All sets also come with rechargeable accupacks with up
to 15 hrs of operating time. The accupack is also USB
rechargeable, the cable is in the box, the USB socket is
presumably just a step away from you.
The two types of sets are either Rackmount Sets (-R version), which come with everything needed for rack mounting, or Case Sets (-C version), in a transport case – without
rackmounts, if you do not want to install the receiver.
