I have an Oppo 103 and just picked up a new Panasonic Plasma so I want to make sure I don't have to much video processing in the chain.
Well one wire you can get rid of is the optical. HDMI from the sat box carries everything together, audio and video, to the AV7005. [At least that's how my cable box works] It, the AV7005, then splits off the sound (5.1, etc.) and sends it off to your amplifiers and speakers, while it simultaneously sends the image to the display.
If you set the pass through [or whatever they call it on this unit] to "Last" then the last thing you were using into the AV7005 (to listen to) passes through to the TV display via HDMI out. For example "Roku", or "DirecTv". Forget about using "ARC". It is better for people who use antenna, not sat boxes like you use, and remember to think of your Roku as just another source, just like your disc player, for example, or your sat box.
A system becomes markedly more complex when one insists: "Sometimes I like using the speakers in the TV, but at other times I prefer using the speakers connected to my amplifier."
This insistence often:
- adds confusion and ambiguity ("What WAS the last thing I (or an alternate housemate) had running through the AV7005? I can't remember or don't know what my spouse was watching while I wasn't here. DOH! Better power up the AV7005 just to check."
- adds wiring
- adds complexity of switching, having to make input selections some times on the AV7005, other times the TV, and sometimes both
- adds two different master volume controls so more remotes are on the table
How about instead:
- having only one input selection to make. [the one on the AV7005. The TV stays locked to one input forever on]
- never touching the TV or its remote to do anything, other than turning it on or off. [if it has HDMI-CEC you might even be able to eliminate that need]
- having a single wire running to the TV. [HDMI]
- having a single volume control (hence remote) for all situations
- minimize wiring by sending the source signals just to the AV7005, not also the TV
When you use a TV display in this manner it is best to refer to it as "monitor", because that's how you are using it.
"Any"? So if the last person using the AV7005 was watching a DVD, then turns the system off with the Harmony remote, but then person B comes into the room the next morning and selects "Roku using just the TV speakers" the Harmony will fire up the AV7005, select the Roku input, then power down the AV7005, allowing its "last passthrough" to be on the correct device? I find that hard to believe if it's using a typical, run of the mill, off the shelf programming.
