I'm sending the 4 track mag through Format 11 in the CP500 which bypasses NR and EQ just like it was a DTS unit. Seems to be working great. This was after I found I had the Center channel wire in the wrong position on the 6-track external plug!!! I'm feeling sorta stupid right now. Thanks for all of the folks who offered there ideas and help.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-12-2009 10:43 AM                        Don: notice that you would have needed 2-222 cards, not another 222-sra card. This gives you 2 channels of sr and 6 possible channels of A nr.

Your efforts will be well rewarded the first time you play a 4trk mag feature. Now you will be able to see for yourself how spectacular 35mm mag can sound, even on the earlier stuff; listen to a few films and it will put to rest Mark G.s highly questionable statement that 35mm mag is not much better than AM radio(?!) I don't know what he was listening on, but not to be impressed with mag after having to endure listening to mono optical all those years means something had to be amiss with his playback system. I have mag prints of very early titles like CAROUSEL and THE KING AND I and they sound nearly as good the DVD transfers. I have a few reels of CIMMERON (circa 1960), rejected because of over modulation which caused very mild distortion (analog distortion -- actually quite listenable compaired to the fingernails-scraping-on-a-blackboard digital distortion). And even those reels, distortion and all, simply sound great -- the recording engineer was the very accomplished Franklin Milton (UNSINKABLE MOLLY BROWN, ICE STATION ZEBRA, MUTINY ON THE BOUNTY, HOW THE WEST WAS WON), no slouch, he. The Franz Waxman score with the Roger Wagner Chorale has superb spacial depth with beautiful, delicate highs, bearing out what Steve already pointed out -- 35mm mag is quite capable of robust bottom and top end. True, I find that it's best to tweak the eq for each film you play to get the most pleasing sound in your particular room -- not much was standarized back then ala Ray Dolby referencing, so there can be quite a difference between mixes. But unlike Mark who seems to only be impressed with things digital, I think you will be very quite satisfied with what 35mm mag will deliver. PS -- anyone who questions whether or not 35mm mag can consistantly get out to 12hz only need listen to the damn 12khz trigger tone on the surroundtrack. If the recording engineer recorded high end in his mix, the system will play it back.  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 05-12-2009 12:18 PM                       It's always amazing to hear mag tracks. I did a lot of 70mm setups in the '70's and 80's and even without NR they sound amazingly good. This despite worn, low quality and misaligned (both for height and azimuth) heads, the tracks just want to sound good. 35mm is not quite as good, more noise, older tracks, warped film stock, etc., but sometimes it can still do amazingly well.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-12-2009 03:57 PM                        35mm-4 tr mag: "poor man't 70mm" Instead of picture and track, I once had my premieres printed on Fox hole film, striped and sounded mono on all 4 channels. I could fly in with one penthouse and a Dolby MPU and go: the operators were relieved that picture & track were not needed. (I know, I'm a chicken!)

Is that an option or something [what's it for?]. --jhawk  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Note, however, one should use the CP500/300 for such things as the Cat 222SR/A has too many limitations. Steve  |  IP: Logged
