Getting Odd Distortion

Discussion in 'Microphones (live or studio)' started by MigrantRecords, Sep 7, 2005.

  1. I'm running Pro Tools LE into a Mac G5. I use an ISA 428 and a vmp 4000e as preamps. The mics are C 414s and MD 421s. The cables are Mogami. The preferred cola is Dr. Pibb.

    ...and on occasion when I've double mic-ed something, when I listen on playback, it distorts in places. This has happened with horns and with guitars, as far as I can tell. A crackling distortion. In long, sustained notes. Very annoying.

    Yet, when I just listen to ONE of the mics, everything's fine. When I pan the two mics, everything's fine. But when they meet up in the middle, there's some minor distortion.

    The DigiDesign guy (after a 30 minute wait) told me he never heard of this before, and that maybe I was peaking the faders in the "mixer" (which is in the computer) and that I needed to experiment with using a Master Fader any time I play back.

    What do ya'll suggest? Do you agree? Is it a Master Fader thing and I'm just pushing the faders too hard? Am I peaking the mixer? Do you have any similar experiences?

    I'm not peaking the preamps, and when I'm recording, my levels onscreen stay in the green.

    Any advice is much appreciated! Thanks...!!

    Never heard of that before, sounds like a clipping problem but you say that isn't it. and i though it was mr. pibb not dr. pibb lol.

    did you try to turn down the volume? it might be as simple as clipping your output.
  4. Yeah, that's what the DigiDesign guy said. He suggested I use the Master Fader to assure that I'm not clipping the output. I'll work on that, try some things... the meantime, anyone else have similar issues?

    Thanks for the responses!

    where is the level in the master fader?

    have you tried just turning down the track faders...i hardly ever turn down my master fader.

    also, do you have any plugins in the tracks? i have clipped the tracks with plugins when i didn't realize it cause i was using a compressor after the plugin that was clipping. (usually eq before compressor)

    just watch the levels at EACH stage of preamp, plugin, fader, etc.

    start at the fader and work backwards until you find what is causing it.

    Sounds like a phasing problem, it is very weird though, t has happened to me before when using protools but not any other protocol just next time it happens try moving the mics around
