Shure BLX2/SM58 Wireless Transmitter

This transmitter is designed to work specifically with Shure BLX4, BLX4R, and BLX88 wireless receivers. It will not function with other Shure wireless systems or receivers from other brands.

You can expect up to 14 hours of continuous use on a fresh pair of AA alkaline batteries. This makes it a reliable choice for long gigs or all-day events without needing a battery swap.

Yes, the BLX2/SM58-H9 uses the same industry-standard SM58 microphone capsule found in the wired version. You get the same warm, clear sound profile and rugged durability, just without the cable.

The transmitter offers a line-of-sight range of up to 300 feet. In real-world environments with walls, crowds, or other electronic interference, that range may decrease, so it is best to maintain a clear path between the transmitter and receiver whenever possible.

The BLX2 transmitter features a -10 dB gain attenuation setting. You can adjust this directly on the transmitter to prevent signal clipping if you are working with particularly loud sound sources.

The transmitter is built with a molded ABS housing, making it lightweight yet rugged enough to handle the rigors of regular stage use. While it is durable, it is still a piece of precision audio equipment, so it should be handled with standard care.
