Speaker System Wiring Using the Line Out
Item Description
Speakers
Powered amplifier
Line out and subwoofer out
The subwoofer cable provides a single mono output to a powered
subwoofer or subwoofer amplifier. You may need to use an RCA
splitter to connect this to an amplifier.
Amplifier-on signal wire
A connected amplifier must use the same ground (-) as the stereo
for this signal wire to function correctly.

NOTE: You can connect speakers to the speaker wires for the
internal stereo amplifier while using the line out, although
adjusting the volume affects both the speakers connected to the
internal amplifier and the line out. This may result in uneven
volume levels.
Fusion PartyBus Networking
The Fusion PartyBus networking feature allows you to connect
multiple compatible stereos together on a network, using a
combination of wired or wireless connections.
You can group a compatible stereo, such as the Apollo RA770
stereo, with other compatible stereos connected to the network.
Grouped stereos can share available sources and control media
playback on all of the stereos in the group, which allows for a
synchronized audio experience across the vessel. You can
quickly create, edit, and break up groups as needed from any
compatible stereo or remote control on the network.
NOTE: A zone stereo, such as the SRX400, can create or join a
group to control and play sources from other stereos, but it
cannot share its sources with the group.
For additional considerations when sharing sources, see the
owner's manual.
You can use compatible stereos and remote controls, whether
they are grouped or not, to adjust the volume of the available
speaker zones for any stereo on the network.
You can connect up to eight Fusion PartyBus stereos on a
network wirelessly.
Wired Networking Considerations
When you are planning your network installation, observe the
following considerations for all wired connections.
• You must connect devices using standard Cat5e or Cat6
network cables with RJ45 connectors.
• You can use one network cable to directly connect two
compatible devices.
• You must use wired network switches and wired or wireless
network routers when you connect more than two compatible
devices to a network.
• If you install a router on the network, it should be configured
to be a DHCP server by default. See your router instructions
for more information.
• If you do not install a router, and there are no other DHCP
servers on the network, you should configure one Fusion
PartyBus stereo to be a DHCP server (Setting the Fusion
PartyBus Device as the DHCP Server, page 5).
Wired Network Example for Direct Connections
No network setting changes are needed when connecting two
devices together directly, but for the best results, you should
configure one device to be a DHCP server (Setting the Fusion
PartyBus Device as the DHCP Server, page 5).

Wired Network Example with a Switch or Router
You must use wired network switches, a wired network router, or
both to connect more than two devices.
If you did not install a router, and there are no other DHCP
servers on the network, you should configure one Fusion
PartyBus stereo to be a DHCP server (Setting the Fusion
PartyBus Device as the DHCP Server, page 5). If you
installed a router, you may need to configure it to be a DHCP
server. See your router instructions for more information.

Wireless Networking Considerations
When you are planning your network, observe the following
considerations for all wireless connections.
• Wired connections are more reliable than wireless
connections. You should plan your network to use network
cables, but if it is not possible, many Fusion PartyBus
