I hear a delay when using the external input with my TV

If you are connecting the External input with your cable or satellite box for enjoying TV audio through multiple HEOS 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 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.
