I can't wait to enjoy the JVC. After Epson 8700 it will be a nice upgrade.

I talked myself right out of that sale didn't I? I am sure, you will enjoy Mark's projector.

Measured fan noise in high mode with everything else off and Radioshack SPL meter positioned near fan exhaust port - averaging 63 decibels.
Anyone else taken a db measurement of their RS45 fan noise running in high lamp mode? I want to make sure mine is indeed running louder than normal before going through the effort of packing in up and sending it in for warranty work.

judging from the aspect ratio and screen size, I am guessing that you are using a Seymour AV Center Stage screen. Lighting up a 150" wide screen that has 0.98 gain is tough to do at this price point, especially if using best image mode.

Ideally in an anechoic chamber but that's asking a bit much. I did this at 1 meter and got 36db average in high mode. The rooms is 29db ambient noise (not a dedicated space).

Thanks again for taking the measurements. With you getting a reading of 67 db, that tells me my fan noise is probably normal running in high mode. I think my issue is my room is dedicated and very quiet...A/C has large diffusers and is so quiet I can't tell when it's on...A/V equipment is in a separate room. Other than the speakers, the projector is the only thing in the room that makes noise. Might be time to consider building a hush box.

It's a SMX Procurv, but same gain of .98 with the 2K AT screen material. Brightness is good at the moment since I just moved to the high lamp mode and added a Prismasonic lens. Definitely gives the projector a workout...don't expect my bulb to last beyond 500 hours.

I thought that the Seymour XD screen was 1.2 gain as advertised on their site? Or is that the gain of the material "strands" and once they are put into a weave, they lose .22 gain?

Hi folks,

Been lurking here for quite a bit while figuring and measuring and trying to get the "finance department" (aka wife) to approve... I am about to pull the trigger on a B-stock RS45 after talking to a very helpful Mike Garrett.. But I am noticing a bunch of folks here lately talking of selling theirs and jumping to different models.. is there something I do not know?

Just to give a little background.. I will be throwing from about 16' to a 109" (diag) Seymour XD AT Screen.
I will primarily be watching 2D HD / DVD / BluRay sources along with my HTPC Mac running XBMC via HDMI.

Only 3D very occasionally.. and only for me... the wife can't stand it... makes her sick. I know I will have to buy a emitter and glasses separate.
The room is fairly light controlled... 2 windows but I will have light blocking drapes on them to keep that pesky sun out.

This is my first projector and am quite excited at the prospect of the new theater room I am building. But also kind of daunted at the sheer number of options and possibilities in regards to equipment. Including the intricate calibration and setup required.


I guess my question is... would I be better served to get on the waiting list for the new 46 or will the 45 suit my needs.
Are you guys really happy with the performance over time? I know it is all new and shiny out of the box... but what about 1 or 2 years later?

Thanks for helping out a complete N00b..

Many of the 45 owners are talking about going to the new JVC RS4810. The 4810 has E-shift 2 (4K upconversion).

I was conflicted with my options of staying with my HD250, going to a 4810, considering a Panny AE8000. I ordered the AE8000 and then cancelled it because of fear of losing the JVC's blacks. Then I saw that AV Science had B stock RS45s. I ordered from Mike and I had mine in a week. I love it! Beautiful picture! 3D is totally acceptable. I do see occasional ghosting and the occasional thin pencil outlines of images. It's not ideal. It will definitely get me 1-2 years of enjoyable 3D and fantastic 2D viewing. I am using Xpand 104s because they have the option to upgrade to RF in the future- given a lot of projectors are heading that way.

Yikes... those are a little too rich for my blood. I guess I am not a cinephile and tend not to notice the finer details / imperfections that a lot of others that post here in AVS notice. While I want my theater to be the best that it can be... (for the budget level that I am restricted to) I guess that 4K is not that important to me right now. While the new bulbs in the RS46 offer a bit of reassurance on durability and even wear over the hours of use... I think that my uncalibrated eye will be just fine with the 45.


Other 45 owners... in normal mode, what is the heat output of this PJ? I am thinking of enclosing it in a soffit ( with ventilation of course!) but was wondering how much I needed to provide for it as far as input cooling air and a output vent to get rid of the heat.

let me know your thoughts...

Thanks

Nothing at all wrong with the RS45. I use one myself. smile.gif

I am not a big fan of enclosing a projector. The more airflow around it the better the ventilation, the better performance. I find my JVC pushes a lot of heat out the vents so it would make me nervous putting it a box of any size. Just my opinion of course.
post #3942 of 4435
I've never had any issues in the past with a hush box. Just be sure to provide adequate ventilation. I had some fans rigged to a thermostat that turned on once the temp reached a certain point. It also had an alarm that would beep if the temp rose past a certain number.
post #3943 of 4435
As quiet as the JVC's and Sony projectors are, do you think that a hush box is needed? Not counting enclosing the projector so that it fits in with the decor better.

