ARRIS DCX3501 Quick Start Guide - Manual (Page 7)

Note : If the A/V receiver
includes an HDMI input and
output, the DCX set-top HDMI
output can be connected directly
to the A/V receiver’s input and
the A/V receiver’s HDMI output
directly to the TV. Because HDMI
provides both video and audio
output, no additional audio
connections to the A/V Receiver
and TV are required.
