I ate a few not only in the Motion Picture Industry, but also in the Broadcasting Industry. They are really not that hard to deal with, and are usually are easy to eliminate.  |  IP: Logged Tom Kroening Expert Film Handler Posts: 214 From: Janesville, WI USA Registered: Oct 1999 posted 06-13-2001 04:43 PM                     Paul, It's definately not a ground loop problem. Its more of a buzz like those hairclippers that they use at the barber then a hum. It doesnt always come out of the auditorium, but always comes out of the SMART sound monitor. The monitors normal light is on and the backup light is flashing. Funny thing is the switch is set to the normal posotion. There seems to be the same hum coming from the exciter bulb itself, although it could just be the sound monitor that im hearing since they are in close proximity.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-13-2001 05:05 PM                     I believe you probably have a smart combine excitor supply and monitor When the bypass is flashing it indicates that the backup ps is in use The problem is probably the bridge or the regulator module  |  IP: Logged Tom Kroening Expert Film Handler Posts: 214 From: Janesville, WI USA Registered: Oct 1999 posted 06-13-2001 05:12 PM                     Hmmm, interesting. We have two or three extra smart monitor/exciter supplies. Would you recommend swapping parts or the whole unit itself?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-14-2001 12:43 PM                     Simpiler to swap the whole thing  |  IP: Logged
