The CLD1 Compact Loop Driver is designed for counter systems and small area perimeter loop systems. Measuring only 5 x 2.9 x 1.4 in. (128 x 74 x 35 mm) and with an output current of 2.4 A (RMS), the CLD1 is the smallest and highest performance amplifier in its class. Based on proven and highly reliable technology it is backed by a 5 year warranty and Listen technical support. The CLD1 offers certainty of performance and the lowest lifetime cost available.
Audio quality is ensured with metal loss correction (MLC) combined with usual high standards of design. The CLD1 is designed for flexibility and convenience, featuring two (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.
