ADAT questions

    I've never used ADAT so I am clueless. Reason I'm asking is I have two RME ADI-8 QS that are stellar, I love them but I'm not using them now because I replaced these for the Orion 32, which I'm not completely thrilled about in comparison to the sound quality of the QS' but hey, the Orion 32 has 32 ADDA channels and its good enough for jazz.
    I would have to spend $6000 more to get another 16 ADDA of QS' and that isn't going to happen.

    BUT! I could be using one of these QS' for my capture ADDA and another one for my daughters project studio but I don't have the interfaces for them now as I sold my AES EBU card and replaced it for a MADI interface.


    The QS' also have ADAT I/O so what can I do with that?

    What interface and options do I have? I could buy a used HDSPe AIO for around $450. Would I get the same 8 ADDA channels with ADAT ( 44.1 or better? Does ADAT work well?
    What options do I have with these ADI-8 QS converters now? I'd rather be using them over giving them away for a song. No one knows what these are so they aren't selling. Any suggestions?

    Thanks!

    ADAT is only good for 8 channels at 48k or 44.1k. It is a very good format but make sure your cables are quality. I used to use it lots when I ran redundant double ff800 into twin HD24xr.

    Thanks for chiming in John, what interface did you use or would you recommend?

    I use Adat into a presonus lightpipe. I use rme and apogee Convertors via adat. When I record live gigs via adat hd24 I play it into my computer via adat via adat cable. For a while I had some issues because with the video card in my Mac but updates stabilized things eventually.

    The presonus lightpipe is discontinued and when it goes out of date I'll need to get either an RME pci raydat and thunderbolt adapter if that is made by then or an Orion 32. 32 channels is essential to me. Do you have a PCIe slot? The raydat could work.

    Hi Paul, yes, I have PCIe slots available.

    The RME ADI-8 QS interfaces have 2 ADAT ports in each direction, so can go to 8 channels at 96KHz by using S/MUX protocols.

    For PCIe interface boards, you could look at another German product: the Marian Seraph A3, which has 3 ADAT ports supporting S/MUX protocols.

    right: What is "S/MUX"?


    Bos, thanks for chiming in.

    I thought this but wasn't sure after reading so much on ADAT. I've been confused over other interfacing options for these since I got them. Will I still get the low latency?
    Being accustomed to AES EBU ( and now MADI), and understanding this interface will top out at 96k ( which I have no requirement to go beyond anyway) , what should I be expecting ( pros, cons ) introducing S/MUX to my workflow?

    Thanks for the Marian Seraph A3, tip, I get why we want more I/O for them now.

    Marian Seraph A3,, not available in NA.

    Its refreshing to understand S/MUX better. These QS are even cooler now.

    Bos, I need a min of 24 ADDA

    hypothetically,

    if I bought another QS instead of selling these, and sold my Orion32, I would free up some cash for a used QS and an S/MUX interface. Would I get 24 ADDA top performance @ 96k like I have now via S/MUX?

    How solid would the clocking be with S/MUX?

    Duh, you were obviously using the FW off of the FF800. Chaining interfaces to another is so confusing to me.

    Another question which lends itself to my last question about clocking.

    This interface would then do it: http://www.rme-audio.de/en_products_hdspe_raydat.php These are often available at a good used price ( http://www.ebay.ca/itm/like/301097706735?hlpv=1&cond=2&clk_rvr_id=588212030799&item=301097706735&lgeo=1&vectorid=229529 ) so I may be switching gears here is this works out. but...
    I see an optional clock on the RME page which concerns me.

    I have clocked with just the adat called and been fine but it is better using an external clock via bnc connectors.

    Is this a general consensuses about ADAT/ S/MUX?

    Chris,
    ADAT is a very old protocol and on the way out. No one is making these things any longer and support will be waning. Unless you are going to work at 44.1 or 48 k the 48 k limit or the use of kludgy S/MUX that limits channel count to half are reasons. Clocking issues (ADAT clocks automatically through the light pipe) and the expense of and the mess a snarl of light pipe cables creates are other reasons.

    If i were in your position I would be looking at MADI, USB, or Thunderbolt and to a lesser degree Firewire interfaces.

    Sorry to hear you don't care for the Orion ... I had high hopes for that one.

    Thanks for chiming in Kurt!

    I love the Orion but the QS' are a bit smoother and have a more appealing gain management and additional analog connectors that come in handy when you are in that creative magic when every second counts.

    The Orion 32 is excellent with madi. I definitely recommend it. But the rme aid-8 qs are superb. Thus why they cost $3000 for 8 channels

    all my interfaces here use ADAT and i also ran a bank of ADATs in the 90's. they are fine for what they are but i really don't think you will be very happy with them if you don't like the ORION ... maybe you need to just bite the bullet and get the RME's? i don't think you will be satisfied until you do ......

    hmm, that pretty much killed ADAT for me. hehe Clocking is everything. The Orion 32 and MADI is unreal. Never had better. USB was pretty good until I started pushing the tracks and the session got large. MADI, is the thing.

    The QS have an optional MADI card but they are $650 each too. Damn, this stuff is expensive. I should just sell out and go fishing lol. Hard to get music out of my blood.

    We are plagued aren't we.

    I still use ADAT through my HD24 as my primary converter. Lately I have been experimenting with tracking @ 44.1 instead of 48. I think I'm starting to hear the down dither when I mix down to 44.1 for print. Until I can work with higher rates throughout a project I wont really know, but I am searching for that clarity. I think its all about the clock and conversion at this point. If I have less than 8 tracks at a time I am strictly through the ADAT from all analog front end. I have a patchbay setup as ins/outs/ for the HD24 and can use it as my converter, avoiding the digi at all costs. The clock in the Alesis is so much better than the digi one in the 003. And the conversion is more 'musical' for lack of a better description. The Orion is in my future. As is MADI

    I don't use an external clock with my converters. I have found less reliability with external clocks. I am very much in the minority.
