Yamaha HTR-3064 review
1080p HDMI with 3D and Audio Return Channel (4 In/ 1 Out) deliver crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI can provide an interface between most audio/video sources, such as a set-top box, Blu-ray player, DVD player, or A/V receiver and a video monitor, such as a High Definition Television (HDTV), over a single cable.
Audio Return Channel (ARC) is a distinctive 3D-ready function allows consumers to use a single HDMI connection to transfer digital audio from the TV back to the AV Receiver eliminating the need for a second cable between the TV and the home theater AV Receiver.
