The new cyan-dye only analog tracks MUST have a red LED reader, as cyan dye does not effectively modulate the infrared light found in white light (tunsten lamp) readers. Tests show that even with a red LED reader, the signal-to-noise of the cyan dye track is approximately -2 dB compared to current dye+silver tracks, so effective noise reduction (e.g., Dolby SR or equivalent) is highly recommended.------------------ John P.

and furthermore....Not much is going to be invested in trying to make an analog version of an A and SR card at this stage of the game. Ultra used to have an external card cage (The SRM-10) to use Dolby's SR cards (or, god forbid, the Copy Cat. 280 by SMART). When they developed their own SR knockoff that completed the system. Heck there is still a card slot left over for the JSYN-05 stereo sythesiser card that nobody gets anymore...as such it is the defacto Pink Card slot. I think Ultra has instead invested their R&D on the DSP-60. This might replace the JS line and be their "everything" processor.

It will be wonderful meeting Ray. I already have plans to use that SR unit too. Steve ------------------ "Old projectionists never die, they just changeover!"

For Ultra JSX 2XX / 1000 series: There is an Extended Range Noise Reduction card from USL, that goes into the slot next to the ISO-Type 1 NR cards. With the electronic, remote controllable switch card, there isa format, sometimes labeled "Future", or with later models "Stereo SR". Theese can be remote controlled. Witzh the manual switch card, no SR position is provided. You can adjust levels using the NR1 (A) card, and then swap the card for the Extended Range(NR2/SR) card. Swapping back would be neccessairy for those NR1/ A type prints, that randomly occurr. It might also be possible to use 3rd party cards, like CAT 280 and SR/A 5 adaptors, rthat can sometimes be found in dumpsters, at least here. It can be connected backplate between preamp out and matrix in (there's a bridge). Remember to set the reference level on the input measured with mv meter to 423 mV.With older Dolbygear, CP 50, 100, 200 it was just swapping the CAT 22 with CAT 280 modules for NR2/SR reproduction, but only recommended, if the rest of the hardware (CAT 64, optrical preamp, matrix, etc) was updated to a higher dynamic version. CP 55 required the external adaptor and changes in the control board layout. CP 65 was NR1 /NR2 capable with CAT 222 dual A /CAT 350 SR modules.

Gordon, I will try. On the other hand... soon to come newer equipment... First multiplex theatre in Germany to be closed. Recently announced was the closure of Freiburgs UFA Palast, a new 7 screen theatre opened 2 1/2 year ago. All halls digital and with curtains. To remain is the same age Cinemaxx, no curtains, Dolby A, but 9 smaller screens. When reading through all the bankruptcies in US ans over here, I have a feeling we can soon pick modern equipment from dumpsters. I am thinking of those motivated people, that ran the places, badly paid during work time, and then fired with short notice. Sad, sad, sad.
