  • 1Description

The Alto Professional Radius 200 Professional UHF Diversity Wireless Microphone System operates over the 520 to 937.5 MHz frequency spectrum. It features True Diversity design that utilizes two separate receiver sections as well as two antenna systems. The unit constantly polls both receivers and the signals at the antennas to instantly and seamlessly select the stronger signal. 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.
