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

• A zone stereo, such as the Apollo™ SRX400, 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).

• You can disable sharing on most sources by changing the GROUP ENABLED setting for the source. When disabled, the source cannot be selected from a grouped stereo (General Settings).

• 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 (General Settings).
