So I’ve just bought a Shure BLX4/SM58 but am stuck when it comes to setting up. And of course it does not work by itself and needs some sort of stereo or PA system to make the sound work, so what cheap option do u suggest for this and how to overall set it up. Any information would be greatly appreciated.
The channel-matching between mic and receiver is fully described in the printed manual. If you've lost yours, here's a download.
Yes, you'll need a PA system to run it through. Same as you would if you'd bought a mic with a cable. They come in all sizes! Maybe the venue you'll be performing in has one that they'll let you plug into. What sort of work are you thinking of doing?
