About HEOS
The HEOS system is a true multi-room audio system that automatically synchronizes audio playback between multiple HEOS Built-in devices so that the
audio coming from different rooms is perfectly in sync and always sounds amazing! You can easily add up to 32 HEOS Built-in devices to your HEOS
system.

What is a HEOS account?
A HEOS account is a master account or “keychain” for managing all of your HEOS music services with one single username and password.
o
Why do I need a HEOS account?
With a HEOS account, you only need to enter your music services login names and passwords once. This allows you to easily and quickly use multiple
controller apps on different devices. You just log into your HEOS account on any device and you will have access to all of your associated music
services, play history and custom playlists, even if you are at a friend’s house listening to music on their HEOS system.
o

I hear a delay when using the external input with my TV
I hear a delay when using the external input with my TV.
0
If you are connecting the external input with your cable or satellite box for enjoying TV audio through multiple HEOS built-in devices, you may hear a
delay between when you see someone speak and when you hear the audio. This is because the HEOS system must buffer the audio before it sends it
out to the HEOS built-in devices, so that it arrives at all devices at the same time. You can avoid this delay by listening only to the device which is
directly connected to the set top box.
Resetting network settings
0
