Author Topic: Reflector working distance for SLC consoles Michael Schaffer "Where is the Boardwalk Hotel?" Posts: 4143 From: Boston, MA Registered: Apr 2002 posted 11-08-2005 02:03 AM                        What is the optimum working distance for the standard reflectors in SLC consoles (for both 2-3k and 4k setups)? Does anyone have the working distance measured from the front of the lamphouse (rather than the snood edge or film plane) to the front edge of the reflector or plenum?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 11-08-2005 02:05 AM                     What model projector are you mounting? The working distances are in the SLC manual here on the site you can download. It only specifies from reflector to film plane, but you can measure inside the lamphouse and then do the math.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

I want to check the reflector position in a number of SLC installations we have. I looked long and hard but couldn't find the information in the SLC manual. Where is it?  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Where did you find those numbers?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 11-09-2005 12:40 AM                     It's in the SLC manual just like I told you! (Try page 57) Christie, Century and Kinoton heads do not require a spacer for mounting on an SLC console, but Simplex projectors DO! If there isn't a spacer there, your Simplexes need to be remounted and aligned with the spacer (available from Christie). How many Simplex spacers do you need? I think I have several laying around here.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Thanks for pointing that out! We have 6 Simplex projectors mounted on SLC consoles. I will check them for correct alignment and the spacers as soon as I get to the location next time.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.
