Speaker Wars: Return of the Surround Sound
So Charley Knox and I spent the university's bonus holiday today in Strosacker, finishing up the process of hooking up the new surround speakers that were installed in August/September as part of the University's upgrades in Stro. We're now back to full Dolby Stereo w/ Surround; all that's left is to hook up the new Left Extra/Right Extra speakers (over the doors at the sides of the stage) and modify the Dolby processor to route non-sync sound (tape/CD/iPod/etc.) through those speakers instead of the main screen L/R channels (that way, we can play non-movie audio with the screen door closed).
We also disassembled and rebuilt a large part of the #1 projector, replacing some damaged parts that we found while replacing a busted gear back in August. Of course, we had to dig deeper into the machine this time, and found yet more bogosity :-(. Turns out that all 3 bearings on the sound head horizontal shaft were toast (we installed replacements for the two on the drive side of the machine, but didn't realize when we ordered parts that the one on the operator's side is toast as well). If we'd looked closer before, we could have seen the dented spot where some bozo at Cineplex Odeon whacked it with a screwdriver. Idjits.
BUT...now that things are back together, the machine is humming quietly, doesn't make the nasty sticky-bearing-caused gear-grinding noise every time we shut it off, and has zero play in the main vertical shaft. We should be in good shape for Sci-Fi Marathon 30 and the Spring 2005 semester.
