IL-PL21 External Boundary Microphone. Designed for placing directly onto the surface of a desk or counter.


The Contacta IL-PL21 small boundary microphone is ideal for use with the IL-PL20 portable loop system to provide an additional audio input source and is the microphone supplied with the RL-HLD3 Home Loop Kit.

It can pick up audio from all around thanks to its omni-directional pick-up pattern which means it's particularly useful for making sure the audio from several people gets fed into the loop system but can also be perfect for picking up the ambient noise in a room or the audio from a TV; it can also pick up the noise of a telephone ringing or a doorbell making it a handy addition to any domestic solution.

The microphone will provide its best performance when used on a flat surface such as a table or counter top.
