Fusion PartyBus Networking

The Fusion PartyBus™ networking feature allows you to connect multiple compatible stereos and zone stereos together on a network, using a combination of wired or wireless connections.

A Fusion PartyBus stereo, such as an Vieo™ RV 850 stereo, can stream sources to other Fusion PartyBus devices connected to the network. Connected Fusion PartyBus devices can also control media playback on the Fusion PartyBus stereo. A Fusion PartyBus zone stereo, such as an Apollo™ SRX400 zone stereo can stream from a Fusion PartyBus stereo, but cannot stream sources to other Fusion PartyBus devices on the network.

You can connect up to eight Fusion PartyBus devices on a network wirelessly.

In the image above, one Vieo RV 850 stereo 1 connects to a wireless router 2 and to two Apollo SRX400 zone stereos 3. The two Fusion PartyBus stereo zone stereos can stream sources from the Fusion PartyBus stereo.

A Fusion PartyBus zone stereo is not the same thing as a speaker zone. It is an independent stereo that can either play media from connected sources or stream from a Fusion PartyBus stereo on the network. You can connect a Fusion PartyBus zone stereo, such as an Apollo SRX400 zone stereo, to a single speaker zone 4. You can connect a Fusion PartyBus stereo, such as an Vieo RV 850 stereo, to multiple speaker zones 5 to cover a larger area with that stereo. Fusion PartyBus devices cannot control the speaker volume of another stereo. You can adjust the volume of speakers or speaker zones connected directly to the stereo only.
