The PLD is a line-monitoring device for use with several Vocia amplifiers. It offers a simple and cost effective supervision method for many types of installed paging speakers, and can monitor up to a maximum length of 1.3km (4,300ft) of speaker cable.

The Vocia PLD-1 and PLD-2 are passive end of line devices for use with Vocia amplifiers (PLD-1: VA-8600; PLD-2: VA4300CV and VA-8150CV) on constant voltage systems. Each Vocia amplifier uses a pilot tone to ensure speaker line integrity between itself and the PLD. The device can be surface mounted.
