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 RA670 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.
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 should refer to the installation instructions provided with your remote control when constructing the Fusion PartyBus network.

Creating a Group

Before you can create a group, you must connect multiple compatible stereos to the Fusion PartyBus network. See the installation instructions provided with your stereo for information about installing and configuring the network.
NOTE: There are some limitations and other considerations when using stereos in groups. See Grouped Stereo Source Considerations, page 7for more information.

Select > GROUPS.
TIP: You can hold from any screen to open the GROUPS menu.
Select the name of the stereo you want to be the primary stereo in the group.
Select the stereos you want to add to the group.
Select DONE.
From the source screen, you can select a source from any stereo in the group except a zone stereo, such as the Apollo SRX400 stereo or any sources that are disabled for use on the Fusion PartyBus network.

Editing a Group

Select > GROUPS.
Select the name of an existing group.
Select the stereos you want to add to or remove from the group.
Select DONE.

Leaving a Group

You can leave the Fusion PartyBus group to play local sources on the stereo.

Select > GROUPS.
Select the name of the existing group you want to leave.
Select the stereos you want to remove from the group.
Select DONE.

Grouped Stereo Functions

After you create a group of stereos, additional functions and options are available to all stereos in the group.

After you create a group, all of the stereos in the group share the same synchronized display.
You can select a source from any stereo in the group, with a few limitations, and the source will play simultaneously on all stereos in the group.
You can control playback (such as pausing and skipping tracks) on any stereo in the group, and it will affect all stereos in the group.
You can adjust the volume for any zone on any stereo in the group.
TIP: When adjusting the volume, you can select ALL to adjust the volume of all the stereos in the group at the same time.

Grouped Stereo Source Considerations

When selecting sources to play over the network, you should observe these considerations.

You cannot share an AirPlay® source with grouped stereos. Using AirPlay 2 software, you can play content on multiple stereos on the network, but the stereos must not be grouped.
When audio sources are streamed over a data network, there is a slight delay in the synchronized audio that may be noticeable if you are also using an external audio source.
- If you have a television with an Optical Out connection to a stereo and you continue to use the television speakers, there will be a delay between the audio from the television speakers and the optical audio streamed on the grouped stereos.
- If you synchronize a radio station and tune that same radio station on a non-networked stereo, there will be a delay between the audio from the non-networked stereo and the audio from the radio station streamed on the grouped stereos.
- You can remove this delay by changing the GROUP ENABLED setting for the source, but the source cannot be shared with grouped stereos.
  NOTE: You cannot change the settings when a stereo is part of a group. You must remove the stereo from the group before you can change any settings.

Group Synchronization

By default, groups you create are not maintained when you turn off stereos in the group. If you turn off a single stereo added to the group, it leaves the group. If you turn off the primary stereo in the group, the group is dissolved. You can enable group synchronization to preserve group membership for a stereo after turning it off. Group synchronization behaves differently based on how you turn the stereos off and on.

If you turn a synchronized stereo off and on by using either the power button on the stereo or a physical switch on the ignition wire (the red wire), all of the synchronized stereos in the group turn off and on together. This applies to all of the synchronized stereos in the group, whether or not a stereo is the primary stereo in the group.
NOTE: Selecting ALL OFF from the power menu on a stereo turns off all stereos on the network, even if they are not in a group or have group synchronization enabled.
If you turn a synchronized stereo off and on using a physical switch on the power wire (the yellow wire), the other synchronized stereos in the group behave differently:
- If the synchronized stereo is the primary stereo in the group and you turn it off using a physical switch on the power wire, the other synchronized stereos in the group remain on, but leave the group. When you turn the primary stereo back on again, the other synchronized stereos rejoin the group.
- If the synchronized stereo is not the primary stereo in the group and you turn it off and on using a physical switch on the power wire, all of the other synchronized stereos in the group remain on and grouped, and the stereo rejoins the group when you turn it on again.

Enabling Group Synchronization

You must remove the stereo from an existing group before you can enable the GROUP SYNC setting. You cannot update settings when a stereo is part of a group.
You must enable this setting on each stereo that you want to retain group settings after a power cycle.

Select > SETTINGS.
Select the name of the stereo.
Select POWER OPTIONS > GROUP SYNC.
The stereo retains group settings after a power cycle.
Repeat for additional stereos as needed.
NOTE: You must enable GROUP SYNC on all networked stereos for synchronization to work properly.

General Settings

Select , select the name of the remote control, and select SETTINGS.
NOTE: If you select the name of the currently-controlled stereo before you select SETTINGS, you can adjust the settings of the stereo instead of the remote control.
When a stereo is in a group, you cannot change settings on that stereo.
The following setting descriptions apply to the remote control only. For information about stereo-specific settings, see the stereo owner’s manual.

Setting the Device as a DHCP Client

This device is set as a DHCP client by default. When set as a DHCP client, the device is configured for use on a network with a DHCP server. If no DHCP server is present on the network, the device assigns its own local IP address after a short delay.
NOTE: Although the Fusion PartyBus devices can communicate with each other without a DHCP server on the network, the devices take longer to connect to each other when you first turn them on. It is highly recommended to have one properly-configured DHCP server on the network for the best results.

Select > SETTINGS.
Select the name of this device.
Select NETWORK > DHCP CLIENT > SAVE.

Setting a Static IP Address

If the stereo is configured as a static IP, it is automatically assigned the IP address of 192.168.0.1. You can change this IP address.
If the stereo is a DHCP client on the network and you do not want the DHCP server to automatically assign an IP address to the stereo, you can set a static IP address.
NOTE: Every device on the network must have a unique IP address. If you select a static IP address that is the same as the IP address on the network, the devices will not work properly.

Select > SETTINGS.
Select the name of the remote control.
Select NETWORK > STATIC IP.
Select an option:
- To set the IP address, select IP, and enter the IP address.
- To set the subnet mask, select MASK, and enter the subnet mask.
  NOTE: The subnet mask must match all other devices on the network to work properly. A typical subnet mask is 255.255.255.0.
- To set the default gateway IP address, select GATEWAY, and enter the gateway IP address.
  NOTE: The default gateway is typically set as the IP address of the DHCP server on the network.
Select SAVE.
