Alto RADIUS 100L UHF Wireless Microphone
Switching Diversity Receiver, Lavaliere Microphone and Wireless Belt-Pack Transmitter
This new wireless microphone system provides reliable, crystal-clear sound for a wide range of professional vocal applications, assuring users of an extremely stable, reliable wireless signal, with virtually no chance of dropout or interruption. This is the promise of wireless performance - delivered!
The key to its performance is its incredible new diversity technology. Alto's diversity receiver design utilizes two separate, antenna systems for uncompromised wireless performance. The receiver constantly evaluates the incoming signals to each antenna, and instantly determines which one is the stronger, selecting that stronger signal for consistent, drop-out free performance.
