Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 09-01-2009 11:43 AM                     Check with Sam...when he was at Dolby, he had their rectifiers rigged with motors so one could adjust the lamps from the booth (The rectifiers were below). However, I would say that the IREM switcher would make more sense than anything for Cinemeccanica...IREM is an Italian company so it would be a domestic rectifier, they are LESS expensive than the N3 or G3 series and they consume about 33% less power for the same power output. So what would the advantage be to the High Reactance versions? The cost savings would allow one to have spare(s) of the EX series switcher IREMS and they are quickly changed, if needed and to date, I've never had to change one except a new one that had a control circuit problem...the rectifier worked...you just had to manually turn it on/off.

They are now modular and if a module fails the rectifier keeps on going only at a reduced power level. So with the modules there is no need to swap out the entire box.

We used the new Cinemeccanica MK2 projector for this location only which most of you might not have seen so here are some pictures of it plus the rail system from BACP which works flawlessly. The wheels were a temporary solution until the rails arrived so we had the projector on wheels to put it in show position when the 3D movie started about two weeks ago.

There will be a 'docking station' at each position. Demetris, I see you've fitted a rack mounted keyboard drawer. Here's something I like to use. http://cpc.farnell.com/_/kybac540-usbblk/mini-keyboard-with-touchpad-usb/dp/CS14295 Or for a really neat touch http://cpc.farnell.com/_/lcn-003/15-tft-lcd-rack-mount-monitor-1u/dp/CS13284?Ntt=rackmountkeyboard  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 10-31-2009 04:44 PM                     Hi Peter, Actually you could do away very easily with the Kinoton one. You could mount two metal beams across the leg position and place at the very ends hand adjusted fixed legs (like the ones already on the mount) but at the inner side place heavy duty wheels. Then it's a matter of actually 'hammering' down some stops to always place the projector at the same side and use a multipin connector either on the front or the back to move it between auditoriums. Will you be having 3D? If you are and using the Dolby 3D how will you compensate each time it moves since obviously the colometry will be changed due to screen?

EDAC sockets mounted on the wall will carry audio and control. Our own automation interface is added to each screen so only needs 3 wire serial between it and the console. (Our serial automation unit is so cheap that this is affordable and cheaper than instaling one in the console then wiring all the control back to the booth kit via the EDAC) As to the Dolby 3D, the screen surfaces are all being renewed as part of the job, they will be the same and are similar size, rake etc. I'm planning to take measurements in each screen to compare. If they are reasonably similar then it gets left alone, if not then I'll have multiple settings files, which will have to be uploaded every time the thing moves. Thankfully it is not planned to move it between screens often. Obviously for 2D content I'll have 3 set of measured colours files and 3 sets of macros.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-01-2009 10:43 AM                     Thats the same keyboard I use although it's badged under a different name here in the US. I dislike the monitor in a drawer thogh. With servers like Dolby where the monitor needs to always be visible then monitor in a drawer is awkward to say the least. If you have a remote monitor then they are fine.
