ALTO RADIUS 200 UHF WIRELESS HEADSET MICROPHONE SYSTEM

The Radius 200 utilizes Alto Professional’s most sophisticated diversity system, a cutting-edge system called True Diversity. Alto’s True Diversity receiver design is absolutely state-of-the-art. True Diversity system improves upon Radius 100’s Diversity system because it utilizes two separate receiver sections as well as two antenna systems. The unit constantly polls both receivers and the signals at the antennae, to instantly and seamlessly select the stronger signal. This is what “bulletproof” wireless microphone performance sounds like.
