I've got two SM98 wired mics, they have the thin mic cable that connects to the battery pack, the battery pack connects to the mixing board via standard XLR mic cable. I would like to convert them to wireless. I found an old post at the Shure support site that says "All Shure systems can be purchased without a microphone, so you do not need to purchase another mic with the wireless." (source) So ny quest is to find the right wireless system. The holy grail would be a two mic system since I play alto and tenor on gigs.
