Wireless microphones hold the promise of freedom from restrictive cables and the ability to closely connect with your audience—whether that audience is a throng of concert attendees, an all-important business group or a crucial phone caller in an urgent situation.  These are the times when rock-solid dependability matters above all else.

The Alto Professional Radius 200 wireless microphone system is the answer.

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.

The Radius 200 also comes in four versions, all of which feature our True Diversity system:

• 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, 1/4-inch instrument adapter cable and wireless belt-pack transmitter

The Radius 200 True Diversity System represents the very best wireless microphone performance available. When everything is on the line and there are no second chances, the Alto Professional Radius 200 True Diversity wireless microphone system comes through for you. Every time.
