Hooking up to a PA?

    I'm anticipating some upcoming gigs with my band at some venues where we will be hooking up to a PA. The amp I'm currently using, the Ampeg B-50R, does not have any external outputs of any kind, besides the headphone jack. So my question is, is it possible to hook up to a PA through your headphones jack? I'm pretty sure it is, but I'd like to be certain. If not, I guess I'll be buying a new amp sooner then I originally anticipated.

    Buy a direct box. About $50-100 and you're good to go.

    You plug your bass into the direct box, the box then has two outputs, 1/4" one goes to your amplifier, the XLR one to the PA.

    Some links to direct box makers:

    Often you don't even need your own DI-box because they are provided with the PA.
    I never go to a gig without a DI-box though - you never know.

    The SABDDI is perfect for this application. You can run the effected XLR output to the PA, which allows you to control your EQ at the PA. Then you can run either an effected or non-effected signal to your stage amp. Beetchen.
     
  5. Your headphone output will work, however since it's post-EQ and master volume, any adjustments you make on stage (incl. stage volume) will affect the FOH sound, unless your sound engineer is on-to-it.

    Failing that get 'em to mic up the amp, if possible. If the worst comes to the worst, you can plug directly into the PA mixer, then get them to send a feed from the mixer to your amp (thereby using it as a monitor). The bonus here is that you could ask more more than yourself in the mix...
     
  6. After everyone saying such great things about the SABDDI I decided to get one myself. Everything you hear about them is true (well the good stuff at least) I would say try one of those you won't regret it.
