Author Topic: Screwy sound from XD-10 Frank Dubrois Jedi Master Film Handler Posts: 896 From: Cleveland, OH Registered: Mar 2005 posted 11-09-2007 01:42 PM                    In analog, there is little if no volume from the left and center channel, but the right channel is fine. In digital, the left and center are fine, and the right is slightly lower volume. The only strange thing I see is the clip light on for the amp that controls the right channel. Any insight into this?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-09-2007 04:03 PM                     If memory serves the xd10 has nothing to do with analogue what processor is it mated to  |  IP: Logged Frank Dubrois Jedi Master Film Handler Posts: 896 From: Cleveland, OH Registered: Mar 2005 posted 11-09-2007 04:22 PM                    I haven't been there for about 2 weeks, but I dont remember another processor. Just the XD10 equipment and amps. Everything worked fine, then just went nuts. I guess I will have to recheck the equipment if your correct.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-09-2007 04:24 PM                     Disconnect that channelos input and if the clip light stsys on then the amp is bad on that channel. Gord is right XD-10 has nothing to do with analog. But if your analog is also bad then do a quick A-Chain to locate the problem there. It should be painfully obvious where it lies if there is a problem there.

You must have some other form of processor in the rack that is at fault. In regards to the levels in digital, that is also the fault of your analog processor.  |  IP: Logged James Westbrook Phenomenal Film Handler Posts: 1133 From: Lubbock, Texas, Usa Registered: Mar 2006 posted 11-09-2007 04:26 PM                     Or his solar cell in the soundhead?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-09-2007 07:51 PM                     Hopefully he has a reverse scam unit in the projectors there. A bad LED can cause masive channel imbalance but that probably wouldn't keep the light on the amp lit.

They are old units. I believe from 97 or 98.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-09-2007 10:00 PM                     I would say they have seen their useful life just by the age. I have not seen any last that long in daily theater operations... in places that get used once in a while... yes. You can look at them and tell if individual segments have failed. You'll see dark spots or a dark rectangle if multiple segments are out. I believe 2 rows of 12 LED segments are in the LED.

Could that happen with a bad LED? I thought that maybe things would slowly deteriorate.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-10-2007 09:36 AM                     It absolutely could be fine one day and die the next day. Look at the LED's in your complex through a piece of black film(not opaque) to cut the brightness down. Any segments that are out will be obvious. If all is fine then the problem lies elsewhere. As far as scanners go if you have Kelmar's with a white and gray power supply box that power dupply also commonly fails.

Has this auditorium been closed down to diagnose and repair this problem or are movies still being run with "Screwy Sound" to paying customers?
