World's Smallest x2
The QT-256® Dual is two completely independent QT-256® audio transmitters, each with it's own battery and internal antenna, packed into an unobtrusive aluminum housing roughly the size of a deck of cards.
Complete Redundancy
Tune each transmitter to a different frequency to broadcast on two separate channels, if there is any sign of interference on one channel, you've got a fallback.
Peace of Mind
The Dual was developed for high profile live events. It is used by referees in the Superbowl and conference speakers like Bill Gates.
