Our take on the Shure BLX4

by Bob Bihlmayer
Shure

Receiver for BLX systems

Shure's BLX4 wireless transmitter is part of the BLX family of digital wireless systems. The BLX4 is a single-channel wireless receiver which features simple frequency matching with Shure's BLX line of transmitters. Its XLR and 1/4" outputs allow use with a variety of systems. Whether you're miking a vocalist or an instrument, the BLX4 is ready to receive.

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.