I was categorizing all projector enclosures as a "hush box" as that's what most people refer to them as. Kind of like a "jet ski". smile.gif

I'll rephrase and say I have had mine in an "enclosure" with no issues.

I'm so tempted to make a bad joke about hush boxes and wives/gf's, but I'll have to refrain.

Sorry, I was just trying to get the point across that many do not consider the need for a Hush box due to noise levels for Sony and JVC projectors. As I said many use them to make the projector fit the decor.

After owning a RS45 for nearly a year, I agree with Mike. This is one quiet projector, by far the quietest I've ever owned. I've owned projectors that demanded a hush box. The JVC RS45 is NOT one of them. In fact, when the projector arrived at my dealer, I asked them to fire it up and make certain everything was A-OK. He commended to me that when he turned it on for the first time, he was concerned that it was DO-A. Then the image appeared. It was so quiet that a ISF/CEDIA certified dealer was fooled!

Well... The trigger has been pulled... and the B-stock RS45 is soon to be winging its way to me.

The Soffitt is really my only way to make the PJ kind of blend into the room, I have kind of a lower celing so I want to sort of protect peoples heads from bumping into it ( and protect it as well ). It really isn't about the noise.. more about asthetics.

I look forward to getting to see what this puppy can do. Thanks all for your advice and thanks AV Science for the great deal!

Not sure if this works for you but consider a PJ elevator, this is how mine looks like.
post #3952 of 4435
breadvan, how far down does the elevator box hang below the ceiling? It seems like it hangs down quite a distance into the room. Wouldn't the projector hanging from a stationary mount actually be less obtrusive? Not critisizing, just wondering what the reasoning was for it. I could see if the elevator went into the ceiling to make it a flush ceiling until the projector dropped down.

No problem, we all have to deal with our issues our own way sometimes.

The reason for this was simply WAF. My other half hated the idea of a white pole sticking out the ceiling in our then new apartment, and knowing if the PJ was to be as near the centre of the screen as possible to minimize lens shift, the mounting pole would have to be long and obtrusive and gets in the way of “normal” life with kids in the house (you know, balls and what not flying through the air?). That’s why, to me anyway, the only way it would work was to shorten the ‘pole’ and to make it somehow disappear, hence this elevator box was ‘conceived’. The original box for my Panny AE2000 was like this, the JVC one is a completely new.

You are right the most ideal thing to do is to hide this under a false ceiling but with a 9-ft tall ceiling apartment you probably don’t want to do that! The box is about 30 inches down from the ceiling, and the elevator comes down around 20 more inches or so.

Yeah essentially, it's just a custom-made box with an elevator inside, but thanks anyway.

Ahhhhh.... (lightbulb goes off).

I would have thought that WAF would have gone against this kind of thing, but now hearing that you have the projector come down about 20 inches I can see the technical aspect of it. For some reason it doesn *seem* to be down that far, but in real life I bet it does.

Hey, as you said, we all have our different limitations. I have a "headroom" limitation in my theater and with my RS45 mounted above my 2nd row riser, I needed it as close to the ceiling as possible. In my case though, I am not anywhere near the limits of my lens shift, but I am sure that there is still some compromise in the picture. I just didn't want people hitting their heads.

Thanks again for the clarification.
post #3958 of 4435
Nice... very nice indeed.... but with a scissor lift costing just about the same price as the PJ... I do not think the other half will sign off on that regardless of the "cool factor". I will keep researching it though.

Is there anybody getting light leakage from the lens of their projector? Whenever my projector starts up and the dila logo pops up I see like a bluish tinge around the logo(diamond shaped). It also happens on images with darker backgrounds. mostly in the center of the screen this occurs. I'm using a Da Lite HCHP screen. Is the light leakage normal or should I ask to have the projector replaced? Anybody with knowlegde on this matter would be greatly appreciated. Thanks.
post #3960 of 4435
Mikeo, have you got your RS45 set up such that you haven't got much lens shift applied? I noticed a similar effect with my HD350(RS10) and found that moving the projector higher, then applying some lens shift resolved the issue. I believe it is something to do with reflections in the lens and a small amount of shift helps reflect them away from the imaging chip so you don't see the halos (or ghosting as I called it at the time, pre popular 3D display availability).

I thought this might have been resolved on later models, but my forthcoming X35 will be mounted in the same spot so I'll still need a bit of shift, so hopefully won't see this issue.
