MAXIMUM AMOUNT OF HEOS SPEAKERS

How many HEOS speakers can be used at one time?
You can use up to 32 HEOS systems simultaneously with a maximum of 8 systems in each Group*. The HEOS App is also flexible enough where you can create up to 16 Groups. (2 systems per Group)
*Group refers to the HEOS App's ability to take multiple HEOS systems and play them together so you're outputting the same source information from of all of the HEOS systems at the same time. Grouping the systems will also allow for proper synchronization to all systems so you should never hear an audio delay between the HEOS systems.
To Group systems simply use your device's touchscreen to drag and drop one HEOS system (room) into another.
