Rocketfish designed this system to eliminate the need for running wires around your walls or under your floors (the latter is even more difficult if you do not have a basement). It comes with a sender unit (sending at 2.4 GHz), receiver unit, stand for the receiver unit, power adapter, and two 2-foot speaker wires. The setup is very simple. After connecting your surround cables to the sender unit from the amplifier, you will connect your surround speakers to the receiver. The cables that come with the system have terminals instead of wires, which is nice. It makes it extremely easy to connect. The only negative is that it doesn’t come with another set of cables, so you will still need to have some on-hand for your receiver unit.
