About this item

Shure quality

Tired of being tethered to a mic stand? Shure designed their BLX2/SM58 wireless microphone transmitter to set you free onstage. It marries the BLX2 wireless transmitter with the quality of Shure's SM58 microphone to capture your vocals with Shure quality. You'll get up to 14 hours of life from two AA batteries, so it's an economical mic to use.

Easy setup

The transmitter links to a BLX4 or BLX4R receiver (not included) for seamless operation. It's simple to set up the BLX2/SM58's transmitter and the BLX receiver. Press the Group button on one receiver channel and it scans for the clearest group and channel. Then just set the transmitter to the same group and channel settings. You can run up to 12 systems simultaneously depending on channel availability and RF environment.

SM58 capsule

The BLX2/SM58 features the legendary SM58 microphone capsule, which is known for its voice-tailored frequency response, rugged construction, and tight cardioid pattern which rejects off-axis noise. The SM58 capsule also has a pneumatic shock mount system and a grille of hardened steel to reduce handling noise and protect the mechanism.
