Compact Loop Driver
- Low lifetime cost
- 5 Year Warranty
- Desk microphone and pre-formed loop in counter kit
- 2 independent inputs featuring 1 mic input and 1 switchable mic/line input
- Metal loss compensation
- All connections to a single face for installation convenience
- 12V DC or external AC power pack supplied as standard
The CLD1 Compact 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 it’s class. Designed and built to Protec’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 (MLC) combined with Protec’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.
- Ticket and service counters
- Retail counters
- Information kiosks
- Reception desks
- Interview rooms
- Small meeting rooms
When supplied as a counter loop kit, the CLD1 comes with a desk 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.
