I play in a fairly busy classic rock band and two years ago we purchased 2 XTI 2000 amps and JBL mains and sub for live sound.
About a year after purchasing both amps intermittently had channel 1 cut out or simply not work during set up and then magically start working. It represented a real diagnostic nightmare and it took a while before we were sure that both amps had a problem! Subsequently the amps were returned for maintenance and were told that the controller board flat cables were defective and they were replaced. Service was great and both worked when they were returned.
Almost one year later to the day we started to experience a similar channel one failure on one amp. I called for service and because of our tight schedule they sent me another controller board which I replaced (very simple). Great service once again! It worked fine for a little while (30 days) and now channel 1 is not working reliably again.
In addition the other amp (we use for monitors only) has a different diagnostic but channel one is not working (intermittently). I’ve spent at least 8-10 hours determining that it is the amps. Both amps will be sent in for service tomorrow.
Crown has great service but my question is - are they reliable? These kind of maintenance issues are a real pain! If it happens to us again these amps will up for sale no matter how good their service department is!!! Is anyone else having problems out there???
