I used this device to receive an HDMI signal from an AppleTV and send the audio to an audio matrix (amplifier), the speakers as a whole house supplied with electricity. It works exactly as I had hoped. The device takes a single HMDI input (an AppleTV in my case), routes the entire signal (audio and video) to an HDMI output (to my TV) and then also sends the audio signal out the RCA jacks (red/white ). . which I then connect to my audio matrix (amplifier). This unit is perfect if you have an old A/V receiver that doesn't have HDMI inputs, or, in my case, an entire home audio matrix (HTD Direct brand) that only accepts RCA inputs. I have three of these devices (one for each AppleTV). I only give 5 stars to products that I consider "absolutely perfect". This product could be better if it had a way to mount the device with a bracket or something. I keep three of these in my AV closet and because they are small and light they tend to get dragged around with attached cables - it's difficult to keep my AV closet clean and tidy. But 5 stars for the technical function.
