    Just want to confirm your connections here.....

    Are you using an XLR -> XLR mic lead to connect the Summit to the 002?
    If so, this is bad.

    Use an XLR(female) -> TRS(male) to plug the Summit into one of 002 channels 5-8.

    If you are already connecting in this manner, then disregard that and check all you leads, try different 002 inputs etc.

    On the back of the digi002 there are 8 analog inputs. 1-4 have both XLR and 1/4" sockets, while 5-8 have only 1/4" (TRS) and a -10/+4 switch.

    Plug into input 5 and make sure that switch is on +4db. Select input 5 on the channel in PTLE and you should be set to go.

    in principle yes

    but you could experiment with a little gain on the 002 ... be wary of noise
    with some gain on both units you could potentialy get more overall gain and still have good noise floor

    only useful if you are searching for very high gains of 80+ ... distance micing of spoken word or effects sort of thing

    probably not so useful in music record ... even if you do have quiet ribbon mics

    The Summit providing the gain from mic to line and the 002 as a line input is probably going to give the best results

    hello , thanks for email,

    i try today it ,but i still have this noise, i become crazy
    now i am not sure if this is part little noise generate preamp or what...

    with new setup of cables, the only change is i cant use gain on digi002 ,, what i record is not 100% clear like i did years ago with digi001,.,,

    i compare what i did with digi001 and compare what record 002 , and is very diferent... no noise,..

    for exemple if i record my flute , and betwen 2 phrases i try to edit and cut for delete my breath, i can hear the diference betwen noise and silence what i edit, this never happen before , with digi001,, ummmmm

    i dont know what i do wrong,,

    help please!!

    OK, take the Summit out of the equation. and see what happens.
    That is... Plug the mic directly into one of the preamps on the Digi002 and record something.
    Is it still noisy?
    If it is, then you should contact Digi Tech Suppoort and see what they say.
    But if the sound is now clean, then your 002 is fine and it might be that the Summit has developed a problem.

    hello , thank you again,

    well if i conect directly mic to into digi002, if i put gain all the way up, is noise, this thing never hapen with 001, i will call to them but, i dont think they can help, months ago i bought mbox2 i have the same problem, i send my mbox2 to suport and they say this noise is normal,

    so now my question is, are the same preamps in digi001 and digi002 and mobox2?
    i dont think , digi001 is really clean,

    another question is, now i dont use dat or adat, maybe have somethingh to do with 44 khz? if i record 96 khz is better??

    excusme my ignorance,

    what diferent if i record 96 khz?? i can notice big diference??

    thanks, all the best

    Whoa! Opening a preamp all the way up? Well no wonder you are getting noise. Even a lot of highend units are noisy when opened right up. If your 001 was silent I'm amazed!
    If you need to turn a preamp up that far, then either your source is way too quiet, or there is something else very wrong in your signal chain.

    Recording at 96khz won't solve any noise issues. You may hear a slightly more detailed recording, but unless you are recording classical, or your music is ending up on DVD Audio, then I don't think it's worth the extra disk space needed.
    Most pro studios I know who are 192khz capable still record bands at 24/44.1

    hello, yes! is really silence digi001, maybe somethingh wrong but for works really good,

    maybe i am becomimg crazy, and this noise is natural, this noise i appear when i puit headphones all way up, i think normal people dont notice,

    so you think plug reduction noise can solvet this noise???

    i check waves, sound insteresting,,

    all the best, and thanks!

    You still haven't explained why you need to turn everything up flat-out.
    It doesn't make sense.
    I very rarely need to turn anything up over half way.

    kori Guest

    hello, thanks again for ripley

    yes i am agree with you, i dont need put all the way up,

    You should not be getting any noise when recording at normal levels.
    I think you need to get you stuff checked out.
