Fusion PartyBus Networking 9

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 (Grouped Stereo Source
Considerations, page10), and the source will play simultaneously on all stereos in the group (Selecting a
Source, page3).
• 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.
• Because this stereo is a zone stereo, it can create or join a group to control and play sources from other
stereos, but it cannot share its sources with the group.
• 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 (Apple AirPlay
®
, page8).
• You can disable sharing on most sources from other stereos on the network by changing the GROUP
ENABLED setting for the sources on those stereos. When disabled, the source cannot be selected from a
grouped stereo. See the owner's manual for your multi-zone Fusion Apollo stereo for instructions.
• 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.
10 Fusion PartyBus Networking

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