I've had (2) XTi 2000's and an XTi 4000 for several months now and all functioned perfectly - until last night. I hooked them all up to my laptop with Band Manager. After updating firmware, it recognized all three amps. I loaded some JBL tunings in both of the 2000's and checked x-over points and other settings loaded with some of the SRX tunings. When I got to the 4000 and tried to load the JBL tunings the amp popped and shut completely off. After turning pressing the power button to off and back on again, it booted up fine but now there is no output to the speakers at all from either side!
Anybody else have anything like this happen before?
Is there anything I should try before I take it in for service?
XTi 4000 stopped working after loading JBL tuning
