Author Topic: CP55 & Smart mod8 advice! Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 08-02-2009 05:30 PM                     We have a Mod 8 that is only used for mono and digital sound,it falls apart in sr or stereo A but i have a CP 55 not set up for sr or split surrounds just sitting here. The mod 8 is excellent for Dolby Digital , D.T.S and i really like the circle surround. We are set up for 7.1 with Crown xls 602 amps. My question is could i get away with using the cp55 for analogue but keep the mod 8 connected to the amps for digital? In other words both the 55 and mod 8 connected to the amps at the same time?  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 08-02-2009 07:44 PM                     Please research this resource for multiple connections: http://www.rane.com/note109.html I think you will find all of the answers there.

Overall I'd throw the Smart in the dumpster and use the CP-55 for all formats after doing the proper mods to it. It's still a dam good processor!

Yes upgrades to the cp55 is the ultimate plan but money is so scarce right now. I worry about playing Back to the future in the fall in mono How do you think digital would sound through the cp55 without the upgrades?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-03-2009 08:49 PM                     You'd have just mono surrounds... not split as they should be. The NR is also going to be askew with only type A available. Although the Dolby Type A might be better sounding then the NR on the Smart.  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 08-05-2009 11:38 PM                     What if... I put a switching device between the cp55,mod8 and amplifiers? As a temporary solution of course.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 08-06-2009 06:34 AM                        LCR & sub will be fine in Digital. AS Mark said, you will only have mono surrounds (which may be all there is). Be sure you tie L & R surrounds together so no information is lost. BTW: When Dolby Digital was launched, the cp55 and 65 was all there was in recent processors. I assure you that (except in optical) they are perfect for a DA20 and probably well ahead of anything Smart ever made under their own name. The SR upgrade is common and I still have many (30+) in stock. PM me privately if interested.

Theres one on ebay right now.  |  IP: Logged Jarret Chessell Master Film Handler Posts: 288 From: London, Ontario, Canada Registered: Jan 2009 posted 08-06-2009 07:40 PM                     Can you not send the sub signal from a DA20 or DTS directly to the amplifier??? (Which I guess would also suggest you can't have it hooked up for analog audio at the same time?)  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 08-10-2009 03:15 PM                     Louis, You Got Mail!

Victor I too recon the CP55 upgrade  |  IP: Logged Paul Trimboli Master Film Handler Posts: 274 From: Perth Western Australia Registered: Dec 2002 posted 08-11-2009 06:27 AM                     The other option is to do what I had done after some advice I received on here and that is to mix the surrounds down into a mono channel and feed that into the AUX inputs and then feed the subwoofer channel into pin 14 on the J18 test connector (the D connector along side the outputs on the back plane)- this IS then controlled by the fader with the downside being it is not switched as you change formats. My way around this was build up a smaller board that used the LED outputs on the Cat 321 card to trigger a transistor which in turn turned on a relay that I had wired the sub signal into- this way when I changed formats the sub would also turn off. All this was done with a stock CP55.  |  IP: Logged Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 08-11-2009 06:55 AM                     quote: Demetris Thoupis Which means you will have a constant level of the subwoofer. Bad idea. At least with DTS (I'm not sure about Dolby Digtial) that is how the manual says to set it up on a CP-200.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-11-2009 09:33 AM                     That is correct that DTS did suggest that the sub not have a fader control on the older un upgraded cp55 that doesn't make it right and it also didn't work all that well either  |  IP: Logged
