Ampetronic CLD1AC-CB compact induction loop kit with integral power supply and boundary microphone

General Description

The Ampetronic CLD1AC compact induction loop amplifier is designed for counter systems and small area perimeter loop systems. Measuring only 180 x 75 x 35mm and with an output current of 2.4A rms, the CLD1AC 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 CLD1AC 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 CLD1AC 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
