Author Topic: Do you think that mismatched cable length makes any difference for FOH speakers?  (Read 3664 times)

At many of my typical bar gigs, I generally put my mixer rack right next to the stage and behind a FOH speaker stack. Because it is close to a stack, I sometimes use a 10 ft. XLR cable to feed the near stack and a 50 ft. cable to feed the far away stack. (They are powered speakers with built-in dsp, so just one full-range cable goes to each stack.)

Do you think that the difference in resistance between the two lengths is enough to notice any difference in sound or level from one side to the other? I do have several 50 ft. cables, but am usually too busy/hurried to dig them out.

During shows, I have noticed some slight differences between the two stacks, but I always thought that was caused by the proximity of walls and furniture or the speakers themselves being imperfect.

Should I make the effort to use a 50 footer on both sides just to balance things up?

There will be no noticeable difference.

Definitely no. Especially not with line level audio. It would need to be more like thousands of feet before you would notice a difference.

Which would not be noticable in a typical bar gig, over the noise of punters and given the poor acoustics in most such venues.

Just don't worry about it....

We haven't answered this question for at least several years...

Short answer is NO.

Not until the cable length difference becomes greater.  And then it's not a time difference, it's a level/frequency response difference.
