Forget the megaphone! This system is ideal for directors who don't wish to shout - comprises master console and three slave units.

This communication system was originally designed to help in the production of short commercial videos. With it, the “director” is able to hold a two-way conversation with any one of up to three camera operators. It is also possible to speak to all the operators simultaneously. No doubt, such a system could find many other uses, such as in amateur stage work, concerts and sports events etc.
