Question re: XLR-input on my bass

    Something I've been wondering about for a while...

    My acoustic bass has two input jacks on it: the usual 1/4 inch + an XLR out (see photo below)

    Forgive my naïvety, but... why have the XLR-jack on the bass itself/what would (or could) I use it for?

    ...Is it there so I can plug straight into the mixer and avoid any noise/tone coloration I would get from my amp? My GK 700RB has a Direct Out (XLR) jack and the option to bypass the amp's EQ, but I guess I'm just wondering when it I would be appropriate to use the one on the bass instead. And lastly, would I get any signal loss (or other problems) if I used both the 1/4 in. and XLR at the same time?

    These are outputs of course, not inputs. :)

    The XLR is balanced, which in effect means lower noise. And an additional plus is that the connector is more secure in place.

    But you need a balanced input on the amp to get any signal to noise improvement.

    And if you use both you will lose the noise improvement from the XLR.

    Only input(s) on my GK are 1/4 in... which means that using an XLR-to-1/4 cable to connect my bass directly to the amp is essentially pointless because the signal would still be unbalanced, and so there would be no noise-reduction benefits, right? Sorry if I sound as dumb as I think I do--circuitry and basic electronics have never really been my thing :-/

    You could go direct to a mixer using the XLR output, and depending on what bass this is maybe you also get phantom power from the mixer.

    Bass has an on-board preamp/EQ (uses a 9V battery), so I'm guessing I wouldn't need the phantom power.. unless the battery happens to be dead :p

    The preamp may sound better with the higher voltage though.

    The XLR output is used for recording purposes... straight into the desk.
