There's a lot of B.S. that goes on in the background here which I don't talk about to most people. You have heard bits and pieces but few have heard the whole story. Many people who have heard my stories think I'm just bitching and making stuff up. There are days when I have to fight to keep a positive attitude. Some days are better than others. The last two weeks have been difficult.
My boss keeps asking me, over and over, "You're sure this will improve the sound?" I keep telling him, over and over, "Yes, yes, yes!"
I have made it clear that there is NO WAY to make the sound 100% better just because of the design of the room. I tell him that the only way to get "perfect" sound is to put sound insulation on the walls and ceiling.
Side note: Aren't there some venues which have movable baffles to change the acoustics of the hall from "live" for stage performances and "dampened" for movies and things? I seem to remember seeing pictures of a venue that had large, black tapestries along the walls which were made of woven fiberglass or something. They rolled up like window shades. When you wanted "live" you pressed a button and motorized devices caused them to roll up. When you wanted "dampened" they rolled down. I don't know... maybe I'm dreaming.
Anyway, I'm telling him that there are other benefits besides simply improving the sound.
1) We will have the ability to use Dolby Digital for films. I won't be working there forever. Somebody is going to have to do A-chains on that projector at least once per year. He's not going to pay me $50/hr with a 4-hour minimum to do it for him as a private contractor. He's going to need redundancy in the sound system. Dolby will provide that redundancy.
2) We have to play the Met Opera on the same sound system. Right now, we are kludging the system together with "wire and gaff tape" to make the sound for the Met. A CP650 natively understands the AC-3 encoding the Met Opera uses. No more using signal combiners and junky solutions to "just make it work." The same thing applies here with DVDs and Blu-Ray.
3) Whether or not you like the Smart Mod-IIB, you must admit that its days are numbered. The company is out of business and there is NOBODY who officially supports those processors anymore. There might be a chance of finding somebody who will do repairs on the Smart Mod-IIB at a price. Furthermore, it will probably take a minimum of two weeks to get it repaired.
I'm talking about an afternoon's work to un-install it and box it up. One to three days to send it to the repair shop, wherever that may be. One to three days for it to be shipped back to us and one day to reinstall it and test it. That's one week right there. If the repair shop takes just one week to repair the thing, that's two weeks.
We're talking about simple stuff like slapping in a new card or replacing a chip. We haven't even considered the prospect of component-level debugging and repair. We haven't considered the possibility that the repair shop will have to order parts.
It is easy to consider that a blown processor could put them out of business for two weeks or a month or even more. Replace the processor now while you still have somebody who can do it on-staff. Save yourself the trouble right now. Get a processor that can be repaired in a short time. If it breaks, order a new card, slap it in and be on-screen again in a day or two.
4) Maintenance. Correct me if I'm wrong but doesn't the CP650 automatically adjust the LED brightness in the sound head in the fly? Even if it's doesn't, aren't there just a few clicks in the menu system to automatically calibrate it?
Meaning that the current sound tech from Fact Audio (mentioned in another message thread) could read the manual and do this kind of "upkeep" if it was necessary.
5) Michael (my boss) has to consider that I might not be working for him very long. I won't be there to "just fix it." There are many times, virtually daily, when I make repairs and adjustments to things. It's almost transparent. If you weren't there when I did it, you might not even know it happened. Even then, you would have to know the significance of what I just did or you wouldn't understand.
I won't be there to just tweak the lateral alignment on the sound head. This is a 10-second adjustment but you have to know how to do it or else you could end up being dead in the water.
I won't be there to power-cycle the cinema processor if it locks up after it receives a static electricity shock while somebody goes to adjust the volume. Yes! The Smart processor is known to do that. Search the forums. I posted the question myself.
There are a dozen little things that you have to know about the Smart processor. You can only know them by experience. The A-chains on a Mod-IIB have to be perfect. Even a little drift can cause them to sound like shit. They can be quirky and stop working for no apparent reason.
I know a trick to get a really good A-chain on a Smart. A lot of you guys might know it too. I have a tektronix 465b scope. It has an A-B add function plus polarity invert. Both the left and the right preamps on the A-chain have to be EXACTLY at the same level. Using the scope to make them perfect can do a better job than even the null meter inside the processor. This is "shit" you just have to know. It's non-intuitive. Even if somebody explained it to you, it isn't everyday knowledge to somebody who doesn't have experience.
If you don't replace that processor with something more up-to-date... something more future-proof... you could find yourself out of business until you can repair or replace it. There is likely to be no repairing it. You might be forced to replace it. I have found a good price on a used/refurbished Cp650 right now.
So, you claim your budget is being cut and you can't pay me to do my job? Well, you could find your ass out in the street a year from now when you have to spend THREE TIMES the price you would pay today!
Your car is running out of gas but you still have 1,000 more miles to drive before you get home. Will buying premium gas make your car run better? It might. But, even if your car runs exactly the same as it did on cheap, low octane gas, you still need to buy gas or else you might find yourself stranded in the middle of nowhere with no way to get home.
I'm offering you a full tank of premium gas at one-third of the price.
You don't have to pay but, be warned! This is the last gas station for the next 100 miles!
What's your decision?
