Great! Now start pumping sound! :)


In Topic: "infamous ribbon cable"

I wouldn't recommend a 're-crimp' with the original components : It will solve the issue now but will fail eventually. (The ribbon cable loosens its grip in the forked blades and moves causing intermittencies.) But, if you want to re-crimp the cable yourself, I would try to find a new header and connector that will fit their counterparts and install a new ribbon cable that will fit comfortably to the header and connector.

Though, my experience with the older display board, is to replace the board itself with the newer version (DSi : 138912-5).


In Topic: XTI4000 Phase reversal

This is a long shot : Have the display boards ever been changed or replaced in the two amps? Perhaps one of them (or both!) have the cable issue. If you should lose the good channel of one of the amps in bridge mode (signal is cut off at the display connector), then the bad channel would be 180° out of phase with the other amp! ie. The bad channel would interfere 'acoustically' with the good channel of the other amp.

To verify if you have the most current display module : Open the top cover; Locate the display board; p/n 138911-5 : the dash 5 is important! Anything below dash 5 should be replaced. If you need to replace a display module, get in contact with your local authorized Crown service center.

Thanks Bob! That was quite eventful! Hope the hack lasts long!


In Topic: CTs 3000 Popping/ thumping intermittent audio loss

I suggest to verify the 50p cable, located between the i/p board to the main BCA board : Remove the bottom cover and power the amp; Inject some 1KHz signal, at very low levels; While monitoring the output (perhaps with headphones) delicately flex the 50p ribbon cable and/or for that matter, the input cables (though, I've never had to replace any i/p cables on any CTS amp!)

Of course, I also recommend that you refurbish the output devices and replace the t-sens foam, located under the forked clamp of the HS heatsink of both output circuits.
