Author Topic: sound cuts, doremi and cp-650 Byron Cabezas Film Handler Posts: 7 From: Santiago,region metropolitana/Santiago ,Chile Registered: Nov 2012 posted 05-04-2016 07:49 PM                        Hello everyone. I'm Byron, projeccionista work in a university hall. I have the NEC nc900c and 2000show doremi vault + IMB. my query is as follows: project a film that every time the sound was ragged. especially in musical scenes. when he finished the probe function again conflicting parties, and this time everything perfect. some time ago I happened with another film. but it was several months ago. that problem is ... firmware, cables.etc.? greetings from Chile. pd: sorry my English translator using google.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 05-04-2016 08:20 PM                     Do a forum search on 'CP650 Robosound'. - Carsten  |  IP: Logged Magnus Eriksson Expert Film Handler Posts: 121 From: Stockholm, Hägersten, Sweden Registered: Jan 2011 posted 05-05-2016 04:20 AM                     Just to make sure: if you follow the sound cable, from DCP2000 to CP650, where is it connected to the CP650? What input is used? "OPTION CARD 1/0" or "6-CH AUDIO INPUT"? If the latter, is there any device between DCP2000 and CP650? A D/A converter of some sort? /M.E.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 05-05-2016 05:27 AM                     IMB to CP650 could also involve the dreadful Doremi RJ45 converter, another potential source of failure. Get rid of it, solder a dedicated cable from proper S/FTP. - Carsten  |  IP: Logged Byron Cabezas Film Handler Posts: 7 From: Santiago,region metropolitana/Santiago ,Chile Registered: Nov 2012 posted 05-05-2016 01:03 PM                        Thank you very much for your answers. it became clear that the problem is the cat 790. if presented again I will try to reset the CP650. or change the format. greetings from Chile..  |  IP: Logged Magnus Eriksson Expert Film Handler Posts: 121 From: Stockholm, Hägersten, Sweden Registered: Jan 2011 posted 05-06-2016 05:26 AM                     If the problem comes back (and I´m afraid it will): 1) Like Carsten wrote, check the cable or make a new one. Make it as short as you can, use good shielded 2-conductor/channel pair and have as few obstacles in the signal path as possible. 2) If that doesn´t help, consider CP650 fw. 2.3.7.2 BETA. This never became an official Dolby release (?) but it has killed "robosound" on every CP650/Cat790 i have been dealing with. Btw, be very careful when updating a CP650. It can easily get bricked if you use improper equipment /M.E.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-06-2016 03:04 PM                     quote: Magnus Eriksson but it has killed "robosound" on every CP650/Cat790 i have been dealing with almost But it works well indeed.  |  IP: Logged Byron Cabezas Film Handler Posts: 7 From: Santiago,region metropolitana/Santiago ,Chile Registered: Nov 2012 posted 05-06-2016 05:10 PM                        thanks, Magnus.
