Adding more HEOS devices
The HEOS multi-room sound system is a true multi-room audio system that automatically synchronizes audio playback between multiple HEOS devices so that the audio coming from different rooms is perfectly in sync and always sounds amazing! You can easily add up to 32 devices to your HEOS system.
Each HEOS Drive contains four HEOS modules and therefore always counts as four devices towards the maximum number of 32 HEOS devices supported on any one network. Up to 8 HEOS Drive devices are supported on a single network.
