The Shure BLX24/SM58 SM Wireless Vocal System offers the industry-standard, highly versatile SM58 cardioid dynamic vocal microphone, tailored to deliver warm and clear vocal reproduction in a simple to use wireless setup.


The BLX2 transmitter is fitted with an industry standard SM58 capsule which is tailored for vocals with a brightened midrange and bass rolloff. The cardioid polar pattern picks up the most sound from in front of the microphone and some sound from the sides making it less susceptible to feedback in high volume settings.

The BLX2 transmitter features adjustable gain control, power and battery status LED, quick frequency matching and up to 14 hours of continuous use.

The BLX24/PG58 system comes with the Analogue Wireless Receiver BLX4 which provides improved linearity and frequency response. The BLX4 receiver is ready to perform right out of the box and is the clearest choice for performers who wish to unplug from the wire.

Setup is simple, with one button starting the group and channel scan to find the best open frequency. Just adjust the transmitter to the same channel and you're ready to go. There's up to 12 compatible channels available.

For ideal signal strength, antennas on a wireless system need to be set up in a certain way. The internal antennas on the BLX4 receiver are already set in this ideal way, offering up to 100 m operating range and optimal signal strength.
