Theres a remote that is called Due Cue or something like that. ( I need to look ) but it is a remote that uses rf, and is able to go far. Plus you can link multiple receivers as repeaters and connect them by XLR. It has 2 usb outs so it can connect to 2 different computers at the same time. It also has a selectable frequency so if you use multiple ones. if interested, I can find out who makes it. I do know it is expensive since it is made for professional use.
