Snell XA 90 Powered Sub Amplifier problem

Recommended Posts

I have a nice pair of Snell XA 90ps with the amplified powered subs (2 in each box). On one speaker the amp is not working, it powers up, red LED illuminates on the front of the cabinet but no sound.  Drivers tested fine and produce sound, just not from the amp. Anyone know how to get this repaired? All of the other drivers are working fine, just the 2 - 10" subs are not getting powered by the amp. I'm told that the micro control board goes defective on some of these.  My plan is to sell these as they are too big now for my living quarters but I want to have a fully functioning pair to sell vs. something that needs repair.  BTW if anyone is interested in them, repaired or as is, message me.  These are awfully nice speakers and were right at $7K a pair when new.  A good deal awaits someone looking for these!

I fixed a powered sub once by opening it up and discovering a fuse inside had blown. Check your sub for fuses.

Have you tried disconnecting the woofer itself from the cables and testing it by itself to ensure the woofer is not blown?

Tomknow,

 

I realize I may be coming in late on the conversation...but I have 2 90XA's also, and I've had the sub-amp issue more than once.  I was able to send one of my sub amps to Snell when they were still in operation.  They sent me a "refurbished" sub-amp in return, that had been repaired.  Now, I have an issue with the opposite sub-amp; it either hums very loudly, or it blows the fuse when it first fires up.  Yes, there is a fuse; it pops out just below where the power cord plugs in the back of the speaker/amp.

I'll have to resort to finding a local electronics repair shop and hopefully find a schematic out there somewhere...

Kevin
