Radius 200 is an easy-to-use UHF True Diversity wireless microphone system that provides reliable, crystal-clear sound for the most demanding professional vocal applications. Alto’s True Diversity receiver design is absolutely state-of-the-art. Radius 200’s True Diversity system improves upon the Radius 100, 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.

Ready for any application, Radius 200 comes in four distinct versions:

  • Radius 200 – True Diversity receiver and hand-held condenser vocal microphone transmitter
  • Radius 200L – True Diversity receiver, lavaliere microphone and wireless belt-pack transmitter
  • Radius 200H – True Diversity receiver, headset microphone and wireless belt-pack transmitter
  • Radius 200M – True Diversity receiver, wireless belt-pack transmitter and 1/4-inch instrument adapter cable
