Alto Radius 100 Wireless Microphone System Overview
Alto Radius 100 Wireless Microphone System Product Overview by GAK
The Alto Radius 100 system provides consistent and reliable performance, engineered with new diversity technology. The design of the Radius 100 receiver uses two separate antenna systems. If one antenna detects signal interference, the receiver instantly switches to the other antenna which guarantees that your signal will always remain seamless and uninterrupted.
The receiver constantly evaluates the incoming signals to each of the antennas, instantly determining which one is the stronger, selecting that stronger signal for consistent, drop-out free performance.
This version comes with a handheld condenser vocal microphone transmitter.
