Alto Radius 100 Wireless Headset Microphone

The Alto Radius 100 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. The Alto Radius 100 owes it's incredible performance to new diversity technology. Alto's diversity receiver design utilises 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. This pack includes a headset microphone, wireless belt-pack and transmitter with integrated LCD display.
