Since Oscar and Bill have chimed in and I don't think USL has a rep on site....yet!Ultra Stereo also has a monitor that will take a post crossover low-level input (bi-amped) and that is the CM-60. You must move the links inside and used the DB-25 connector to use this option. Of the things that Dolby could have dropped on the CP650 for cost savings, I can very much see the crossover card. It certainly was adequate but wasn't the best and added to installation time (needing to wire two lines from the processor to each amp and to the monitor). It's lack of CD-horn boost and screen loss correction are also minuses. Sure you can use the treble control to kinda make up for it but the Cat. 683 doesn't compare as favorably as other manufacturer's units. I don't think most people here are getting that the CP650 isn't an upgrade persay to the CP-500. The CP650 seems to be built for the mainstream exhibitor that is running first run films. All of the user formats are "canned" rather than user creatable. This isn't necessarily a bad thing. There is a cost vs flexibility issue and the CP650 is cheaper than the CP500 for an exhibitor and will give them every thing they need to run today's films. I have not been given any official notice that the CP500 (or CP65, or even the @$@#$ CP45) are to be discontinued as a result of the CP650s introduction. The CP500 is certainly more flexible. The jury is certainly out on how well they handled the digital implementation of the noise reduction. I'm waiting to see, feel and hear it. I do welcome the PC interface for tuning and the P1, P2 LEDs on the front panel. Steve ------------------ "Old projectionists never die, they just changeover!"

Scott, Scott, Scott....<sigh>Since I never mentioned that I used Altec speakers (on this thread, at least), lets just presume, for a moment, that Mark and I know each other and he knows I use Altec in some locations (where appropiate) and that this was a little jab for those in the know. Mark has even mentioned that he has been the Uptown (at least to see Gettysburg). Sooooo, that said IT WAS A JOKE! Cuz, if using an "upgraded" Altec with Mantaray horns (constant directivity), they would need the same kinds of boost as say JBL. Futhermore, if the HF section was truely flat response, then putting a screen in front of it that attenuates anything above about 9KHz would attenuate ANYTHING (old, new or what have you). Of course you could start to measure perforation spacing on the screen to optimize the screen loss for the particular characteristics of your particular horn/driver combination to minimize the loss.
So Scott, do you see just how a joke fizzles when one has to explain it? God knows, I've stopped laughing about it already. <sulking> This could have brightened my day :'( BTW. The Uptown's Altec A-4s...are stock!<surprise> They are running with genuine Multicells (a pair of 1005 horns per speaker) and 515B bass drivers. When I "upgrade" an Altec, I retune/report the cabinet, switch the driver or recone it to a 515G series, change the diaphragm over to a 299 series and change the horn to a Mantaray. Now if you wanted to hear a partially "upgraded" Altec. The Senator is the place, they have JBL HF sections but the bass cabinets and drivers are Altec (515-16G). The Boyd in Bethleham, PA has fully upgraded A-4s. The Lyric is an example of fully upgraded A-5s. Have a happy day :-) Steve PS, anybody reading this with the thought of anger is reading it wrong.
