Not familiar with Pliant Technologies? We bet you are! They are the makers of the Tempest Wireless System which have been around for several years and provides wireless comm for many sports and events venues. They recently changed their name so that people could better recognize them in the entertainment industry. Their new product this year is Crewcom, which is a super capable network based wireless comm system. They like to think of it as intercom evolved! With its decentralized architecture, you can extend coverage to precisely where you need. The system is highly customizable and you can mix different frequencies in the same system. Best of all their beltpacks/headsets provide superior sound over older products. Consider this system the next time you are deploying a wireless comm system across a large venue.
