ADAT - usable?

    hi guys. in the great scheme of things to get for my studio, i've come to the conclusion the pro tools rig should come last, as otherwise it'll be obsolete by the time i open. in the mean time i would like to use my imac g4 and 002. not ideal, i know, but i'm hoping with the right mics and pres i can get truely pro results on this setup for my own projects. the problem i'm having at the moment is the converters. the 002 uses either ADAT or S/PDIF, and as S/PDIF is only 2 channels, that leaves my options relatively unattractive. i've not used ADAT connections before, but have heard they aren't so good. what i'd like to know is whether i'm going to end up with jitter, or severe latency, or any other problems that stop me getting the most out of my quality mics and pres. if there were no sound quality problems i could maybe deal with the latency.

    is the S/PDIF going to be way more usable for overdubs? the converter i've been looking at (apogee ad16x) has no S/PDIF, but will no doubt be the best thing for the job in the distant future when i've get an obsolete pro tools hd rig and ancient g5 for a couple of hundred bucks on ebay. what should i do!?!?

    don't worry about using the ADAT in/outs.... they're fine....

    i would use an RME converter instead of the apogee..... but that's just my taste......

    and remeber to clock protools to the converter....

    thanks for the reply. is the rme recomendation based on sound or price (or the combination of both we seem to call value)?

    i compared the rme to the rosetta 800(with and without bigben)..... liked the rme better

    interesting. which model rme was it? and does anyone know how the rosetta 800 and ad16x compare?

    this one.....


    if you only need 44/48 this one is better


    i think that the apogee's (all of them actually) boost the highs and lows in an unnatural way..... and for some reason the apogee sounded lower in volume although the rme was 0.2dB lower!! (1kHz test tone)

    everything sounded more natural and less hyped(rme)....

    the singer that was present at the test was amazed...

    Longer plastic optical cables can induce jitter ....

    The best thing is to use the shortest and best quality optical cables you can.

    There is a way to convert the ADAT optical signal to a glass fiber optical format for extreemly long runs but if you can keep your cables down to shorter that 4 feet, there should be no issues whatsoever.

    FYI: I use three 15ft optical for 24-channels on a regular basis with Apogee and find I don't need to worry about jitter.
