Author Topic: second external input to CP50 Jeff Else Expert Film Handler Posts: 125 From: Detroit, MI, USA Registered: Nov 2006 posted 11-10-2009 10:09 PM                     is there a way to make a second external input to the CP50 besides non-sync? my guess was into the "in from surround adaptor" on the back, with "future format" selected, and i got nothing.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-11-2009 01:18 AM                     There is a duaghter board to allow the mag to go through the EQ the future is for an external SR adapter  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-11-2009 05:44 AM                        Good luck obtaining any og this stuff now that Dolby no longer supports any of this. Simple outboard switching into the non-sync should be all you need. Otherwise, newer processors (CP-45, 55, 65 or new Dolby or USL should work.

The Cat 223 is the card Gordon mentions...it was only available for later CP50s too (there will be white plug in jumpers into mating sockets if your unit can support the Cat 223.

You can inject your signal to the cat160 inputs, where the signal from the SRA5 enters CP50. Then select the input through "future format", and have matrix processing and EQ. Watch out the input levels so you don't overload Cat150xx. You may also use CP50 as an EX processor with the same configuration.

USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 11-11-2009 09:06 AM                        Is there a way to do this with the manual switch card, or is "future format" only available with the automation card? If I remember correctly, the regular non-sync input on a CP50 does not pass through the EQ cards at all. Edit: to answer my own question, the SRA-5 manual says that the automation card is required.

You could use projector 2 optical if available. Regal does this on all their 55/65's to pass audio from alt. content. You would need to pad the input with a couple of resistors on the +/- of left and right. Easiest and cheapest way.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-11-2009 06:54 PM                     with the 223 the audio goes through the eq and fader another option is get the DTS relay board for a CP50/200 and break the B chain with it  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

For those that do want to use projector 2 (which should be occupied by an actual projector, I say), use a pair of 47K resistors for EACH channel. That is, put one on + and one on - for each channel...then hook up any consumer -10dB (RCA) source and enjoy...your levels will be just about right. Works on any Dolby transformer or active balanced optical preamp.
