    Hi.

    What is the latency of R.ED? From input to output and/or stereo bus. How does R.ED handles latencies produced by processing??
    How about if you are using some I/Os as inserts, with different latencies??how do you compensate for this??

    Thanks

    Hi Caiv!
    I don't know the technical specs, but the R.Ed. is a dedicated real-time recorder/editor. This means that the problems of latency that normally occur in host-based systems, doesn't apply to the R.Ed. in the same way.
    You can use the mixer as you would do with a hardware equivalent. With real-time processing of effects, monitoring and recording tracks.
    Plug it in and start making music!
    It's really as easy as that...

    Regards,
    Fredrik.

    Hi!!

    Every pice of digital equipment have latency. one way or the other. from a a/d. to a single cable run. now. the amount of latency is another thing. it may be a couple of samples. in pt you have something like 24 samples of latency.. the problem with this is when you combine two identical signals. a few samples may not screw up your audio. but as the latency increases. you start having phase problems specially in your hi frequencies.

    this also apply to hardware.

    You don't need to tell me that twice..

    Cheers

    Hello again!
    Great article. I hear you...I wasn't sure if you were talking about the totally unbearable latency that may occur in a host-based computer DAW.
    As I said, I don't know the numbers, but by using my ears I usually push tracks or insert a sample delay line in the mixer to avoid most of the phasing problems.
    As the article stated, it would be great to have digital equipment reacting/working just as fast as analog.
    What can I say? Life's full of compromises... tongue.gif

    All the best,
    Fredrik.

    Hello claiv, sorry for my delay!

    Any way here we go.


    Minimum Latency through the mixer via digital I/O is less than 16 samples from in to out.
    This is 0.333mS at 48kHz or 0.1666mS at 96kHz.
    Keep in mind that each element you add into the mixer adds 4 samples. So for a topical mixer strip would be a 2 band EQ,Dynamics, and 2 sends, this would add 16 samples delay to the above number.
    Keep in mind, this is with out the Analog converters.

    An AD or DA converter chip has a latency approximately of 25 samples. (to put it in perspective),
    so you can go analog-analog in 66 samples. This is 1.375mS at 48kHz or 0.6875mS at 96kHz.

    Best Regards

    Hello. lemme tell ya.. R.ED looks better now that you answer my questions..

    So..can I mach this latency on the mixer without changing my time line on the arrangement??

    And I guess the answer is yes. one more point for R.ed.

    Hey thanks for taking your time answering this questions...by the way.. is there any way I can get a hold of a manual?? is it available on the net?? it would be nice to be able to gaze at the manual before I come across the "mullah" for the unit..and I have a collection of manuals that I would like to keep current..

    Thank you and cheers
     
  7. Caiv,
    The manual isn't available electronically, but has an SLP of $39.00 in the US (BTW, which particular R.Ed. are you interested in?) If you want to order the manual, call me toll-free at (866)NEIKIRK (634-5475.)
