Most expensive units to be operating with impending doom for the pocketbook in a few years when that LCoS system in the light engine begins to have display issues due to the intense heat from the light gradually fades the arrays.
You need, at least 1000cfm exhaust with these units, or the bulbs will be black within half of their warranty period...and pull those SRX bulbs out (depending on what size you are using and if using 3D) when the taillight yellow and is blinking. If your exhaust isn't turned on after five minutes when the projector is on, the projector will shut down and lock up with an 'exhaust error' and the projector has to be turned off and shortly back on to remove this error message to get the projector back up and running again.
If you get a "Ballast Error", this could be a fatal message meaning either the bulb has died, or the ballast (rectifier) has failed. If the bulb has died, do a changeout and do the power cycle to clear this message.
If you're just leasing the units with a VPF deal, then it isn't so bad since it's not all of your money. But on a straight purchase, they're the "YUGO" of the D-cinema world.
They do give out a great 4K display with the correct content ingested.
Oh, the IMB inside is rather tempermental-they use "Deathstar" HD's in the RAID that one will fail on occasion.
Do a complete reboot once a week on these units so they can remain behaving if you're planning on keeping them on in standby mode at the end of the day.
I work with 10 of these creatures. Please PM me with more questions about these units.
But, doing your own installs is very complicated since there is a lot more installing digital than installing a 35 mm setup-you need Strong Technical Services to do your SONY installs for you.

Are you going to use your existing setup for sound or start from scratch with new processor amplifiers, speakers, et.al. ? Sonys can use the existing system but will need an interface device for the digital output from the IMB in the SONY to talk to the existing device processor. Ususally, the most common interface unit is the Ultra-Stereo eci60 interface unit that can be connected to practically any existing processor.
The "515's"
Good and (sorry) the bad:
Good - smaller footprint than the 320's and can do 4k resolution.
Bad-They use SIX UHP mercury bulb modules (three on each side of the console that must be installed) and if you know anything about mercury light, it's basically like the bulb is in a street lamp.
A bulb that, instead of using xenon gas, contains a drop of mercury that must be vaporized to emit light. Thus, there is a ballast that shoots a spark gap within the bulb to begin the vaporization of the mercury. Then the main arc takes over to emit the light. This is why when a street light ignites, it's very blue until the mercury is fully vaporized then will get to full brilliance. Making, you might have to leave the bulbs on at all times instead of shutting the bulbs off between performances since they take so long to be fully heated up to emit the best light possible.
The claim is that these UHP (Ultra High Pressure) mercury bulbs is that they have quite the duration, but will dim with age within a few hundred hours. And as with any bulb that dims with age esp with mercury bulbs, there will be an obvious color difference with the light. Xenon bulbs just get tired and lose their brilliance after a few thousand hours, but the color temperature will not change-it remains around 4100 degrees kelvin. Mercury bulbs lose their brilliance a lot sooner and the kelvin temperature will drop down to the 2700s which is a soft yellowish light.
Thus, if one module suddenly looses its color, ALL modules will have to be changed to keep the same color output, unless the unit has some sort of color compensation to correct the offset to keep the same color of light at a constant.
They contain the same LCoS light engine as does the larger 220 and 320 units and can do 3D.
Big thing with any new product is that they're going to have their obvious "growing pains" in their own form.
Here is some blurb on the topic of these "budget" projectors, including the 515 on the second page

Can you be more specific towards the audio setup in all booths?
If Sony Techs come to install the projectors, there should be no problem with these.
The Sonys have digital audio outputs only, 16Ch AES balanced or 8ch unbalanced ('Dolby Type') - what processor do you currently have, and is it the same type for all booths/screens? I assume all 35mm equipment will go?
What kind of automation/needs to you have - lights, curtains, masking? Was there automation for 35mm? What type?
There is a PDF manual for the Sony available - I suggest you get it from Sony to prepare for basic operation. Sony software is certainly not yet finished, but all functions are there for daily operations, and I don't think there are stability issues.

quote: Grant Chambers And the best news of all - they will send some of us to train at one of Sony's training centers.... wait for it... AFTER THE INSTALLS.
They are going to use you for grunt labor so that they can get the equipment installed as quickly and cheaply as possible. You will basically haul the equipment up to the booth, unpack it and set it into place. At that point, the techs will take over. They might let you stand on the sidelines and watch.
They will send one or two of the theater managers for training. The G.M., an assistant and the booth manager if you have one. Depending on how many people work in the theater, they might send one of your best operators ("booth leader") for training as well. The rest of you will be unceremoniously dumped. If your theater's management are nice, they might offer you a position as an usher, a box office cashier or a concession operator, downstairs.
I have seen this happen in two different theaters. One theater basically said, "We don't need you anymore," and, after the launch date, all the booth employees were let go. The other one offered the booth employees other positions but I don't think any of them took the offer.
Regardless of the timeline or the manner in which it occurs, your job is about to be eliminated. Get down to the unemployment office now. It takes a few weeks for the paperwork to be processed. If you want training as a dislocated/displaced worker, you'll need to get ahead of that ball as soon as possible.
Just by listening to you talk about how cheap your theater's management is, I can't imagine that they are going to keep very many, if any, of your booth workers. They have spent far too much money on this conversion. Unless they got some kind of grants or low interest loans or have done a lot of fundraising, they are likely to be in debt. The first thing they will do in order to make ends meet is to cut payroll. The first place they will cut payroll is in the booth.
You can be certain that they will get rid of most, if not all, of the booth workers. Unless you are certain that you will be kept on, long term, get out now while the gettin' is good.

False.
quote: Tony Bandiera Jr And if your owner is unwilling to spend the extra (Aprox.) $3k per screen to get a CP750....
Who says it has to be a CP750? What's wrong with a USL JSD-60? Or an ECI-60 to interface with existing processor. Grant says he has "DTS sound systems," so I'm assume 6AD. There are tons of these lying around that can be had for cheap as spare parts if one fails.

Sony replaces the optical unit under warranty. Annoying, yes. But not a cost issue to the exhibitor.
quote: Monte L Fullmer Oh, the IMB inside is rather tempermental-they use "Deathstar" HD's in the RAID that one will fail on occasion.
Please use the correct terminology. While most probably understand what you are referring to, Sony systems do NOT use an IMB; that is a component found in DLP projectors, which Sony is not. The media block may be housed inside the same chassis as the projector, but it is not an IMB. And show me a hard drive that will not eventually fail. I'm sure plenty of folks on here have replaced failed drives on Dolby, Doremi, and GDC.
quote: Marco Giustini Hard Drives fail, sure. SONY raid have 7 drives. 1 spare and two redundant. I still have to see an LMT that cannot be recovered just swapping drives.
Exactly. I've had LMTs operate for weeks with a bad drive until I could get out there to replace the drive, which is a 10-minute procedure.
Do I personally prefer a Barco or Christie projector? Sure. But I had to call to light some of the inaccuracies presented as fact here.
