Amp warning, question !?!?

    Played a gig on Sunday that was sponsered by a group of people that bought a bunch of brand new equipment for a backline. They had an Ashdown 2/10 combo. I was the first to use it. 2nd song the speakers went out completely. The tweeter still worked, speakers completely gone. I plugged into the PA and did the best I could to compensate. The amp didn't recover. I shut it for a while (thinking maybe it had some sort of overload cutoff), but the amp was a gonner.

    My warning: Ashdown amps may not be all that dependable.

    My question: I had the amp set with the mids and treble at about 7, all the EQ boost buttons were out (inactive), regular and master volumes on 3, BUT I had the bass cranked to 10. I was plugged into the active input, and my MM bass was at about 3/4 power (volume and EQ). The owner of the amp claimed the speaker blew cuz I had the bass on the amp cranked.

    Any clues as to what may have happened. I feel badly about the incident, but I don't feel I was at fault at all.
     
  2. Heh, well it seems to me that if a bass amp can't handle having the bass knob cranked, it isn't much of a bass amp.
     
  3. I haven't heard of Ashdown completely shutting down, but I have heard of the volume dipping when it gets warm.

    Something fishy is going on.

    Sounds like one of the speaker wires came loose from the vibration. That would kill both woofers and allow the tweeter to remain operating. Shouldn't have happened, but it could have happened to any amp. A defect like that would show up in the first few days of operation, methinks.

    "10" is a lot of bass EQ! You guys should add a 1x15 to protect the poor 10's. :)

    Sounds like you clipped it and it shut itself down. With the bass cranked it takes alot of power to drive the lower frequencies and it may not have had enough.

    OK, many bass amps have EQ that can boost 15 to 20 dB.

    If without boost the amp is putting out ONE watt in the frequency range the EQ controls, boosting 15 dB would require the amp to put out 32 watts. A 20 dB boost would require ONE HUNDRED watts :eek:

    Pretty easy to clip an amp that way...clip the amp, kiss the speakers good bye. :(

  7. I can crank up the bass on any of my amps and the speakers don't blow. Ashdown is a very reputable company and I think the amp was just a factory turkey.
     
  8. Did it sound like the amp was clipping? If you were playing very loudly into those 2 10s with the bass boosted 15db, I would say that you probably blew the speakers.

    The amp sounded fine, till it blew. Also, the bass on my bass was only up a little past halfway, and the bass boost on the amp was off. With the amp volume at 3 it doesn't seem to me like the it should have gone. I also think that it must have been a wire that rattled loose - or a blown resistor or something.

    When I see the people again that put the show together I shall ask what the problem was. I don't like to put bad words out about a company - but if Ashdown tells them I shouldn't have cranked the bass - then I think their amps are worthless. If it was a fluke, a one in a million - and they own up to it being a faulty amp I will share the news.

    I play my amp with the volume on 4 1/2 with every possible bass eq cranked, even at 30 Hz and there has never been a problem. I'd say it was not your fault. Let us know what Ashdowns says...

    I'm in the house band for a jam night so I provide the bass back line. I never let anyone play my amp without having total control of the volume and EQ. I also bring as many speakers as I need to ensure that what ever these guys do, my gear is safe. I'd have had that combo sitting on another cab, a 210 or better still a 410.

    I dread seeing people heading for the stage with MM's. I really don't see why these basses seem to be designed to put out such a super hot signal.

    Given that this thread is nearly fifteen years old, I'd say the answer to that is a definitive "no."

    I would have to agree about maybe something rattling loose. I can also say that I have NEVER played with my bass dimed on either my active bass OR my amp.

    I've owned EBMM SR5's for years and never had an issue with a TOO HOT signal. There's this little thing called a VOLUME KNOB, and if turned a little counter clockwise can work magic.

    Ok but if 10 is too high for some amps why design it that way?

    Maybe you haven't had a problem, but your post indicates that you are aware that they are hotter than required.
