V6 info

How long before you will have the native scope version masking screen?

If everything moves according to plan both the scope and regular 16:9 native frame is estimated to be put in production come October and will be available for drop shipping via AVScience in the US within November...

So, for anyone interested we´ll be showcasing a prototype MotoMask V2 @ Alcons Audio Pro-Ribbon Immersive Experience at the Upper Level, 25C of the High Performance Audio rooms.

I´ve included a 3D sketch of the room, featuring Alcons a full CRMS system, Trinnov pre-amp feeding AES / EBU to Alcons amps / processors and Barco LOKI 4K DLP laser @ 8500 lumens projector. Screen size is 212" 16:9 native (15 1/2" image width), 1-way masked to 2.40:1.

...the green stuff there are 1D QRD panels custom supplied by us for this specific show. These are actually quite cool, moulded using a new very light form of polymer plastic, so that each panel of 1200x300x100mm (47" x 12" x 4") weight only 2,8kg / 6 pounds. Can be attached to walls using velcro due to light weight, but these panels are custom made to accommodate a special M6 attachment using 4 points at the back for ceiling mounting and 2 points at the top for hanging from the truss. Might become available later on if people fancy them; MSRP would be typically 149-199USD per panel.

I'm looking forward to checking this out next week!

The newest V6 AT screen fabric is excellent - great demo at Cedia. That was one big screen too !





I could not see any texture / sheen or other artifacts at all !

Thanks Craig! We got a lot of positive feedback this year, and good amounts of both 78" x 118" as well as some 118" x 295" DIY / retrofit systems are now in stock @ AVScience, our exclusive US distributor and dealer.

What made the presentation even more impressive this year was the fact that the two stereo speakers (L+R) were placed outside the screen area as the sheer size of the room allowed for this. Having only the center channel placed behind the screen (+2x 21" suba) would often be quite revealing to any excessive acoustical blockage. This was not noticeable at all, confirming the very strong AT performance of the V6.

As for video we did a number of clips, but one is perhaps the most revealing of all when it comes to speckle, uneveness etc etc; intro of Art of Flight being bombarded by 9000 lumens from the Barco Loki dual laser. We passed - at least in my opinion - this critical test as well; agreed Craig??

Loki, however, is a bit limited in the contrast department, and for certain content the gamma used was not compensating sufficiently. Also, shooting Blu-ray content on such a huge screen (15 1/2 ft 16:9 native, motorised masked to cinescope) really also gave us some issues with banding, very visible mpeg artifacts at times... Still, on brighter scenes and when content called for it, sharpness was quite OK. Although the XPR DLP wobbling system reduces sharpness somewhat I could still make out the DLP mirror 'hinges'...

Absolutely. As far as I could tell, the screen was invisible. That's the first time I've seen a Barco Loki. I find I can now see some RBE on all single chip DLP projectors including this one. I must have watched 3 chip projectors for too long ! Overall the picture looked really good, especially considering the size of the screen. And the masking system worked quite well - it kind of caught me by surprise during and aspect ratio change !

One of my winter projects, will be converting my screen over to V6. Been wanting to do this for a while. I will get an increase in gain and less shimmer on bright white scenes.

Sounds like a SOUND plan Mike! Looking forward to hear your impression once installed!

[AVSMike]

Ordered the screen fabric today. Once I get it, I will have to find a weekend where I can pull masking system and then screen for install. This coming weekend is out, since I will be out of town. Taking son to look at a school.

[AVSMike]

A few things arrived yesterday. One of which was my V6 fabric. The screen fabric is the prepackaged 2 meter by 3 meter material. Packaged very nicely. I wish I had time to install this weekend, but not going to happen.

So you currently have a screen with less than .8 gain?

[AVSMike]

So you currently have a screen with less than .8 gain?

Yes, real world gain on EN4K is about 0.75. V6 is 0.84, so I will gain about 12%.

For those that are retrofitting V6 onto an existing frame. If the frame is a low cost lightweight frame, you need to be careful, that you do not tension so tight that you make the frame hourglass shaped. Is is really only a problem if you have a large screen or a pretty good sized scope screen and a lightweight frame. What I would probably do. Get four pieces of 2x4 that are longer than your screen height. Lay them out so that you have two pieces that hit at 1/3rd points and the other two under the  ends of the screen.

Measure the viewing height of the frame and how big the lip of the frame is. If the lip is 1/4", then get some 1/4" blocks of wood. Fasten these blocks onto the middle two 2x4's so that they are viewing height apart. Now lay the frame face down on the 2x4's. The blocks will now, not allow the frame to bow in, when tensioning the fabric. Now just install the fabric like normal.

If the frame was really large, you could do the above and once finished, before removing the frame from the struts, install a couple braces on the back side, so that the screen can't bow in. You would need to add a spacer on the wall to move the wall cleat out the same as the thickness of the brace on the back.
