The Rocketboost Wireless sender/receiver works as both a Rocketboost
wireless sender and wireless receiver, so you can use it in either
configuration. In fact, you can even use it as a wireless sender and
wireless receiver simultaneously.
Rocketboost is expandable. Each Rocketboost wireless receiver can
select the audio from any wireless sender in your Rocketboost audio
network. You can set up your network to meet your specific needs. The
illustration shows an example Rocketboost network.
