General

If you are a sports instructor looking to save your voice, Shure's BLX14RE/SM31 set gives you a complete and easy way to amplify your voice. The set consists of a BLX1 beltpack transmitter, the BLX4 receiver and an SM31FH headset microphone. The BLX1 bodypack weighs just 75 grams and runs for about 14 hours on 2 AA batteries. The BLX4 receiver has two built-in antennas that are always properly tuned. If you move around a lot, it is obviously important that the microphone can take a beating and stays in place. The SM31FH is specially designed for sports use. So this condenser microphone is extra light and it is moisture-resistant. Finally, this set comes with all the rackmount accessories you need to mount the receiver in a 19-inch rack!
