Author Topic: cp650 non sync problem Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 11-12-2009 03:42 PM                        im having a problem with te non sync imput from a cp650, a few days ago somebody plug an RCA wire from a computer to the non sync 1 imput and the projectionist said that they couldt hear anything from the lap top, and after that when they re conect the normal non sync audio for all the auditoriums they found that the channel was dead. wath i did is to change the non sync imput to the non sync imput2 and change it on the dysplay. do you think is a broken board? mike moreno mexico  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 11-12-2009 03:56 PM                     Marin is normal when plugging in a laptop a stereo mini jack to rca to mute the sound from the computer but the sound should had been passing via the rca to the Dolby unit. is the gain levels configured correctly in the Dolby or perhaps they were omissed. Did you try plugging a cd player directly on Non-Sync 1 to see if you have sound? Some basic tests.

Make double check of connection, and input levels for NS 1.  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 11-13-2009 02:54 PM                        the non sync 1 and 2 levels are ok. and the NS1 still not playing anything...... mike moreno  |  IP: Logged
