Author Topic: Moving a digital projector Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-20-2009 09:37 PM                     Steve... Am just trying to keep costs in line on racks... sure the more expensive line is nice but hard to justify for a simple server system in a booth. Raxess makes an identical quality rack to Mid Atlantic. I used to sell both brands back in Chicago amnd we do at CLACO. I finally weaned my boss off Home Equipment racks! Raxess just happens to have a deeper rack available in the less expensive line. Dolby sends out 28" deep racks and it's a bit tight on the back of the DSS-100 where the power cords go in. You're also exhausting quite a bit of hot air from the power supplies into a very shallow space... The aux fan that Dolby includes with the rack is very definately needed. At one location I cut holes directly behind the fans and installed guards so the hot air can exhaust straight out of the rack. Give software to the booth mongers... NEVER! Tristian, As for front space for MAster Image I can't remember what they like you to have but if you turn the unit around you c an get the shroud of the wheel right up to the lens and I'm pretty sure that 14" depth is more then enough. UNless you're using a 1.0 ratio lens the image on the port is still smallish... as-is the Master Image filter size.. so getting the wheel as close as is possible to the lens is mandatory. So far I haven't encountered any space problems with down to the 1.25 ratio lens. RE: Color space and MCGD. If both screens are manufactured at the same time they usually come out very close to each other. Of course it's prefered to have color files for each 3-D location, and if you have some very poorly manufactured screens (like the new washable one) then you may have to load in proper files for each room... otherwise if the two rooms measure very close just run with one MCGD. If the port glass is off at one screen then get the same exact port glass for both locations involved... port glass is not that expensive and if cut fomr the same sheet of glass they will match perfectly!

They are built more durably and have handles and covers to make them easy to move. I used one of these for the sound system for my 35mm home setup (processor, amplifiers, monitor, CD player) and occasional moves are super-easy. How easy/hard is it to change the lenses on a projector? Do they have some sort of bayonet mount, or must the unit be disassembled in some way? They aren't cheap, though.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-21-2009 08:36 AM                     Yea, if we were moving between different locations but we are talking about moving within the same booth. Lenses dismount with the flip of a lever if you don't have a MALM on the front. Barco is a bit more difficult but still pretty easy. The new series of Christie lenses is supposed to eliminate the need for the MALM in most cases.

We'd be using the pedestal that Barco supplies.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-22-2009 11:22 AM                     On the BARCO base be sure you have enough of the special(Metric) hardware to mount things properly. This hardware is very difficult to find... On the DSS-100 (if you have one) I also reccomend supporting it at the rear. I mounted a complete Dolby Server system with NA-10 once in a DP-100 base.... The NA-10 had to go in the rear. Mark  |  IP: Logged
