    Apollo Twin Duo with Presonus Firestudio

    Hello, I bought a Twin at the end of last year so I could be mobile/have better preamps. I would like to be able to connect my Firestudio to the Apollo so that I can track drums and others with the combined 10 inputs.

    I've read that I have to make one master and one slave, and that apparently it's not an option for Apollo to be master? I have PreSonus connected to Apollo through SPDIF out, coax cable to a converter box, and that optical into the optical in on the Apollo.

    I made the Clock Source on the PreSonus SPDIF, but it still blinks red when I do that, only stays blue once it's Master.

    I set Digital Input in the UAD Console to ADAT and I see the additional 8 ADAT channels in the Console, but not in ProTools.

    When I set PreSonus as Master and Apollo as slave, though the Apollo was reading mic signal, it was not read in ProTools.

    Help would be appreciated! Beginner to understanding all this ADAT/SPDIF stuff.

    By the way I'm running a MacBook Pro 2015 with High Sierra, and Pro Tools 12. Universal Audio software is up to date. Thanks!

    First, spdif is a 2 channel protocol whereas ADAT is 8. If the interface doesn’t have an ADAT output it won’t do what you want

    Hi jackkilbymusic,

    Welcome to the forum.

    As Drew suggested, use ADAT out from the Firestudio. I am assuming the Firestudio has ADAT out. It is old enough it's not listed at Sweetwater, which was where I looked.

    You will need a TOSLINK optical cable. Remove the little red protective caps from the ends. Run it from the Firestudio's ADAT out to the Apollo's ADAT in. Clock synce will take place between the two units. You should be able to set the clock on each unit to internal, and the Firestudio will show up in Console on the ADAT tracks.

    One thing though, you may need to do some setup in the Firestudio's software to tell it to use the ADAT outs. The reason I mention this is I ran into a similar issue settung up a MOTU 828x to output its 8 channels to ADAT.

    HTH

    Actually, my firestudio is older (maybe 2011) and only has two spdif jacks on the back, one input and one output, and I DON'T have an ADAT out. I don't know what the heck all this ADAT stuff even means so I'm all ears.

    Drew, I'm not a moron, I asked a question about why I can't make my Apollo a master and make the presonus firestudio a slave via spdif. If you have help, help. if you're going to post links to read up on things that don't answer my question then I'll take my advice elsewhere.

    Forgive me, I took this to mean you wanted help understanding what ADAT is vs SPDIF.

    SPDIF is a 2 Chanel protocol and won't allow you to get 8 mic pres into your Twin.

    And since the Twin has no digital out, it can't send clock to the Presonus.

    Yes, Apollo Twin must be the slave, since it has no way of outputting clock or digital out where clock could be utilized. What exact Firestudio version is it? Are you trying to use both as a single PT Aggregate Device? This can work, but I've never gotten mixed systems like that to work well.

    If S/PDIF is all you have to work with then aggregate device is the only option.

    Apollo would be S/PDIF and clock would be digital in. Firestudio would be Master/internal clock. Both will need to manually match the same samplerate, most likely.

    75ohm S/PDIF cable is needed. Most regular RCA cables will not work.

    Is it this one?
    https://www.presonus.com/products/FireStudio

    If so, that has ADAT out and you can use UC to route the mic pres directly to ADAT out that can feed the Twin (ADAT, not S/PDIF settings would be set on both).

    ADAT is an 8-channel protocol created by Alesis to let us connect together several of their Alesis Digital Audio Tape recorders. These things each recorded 8-tracks of audio onto a Sony Betamax video tape cassette. With ADAT we could record 24 independent tracks, by connection 3 ADAT recorders together without investing in a 2-inch machine.

    Alesis used a TOSLINK cable for its 8-tracks, and called it a LightPipe instead of using the TOSLINK for S/PDIF, as it was intended by Sony/Phillips.

    It became a convenient standard for sending 8-channels, whereas S/PDIF has only 2 channels.

    Need some help in understanding why I may not be getting this to function properly. I have a Apollo UAD2 8 channel that I need more external mic preamps.

    I have a Presonus firestudio 2626 unit that I want to use as that external device. I have linked the two units together with the optical cables via ADAT ports out of Presonus into Apollo.

    In the UAD console I have set the clocking to be ADAT and I get a green link light for the clock on Apollo. I assume everything should be talking at this point. I'm struggling to get the data channels to turn green
    on the UAd console. If I plug a mic into the presonus how do I get the Apollo to recognize those inputs. I have checked that the rate is 44.1 on both units.

    I think I'm close but obviously missing something obvious?
