Author Topic: DTS causing a pop on changeover Chris Byrne Expert Film Handler Posts: 102 From: Kirwan, Australia Registered: Jan 2003 posted 12-01-2003 06:32 AM                     We just moved DTS unit and reader to another cinema. Before it reverted to DTS without any disruptions; now it emits a loud pop through front speakers when it picks up the timecode. Similar to Josh's enquiry early today (or yesterday?), I am running CP55 processors. I have pulled and sprayed all edge connections and sockets in the CP55, as well as in the DTS unit and player. Aside from this, the unit / reader are performing well. Where should I look next?  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 12-01-2003 07:47 PM                        Just brain storming: do you have the same POP when you select DTS format on your CP manually? I've heard of strange anomalies when DTS reader's offset is set over 70. Bye A  |  IP: Logged Daryl C. W.

Is the pop heard at the 'exact' same time you fire the change-over douser? Does the pop not happen if you only start the incoming projector and not fire the change-over douser?  |  IP: Logged Chris Byrne Expert Film Handler Posts: 102 From: Kirwan, Australia Registered: Jan 2003 posted 12-03-2003 05:10 AM                     Antonio, the pop is evident when you push DTS on the CP55 as well as when the timecode is recognised and DTS pulls in via the reader. Daryl, my apologies, I have used the wrong terminology by calling it a 'changeover.' It is a one projector operation and the pop is instantaneous with the CP55 selecting the DTS format. I am a little puzzled.  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 12-03-2003 08:04 PM                        So it's not a problem from your DTS player, the POP is not coming from it but from the CP. I'm afraid can't help you further... Good luck! Bye A  |  IP: Logged Adam Martin I'm not even gonna point out the irony.
