On the cp55 and cp65 the suitcase jumper for surround feeds a sum to the surround speakers
on the cp65 on sets it nonsysnc in the 4:2:4 mode only
Using the SRA5 path is the only gracefull way on the CP55

Actually removing the NS Surr jumper on Cat 243 feeds the surround decoded by Cat 150 from the NS input to the surround output as desired. However the NS L and R feeds directly to the L and R output without decoding.

To get a full prologic decode (without sub woofer) a rather simple modification on Cat 243 is required. Just remove INC D84 diode and add another diode as shown:

This modification applies if no SRA5 is installed.

As much as I'd enjoy taking a crack at modifying the Processors at work, I will refain from doing so. They aren't mine, I'm not that far trained, though I'm confident I could do it, but I doubt I'd get permission from Regal to make the modification. Remember, right now I'm new to them, so they'd assume I don't know much, 'till I get my Certifications. [Wink] Besides, while I'd like to have it, it isn't a necissary thing. But if anyone else tries it, let me know how it turns out, may fuel my plea later to make the mod.
