Hello Brett67, welcome to the community.
The CONNECT:AMP is only able to play one source of music at a time. If you're using 4 speakers and they are in different rooms, then all rooms will play the same music. However, you can install an impedance matching speaker selector switch to toggle one pair of the speakers off and leave just one pair playing.
To attach 4 speakers to a single CONNECT:AMP, the speaker impedance must be 8 ohms. Anything outside of that may damage the CONNECT:AMP and speakers.
