The Glensound GS-FW021 is a very small and useful headset interface to 4 wire circuits. It is ideal for talkback and intercom in studios, theatres or outside broadcast environments.

As well as providing a traditional 4 wire interface it also has a loop through interrupt mode (IFB) and a 2 wire conference mode.

It has a very long battery life (in excess of 100 hours). Three user selectable modes make it versatile for a number of uses and compatible with many other manufacturers’ products.
