Author Topic: Dolby A question Matthew Taylor Expert Film Handler Posts: 186 From: Essex, UK Registered: Mar 2004 posted 05-06-2005 05:24 PM                     I am thinking of buying a CP-50 for my home setup. I would like to know if Dolby A noise reduction would work on modern prints. I understand that modern prints are encoded for SR, so would I still get noise reduction with a CP-50? If not, I may as well just get a cheaper consumer pro-logic system to give me some sort of surround sound.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 05-06-2005 05:41 PM                     Dolby SR prints can still be played in (04) Dolby A and still get the correct Dolby A noise reduction.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 05-06-2005 06:18 PM                        Someone correct me if I'm wrong: Dolby says that playing SR through an A decoder is "compatible". But SR through A has never sounded very good to me.  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 05-06-2005 06:31 PM                    It's the other way around. You can play SR prints in A or SR but you can not play A prints in SR and expect it to sound very good.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 05-06-2005 06:58 PM                     Darryl is correct. I have never had a problem playing an SR print in Dolby A. Obviously, you don't get the benefit of SR playback when you do that. That may be why it didn't sound so great.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-06-2005 07:47 PM                     The fact that you get a good preamp and academy filter and eq in the cp50 is by far better than a home brew If you want SR then just plug in 2 cat 280T's  |  IP: Logged Gilbert Travin Expert Film Handler Posts: 101 From: Villeurbanne / France Registered: Jan 2004 posted 05-09-2005 06:14 AM                        Hi Matthew ! If you use a cheap home theater amplifier to decode surround sound (in prologic mode) you must use the CP 50 "Rt+Lt" rear outputs : the level of these outputs match with amplifier inputs. And sub channel is also decoded ! With this method you profit of A or SR noise reduction, but you don't profit of CP-50 front speakers equalization (Cat 64) ; for mono prints, you don't profit of the academy 8 kHz filter. The second method consists to use a home theatre amplifier with direct inputs (not cheap, alas !!!) : you connect the four ouput channels + the sub channel of the CP-50 to the 6-direct-input of your home theatre amplifier (surrounds Left and Right are wired together !) and you profit of all CP-50 possibilities  |  IP: Logged
