Our take on the Shure BLX2/SM58 by Crutchfield's Bob Bihlmayer
Transmitter for BLX systems
Shure's BLX2/SM58 microphone/transmitter is part of the BLX family of digital wireless systems. It combines the BLX2 wireless transmitter with Shure's SM58 microphone, featuring the performance of that legendary mic in a simple, easy-to-use wireless package. The BLX2 transmitter automatically links to Shure's BLX4, BLX4R, or BLX88 wireless receivers (not included) for seamless operation. The transmitter boasts an operating range of up to 300 feet and will run for 14 hours on a pair of AA batteries.
When considering a wireless system, you'll want to pick the frequency band with the least interference from local TV stations. Shure's Wireless Frequency Finder will show you the TV stations in your area, along with a list of recommended channels. Choose the frequency band that gives you the most open channels.

Wireless Transmitter & Mic (for BLX Systems): The Shure BLX2/SM58 wireless transmitter & mic is specifically designed for use with Shure's BLX wireless systems (receivers & bodypacks sold separately). The BLX2/SM58 wireless transmitter & mic has a wireless range up to 300'. Up to 12 BLX wireless systems can operate simultaneously.
Integrated SM58 Mic Capsule: The Shure BLX2/SM58 incorporates Shure's SM58 vocal microphone. This legendary vocal microphone is designed for professional vocal use in live performance, sound reinforcement, and studio recording. Its tailored vocal response for sound is a world standard for singing or speech. A highly effective, built-in spherical filter minimizes wind and breath "pop" noise. A unidirectional (cardioid) pickup pattern isolates the main sound source while minimizing unwanted background noise.
Frequency Bands: This model BLX2/SM58 wireless transmitter & mic works on the K12 (614-638MHz) frequency band. When purchasing separate wireless components, please match their frequency bands to ensure proper system operation. Different Shure BLX wireless systems operate on a variety of frequency bands, including:
- H8 (518-542MHz)
- J10 (584-608MHz)
- K12 (614-638MHz)
- M15 (662-686MHz)
Battery Powered: The Shure BLX2/SM58 wireless transmitter & mic operates off of two "AA" batteries that can last up to 14 hours.
Microphone Placement: Hold the wireless microphone within 12" from the sound source. For a warmer sound with increased bass presence, move the microphone closer. Do not cover the mic's grille with your hand.
