This Shure PGX4 Wireless Microphone System includes either the legendary Shure PGX2/SM58® or the PGX2/Beta58A, and the PGX4 receiver!

Packaged with the PGX4 receiver and the PGX2 transmitter, the SM58® has been the #1 choice of performers and worship leaders. The receiver makes wireless setup a snap including features like Automatic Frequency Selection and Automatic Transmitter Setup, the PGX4 offers the best in wireless to performers on the go.

The PGX2 transmitter is designed to meet the needs of traveling performers, featuring your choice of two of the industry's most reputable and best-performing microphones: the legendary SM58 and the precision-crafted Beta 58A®. The transmitter design allows for interchangeable microphone cartridges.

The Shure Beta 58A® is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide.

The Beta 58A maintains a true supercardioid pattern throughout its frequency range. This insures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille.
