Hello. To group your HEOS speakers with the AVR-S730H, you will first need the HEOS App, and to have the speakers connected to your network. In the HEOS app, first select the AVR-S730H and then pinch the rooms together to create a group. You can also group the rooms by pressing and holding on one of the speakers, and dragging it into the group.
If the intent is to group your HEOS 1 speakers for TV playback, you will need to first enable TV Sound Grouping in the HEOS App under Settings > My Devices > AVR-S730H > TV Sound Grouping.
If the audio being played is a surround format, it will downmix to stereo for playback on the grouped HEOS speakers. The HEOS speakers cannot be used as discrete surround channels.
