...for hooking up a keyboard player to our powered mixer?
we use it just for vocals.
i dont...i use the 'line in' feature on my pa system..but maybe im doing it wrong! ha!
You probably wont need one for short cable runs.
But get one anyways. You need at least one good DI box.
yes, that´s what i´ve been doing too, but i wanted to ask if using a DI box would be better, and why. (trying to learn here!)
Low impedance signals travel long distances better and are less affected by noise. 20 feet or so, high impedance is fine. Much longer than that an you'd probably want the DI.
Many DI boxes also have attenuation and ground lift, features that can sometimes be handy.
What is ground lift?
it lifts the ground pin, sometimes causing hums to be eliminated.
