I'd be delighted to help you optimize your setup. I just love efficiency.
If you would please give me the model numbers of your receiver and televisions as well as a list of everything you want to hook up, I can give you some solutions.
Wow, outstanding. Well, first, I do have a weird issue with my Onkyo TX-SR606 in that it does not smoothly switch between the audio. As in, I press, say, the "Game" button to switch to the stuff plugged into the "Game" port, but it will not switch unless I head into some menus. It's possible maybe, that, given all the splitters and stuff hooked up, it just takes the signal a while to go through, and my messing around just takes up time. This might actually be one of the most cobbled-together set-ups you'll ever imagine.
There are three splitters, two standard def, and AV, one HD. I have my three HD consoles hooked up with component cables rather than HDMI (so the picture isn't quite as sharp), and they are in the other HD splitter. The Onkyo has, I think, 5 HDMI inputs, but I'm not using them, because the Onkyo outputs to a DVD Home Theater system, and all the audio goes through there. So, all audio and video into the Onkyo, then all audio out from there to the DVD Home Theater, and all video out to the TV in one of three (might be two) channels.
My Onkyo receiver has no speakers of it's own, and was purchased used from a Pawn Shop. I've often wondered if it may be faulty.
What I've most wanted was a way to reduce the number of switches to reduce clutter, possible signal interference, and to make switching between things faster and easier. Ideally, I'd love if everything could go through the receiver, but it just doesn't have enough ports.
At one point, I was annoyed by the lack of ports on these things, then realized that, "oh right, most people aren't trying to cram 40 game consoles into this at once." I'm wondering if I can do HDMI into the receiver, then audio out to the DVD home theater, and remove one set of switches entirely. I actually have no shortage of HDMI cables. I worked seasonally at Best Buy one year and made sure to load up on HDMI cables while I could still get 'em for $3.
I would
also (and I may be getting greedy at this point) love it if I could get my far older systems to run on the HD. The 2600, 5200, Master System, TG-16, etc. Weirdly, the the Jaguar is also hooked up in this way, but those are all on a CRT television next to the whole thing.
Currently wired through my beastly set-up:
SNES, Genesis, Xbox 1 (the original one), X360, Dreamcast, 3DO, GameCube, N64, PS3 (the PS2 gets unplugged when the PS3 is used, so it's just sitting there, not plugged in at all), PS1, Wii U. Offhand, I'm not even sure where the Saturn is hooked up. I have no plans to remove the old CRT entirely because, well, what if I want to play old light-gun games? I need that TV, then!
Going to the CRT:
NES, TG-16, 2600, 5200, 7800, Jaguar, Master System, possibly the Saturn. I'd like the option to put these on the plasma TV, but only have RF switches for them, which--especially for the older ones--does not appear to work. It was like the TV didn't know what to do with so few pixels the time I plugged the 2600 into it.
There is also a Neo-Geo X here, but that
only has an HDMI cable.
There is also the aforementioned DVD Home Theater system (a Magnavox, 5-disc changer, which may be ready for retirement), a VCR not currently plugged in, and an Aiwa record player. Yes, a record player. With the vinyl Bioshock soundtrack sitting on it. I am potentially getting a PS4 later this year, and will need to accommodate that as well.
There's the mouthful. After being shown the JVC JX-S700 up top with the first response, I'm looking into possibly getting that, or a bigger one if they make a bigger one.
