Thread: RCA vs Digital

  1. #1

    Default RCA vs Digital

    Curious if anyone has ever noticed a difference on a major PA. Normally, I work/DJ small/medium raves and everyone just uses digital. I'm assuming it's cause it's easier and sounds better (duh) but now I'm working a major festival with a very nice PA. The back line guy was using RCA and when I asked why, he said it doesn't really make a difference. I figured, of all places, a major festival would have used digital. Thoughts?

    Holy crap. It can make a huge difference. Think about feedback alone with using a data signal vs. analog signal. Digital outs are also balanced as opposed to the unbalanced RCA alternative. This just hurt my brain. What festival was it?

    I think he means connection between the CDJ's and the mixer, not mixer-FOH. I can easily imagine the difference is not audible, even on a festival PA.

    That I can agree with.

    RCA is a plug format, not a type of audio.

    You can transfer digital over RCA plugs.

    Back when I first put together a full CDJ-2000NXS and DJM-900NXS setup I plugged both the regular Line RCA and Digital to the mixer and to my ears there was a tiny difference in which the Digital sounded a bit more pronounce on the highs but hey those were my ears and not a RTA. I haven't done any comparisson on my new NXS2 setup but I have both line and digital hooked up in my coffin at all times.

    But to agree with others above, regular Line output can be susceptible to noise as it is an unbalanced signal. Digital can still be susceptible to ground loops and RF interferance but the odds of it happening are very very slim.
