    I'm pretty sure you may be right there, I think when you switch an amp off it creates a power surge, hence the customary 'pop' on large amps/pa's.

    Teaches you to plug all the leads out first in future i guess! :p

    I can't imagine another reason, though the pc knocking off too shouldn't have happened I don't think...

    Ah I mean the surge goes through the guitar lead, and into your sound card. They're not made to take any kind of electrical current, as all they're really made for is headset mic's I imagine.

    It shouldnt be too big a deal, you could get a new pci sound card for next to nothing, or even pick one up completely free of charge over on the Free Stuff section of adverts.ie!

    I would say no tbh, it can't be a good idea really... Why is it that you want a head going directly into your pc?

    Is it an amp and mixer all in one? Or are the speakers powered by a seperate amp?

    i think its an amp and mixer the speaker outputs are amp style but i dont have speakers for it its in my pc because its the cheapest mixer i could get you see theres a gig in august and i neeed to broadcast it so i would take a line from the main pa into my head into the pc and have some spare channels for mic and stuff


    i was thinking about connecting the headphone socket to the line in and hope the headphone line aint surged

    ok so im thinking maybe if i run a line from the headphone jack on the PA to the line in of my pc as opposed to speaker out into microphone
    would it be ok without putting my soundcard at risk or even plug the monitor output into my line in would i be ok?

    The Line-In on your soundcard is designed to be connected to devices that run at line level (around 316 millivolts RMS). If your PA has an output that gives about that it should be fine. The headphone jack should supply a voltage of no danger to a line level device.

    What you originally did was connect a signal well past line level into a mic level input designed to take signals well below line level and it may also have been amplifying automatically.

    Note that something refered to as 'line level ' on a piece of professional audio equipment may be at a higher rating (1.228 volts RMS).

    all i know is that its a 200 watt head so i would be safest with headphones into line in setup?
