Author Topic: CP500 automation problem Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 04-27-2008 04:23 PM                        I have one CP500 which will randomly stay on mute at the show start rather than switching to the auto digital target. It's the kind of problem that will happen 2-3 times in one day and then might not happen for a week. When it happens, all I have to do is press the auto digital soft key. The auditorium has a Xetron XCN lamphouse with the Maxi-12XPC automation unit. Any thoughts would be greatly appreciated. For what it's worth, I have had this happen on other houses with a CP500, but it is so random and infrequent that I don't think I could consider it a problem.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

If it is 1.50-1.61 there is no telling what oddities you will have. 1.65 is the current most stable firmware and 1.31 is also known to be very stable.

Wouldn't it be easier to just switch directly from non-sync to digital at the start of the show?  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 04-27-2008 08:31 PM                        Brad: that is TOO simple!! I go even further: I add two cheap relays across the changeover coil; switches between "10" and "61", Works fine is most platter theatres.

How do I go about eliminating the Mute at show start? Are there things external to the CP500 that could be causing the processor to not switch out of non-sync? I have one that does this frequently enough to be an irritating, if random problem. Then I have another that will do it about 1-2 times a year. Our sister theatre has one that's started doing this from time to time.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

See if that doesn't cure your ills. It will definately prevent other ills (like dumping your entire memory and leaving you with no sound unil you bring the levels up on the preamps AND the outputs). Your service engineer should be able to do this in no time. The firmware might be available here on Film-Tech too. If you do end up doing it yourself...be sure to be using load500 version 2. Also you should know, if the the update is interrupted for any reason, your CP500 will be dead. Steve  |  IP: Logged
