Hello. First off I've been a Crown fan for many years & have never had any problems with the amps or blown speakers ( I have knocked the power out at a few venues with the older models!). I have a XTI2000 and have now replaced two cones - one on an EAW250 & a JBL JRX100. I'm currently running the amp with 2 JRX100 subs. The problem I'm having - It always takes a while for a signal to display on the amp. I'm running 2 QSC 12 powered for the high freq' & run a signal via a zone to the Crown amp. When I do get the signal & the bass bins push air - it may be a few minutes or a hour or so & no bass. There are no error messages on the amp ( which is still powered up). Last night, it happened again, and out of frustartion I tapped the amp near the input & it came on. I'm thinking this is an issue with the inputs - anyone else had a similar situation or is there some other setting I should be checking ? I'm very careful about my levels & always use limiting, but of course, still managed to blow 2 cones ( probably when the sub came back online). Any suggestions or help would be greatly appreciated.
