Product Description
The SR55 receiver makes true diversity wireless technology available to everyone. This "diversity" design houses two antennas and a receiver circuit in a single chassis. The advanced circuit design continuously scans RF signals from the two antennas and determines which one has the clearest and strongest reception, automatically (and silently) switching that signal to the receiver.
With the Stage 55 Wireless System you get incredible reception, crystal clear sound in a VHF system priced to bring the freedom of wireless to everyone. This system offers transmitters for every application, including handheld, headset and lavalier microphone styles. It's perfect for guitars too, just plug in with a Samson GC5 guitar cable.
