or other point of sales systems. It can also be used for small area perimeter loop systems (up to 40 sq/m) 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, and backed with a 5 year warranty, the CLD1 offers certainty of performance and the lowest lifetime cost available

Audio quality is ensured with metal loss correction combined with Ampetronic’s usual high standards of design. The CLD1 is designed for flexibility and convenience, featuring 2 independent microphone inputs with independent level controls, one of which can be switched to a line input. All cable connections are made on a single face of the unit, adding flexibility and further simplifying installation

The CLD1 can be purchased with a microphone ready to be installed (please select above). The following microphones are available-

Lapel microphone

The small lapel tie clip style microphone can be worn by the member of staff or fitted to the counter structure. The microphone has an omni-directional pickup pattern and will be less effective at excluding background noise than the desktop or boundary microphones.

Desktop mic 

The desk microphone is a directional unit providing good sound pickup with reduced ambient noise and reverberation. It has a weighted base for stability when used free standing, alternatively it can be fixed to the edge of an upright panel using the rotational mounting coupling included.

Boundary microphone

The boundary microphone is small and unobtrusive ideal for concealment on a service counter. The design fixes easily to a desk top surface, and provided the desk can be drilled, the cable can be invisiblefrom the top. It has a directional, hypercardioid response which minimises room reverberation and background noise pickup, offering a clean, intelligible input signal.
