Digital Reference DR-R30 UHF Wireless

This setup has the extra body pack so you can use multiple instruments in the same set without having to change channels on your receiver. (Both packs cannot be on at the same time.) This system was used in a tour and was kept in a rack mounted flight case the whole time. It is in excellent working condition, and has very little wear. Here is some of the specifications from the manufacturers website.
