TS115A Woofer cutting out

Hi Guys,

Evidently - based on some other posts - there is some engineering issue with the TS115A units. Mine is doing the same thing...and I'd like to know if the problem has been identified and if so where I can send it for repair (if the repair is reasonable). I've inspected the unit and found no visible issues. Sometimes if you bump the unit the sound will come back on but it's only temporary. Perhaps it is a crack in the PCB and one of the traces is separating as the unit gets warm...

Anyway - is it worth sending to get repaired? Has this common problem been addressed?

Thanks! Ed

  • If anyone else got theirs fixed please let me know. If they cannot fix the amp I might just convert it into a passive stage monitor.

  • Hi Ed,

    Thanks for posting. Sorry you're having issues with your speakers

    It sounds like your product may need to be serviced.  Warranty and non-warranty claims are not handled here on the forum but I can point you in the right direction. Here are a couple of options that you could choose from:

    • Submit a Warranty or Service inquiry with our Technical Support team by logging onto the Alto Pro Audio Support Page.  Select Warranty or Service Inquiry from the drop down menu.

    I hope this helps!  Let me know if you have any additional questions.

  • Hi Bill,

    I broke down the entire system, cleaned all the contacts, re-seated everything, and inspected the PCB's and components for damage. I couldn't find anything. Based on this being a common problem there could be some type of engineering flaw in this particular amp design. I did talk to the tech folks and the repair cost is the same as buying a newer unit...so I'd rather do that and get a new warranty.

    Conversion to a passive stage monitor is a much better option from a cost standpoint...so that is what I'll do since I already have the necessary components in stock.

    After the inspection and cleaning I'm not having the issue...yet...but I cannot trust the unit for front line service.

    Hopefully the new units have this issue worked out.

    Cheers and thanks for the suggestion.
