The Alto Professional Radius 100 Professional UHF Diversity Wireless Microphone System operates over the 520 to 937.5 MHz frequency spectrum and features a dual antenna UHF diversity receiver. If one antenna experiences signal interruption, the receiver instantly switches to the second antenna. This assures you of a stable, reliable wireless signal, with virtually no chance of dropout or interruption.

A single-button can be pressed to scan for the optimal transmission frequency, and the connection between transmitter and receiver can be easily synchronized. Squelch control helps minimize background noise during silent periods, and a front-panel rotary volume control provides precise control over the output level. This wireless microphone system includes a headset microphone and wireless belt-pack transmitter.
