5.1 or 7.1 Multichannel Pre Amp or maybe AVR

It is pretty cool! Saved my bacon for a really niche use case. Each 3.5mm out is 2 channels: Front L/R; Rear L/R; Rear Surround L/R; and Center/Sub. So one 3.5mm per 2 channels --> 1 RCA per channel.

The niche use I might have for this device is for driving an old (pre-DD+) AVR from a Roku via optical. I’m using an old 4640 Roku Ultra, which is the last Roku model that does transcoding of DD+ to DD optical. The 4640 is working for now, but if it ever gets obsoleted, I think I can use your device to get a DD optical feed from a new Roku.

I don’t know if it helps the OP, but this is a cool device.
 
Thanks for the heads up on accessories4less...

I am not going to buy this stuff until I have the space ready. Next week will be a big one trying to get this completed. It's a Barndo baby!

Hey I almost forgot! I have this guy that's taking up space. It's yours for the cost of shipping if you want it. It does have some limitations: it won't pass through modern video so you'd need an HDMI splitter -- they're pretty cheap. It decodes "all the usual Dolby Digital and DTS modes, the Pioneer features onboard decoding of both Dolby TrueHD and DTS-HD Master Audio lossless." No Atmos though, but since it seems like you're doing 5.1 that's not a big deal.

Dude. That is a kind offer that I may take you up on. Maybe I have some piece that might fit one of your projects.. So much packed away.

Many thanks.

Looking at the current projectors... The Epson laser 3 chip projectors appear to have high lumens rating in both white and color. The display options seem to be either WUXGA or 1080p. I don't see the 4K and 8K in these models until you get into the $15K professional stuff. I presume that WUXGA is not going to work with my Roku or BluRay. Go with the 1080p. Which is fine for a garage. I want brightness on a 200 in screen +/- with a throw of 32 ft.
 
The screen will be painted. Mostly white with a bit of silver. Some reflective glass or metallics. I want high gain.

In the past I used two layers of Spandex, white over silver for an acoustically transparent screen. Spandex could go to about 120 diagonal on a frame that you build. Having LRC behind the screen was a huge difference.

At a quick glance, there look like there are plenty of inexpensive 4k Epson projectors. I don’t know which models are best but the Epson Home Cinema 3200 4k, for example, is 2900 lumens for around $1500.

For the screen, it’s best to use projector central or some calculator to determine how reflective to go (I think there is something like that, but I might be wrong). I know that if you go too reflective on a bright projector, it can sparkle, but then you have a very long throw and large screen, so I don’t know how that would affect screen choice.

When I got a replacement screen, I got several samples and the more reflective ones sparkled. You may know much more about this than me though.
 
All experience is good experience. That is how we learn. The big deal is that this space is 32 ft across from the projector to the screen (wall). 17.5 ft high. Most HT theater projectors (not short throw) put up 120 or so at 16 feet. That won't work. I am projecting from the back of a large space. Like a conference room. The ceiling is too high to use as a mount. Looking for an alternative to Epson. Not really finding it.

An Epson Pro EX11000 has the correct throw and can hit 200 inches at 32 ft. 4600 lum both color and white. ???. Suitable for 300 inch screen in proper conditions. 1300 bucks? I am limited to 1080p. I think that is great as long as it is bright. I'll screw with the paint mixture. That I can do.

Can you not hang the projector from a midpoint in the room to reduce the throw length?

The bigger the screen, the more you’ll benefit from 4k. Even 1080p looks better on 4k from upscaling.

I had a “Darbee” device on my prior 1080p, which is a somewhat obscure video processing device that make 1080p look better - when you run Darbee on half the screen it’s pretty shocking how much it helps the picture versus the unprocessed side - but 1080p still looks better on the 4k versus prior 1080p with Darbee.
 
Since you have so much overhead space, have you thought about an Atmos-capable AVR?

Frankly, in this day and age, I don't even know if they make AVRs without Atmos.

Maybe at the cheap end.

Make yourself a 5.1.2 or even a 7.2.4 (where the last digit is the number of height, or ceiling, speakers).

I run my system through an aging Pioneer Elite AVR, and I'd never heard a good Atmos system until I took my copy of A24's production of Talking Heads' Stop Making Sense.

That was over a year ago, and I'm still impressed by it.
 
The ceiling is almost 18 ft. That is a big dangle.

How high will the top of the screen be (including whatever vertical space under the screen you keep open)? I think (not certain) that the vertical lens shift on most Epson projectors allow you to position the projector at the top of the screen, or near the top.
