Right now I’ve got an Audient asp800 plugged in to the ADAT1 of my ADAT card., Focusrite Clarett opto pre 8 into ADAT 2 and a Focusrite 18i20 into ADAT 3 card of the Utrack-24. . I’ve got the sync source set to Adat 1and the clock source set to Digital I/O. I’ve tried using both anaglogue and ADAT for the output source. I’m able to get clean audio if I only have each plugged in one at a time, but not plugged in together. At this point I’m thinking it has to be a clocking problem. It seems like I have to have each unit set to internal clock in order for each to work individually plugged into the Adat card. When they’re all plugged in together I’ve tried every configuration I can think of but I still get an annoying, loud clicking sound along with a clean vocal. What’s up???

I’m responding to myself here, with kind of a question. I’m thinking that this must be a clocking problem, because by them selves both interfaces worked fine, no clicks. I’m confused on ADAT clocking. I understand that there has to be a master clock and the rest are slaves, when I use the BNC in’s and outs, but what about the ADAT. How should I set the clocks on the interfaces when I’m using them with ADAT out into the ADAT card of the Utrack. If I’m setting the software on the Utrack to clock from ADAT1, then wouldn’t the interface, in this case the Audient, wouldn’t it need to be set to Master? Boy am I mixed up on this one. Sorry to be so tedious here. Marc.11th March 2018 at 23:24 #29533
I have to admit, that I got so down, I prayed about this specific problem. Funny, I’d been praying about getting depressed about this issue, but when I finally asked God to help me find the answer, to me it was a minor miracle. As I was praying, I saw a clear picture in my mind of my RME digiface, then I saw toslink wires coming in to the ins from the ADAT outs of my units, and then running the output cables from the RME into the ADAT card. I was thinking, gee, what if I burn something up, but I tried it and it worked. I had to plug the RME with a USB cable into my laptop, but by doing that, I now have a really cool interface showing all the ins and outs, I can adjust the volumes with that software, turn on and off inputs and outputs etc. , just like the software for my Focusrite 18i20. So far so good, and I just have to thank God. I’m still wondering why I had to go all the way to the RME, though. I’m wondering why I couldn’t get it to work without the RME. Still interested in any info you guys might have about that. Marc.17th March 2018 at 20:28 #29564
This is just an update to the ADAT problem post above. I was getting clear audio out of the Utrack using the 3 interfaces plugged into the RME and then out to the Adat card, but I kept getting this bad clicking sound again. After pulling my hair out for a few days, I actually prayed again, and honest to God, I kept seeing a clock setup using daisy chain BNC cables running through all the units. Well, I started by running BNC word clock out of the 18i20, into my Clarette, out of the clarette, into my Audient and terminating the Audient with a 75 ohm termination plug or actually using a built in button to do that on the Audient. Well…………., thank God it worked, but before that I tried splitting the signal just before the Audient and running the other tap up to the Utrack. At that point the Audient wouldn’t lock, so I cut out the t-bar just before the Audient and just ended the chain with the Audient, leaving the Utrack 24 out of the loop. At that point everything locked sync and worked, but……………………., but,….. [i]and now here’s the rest of the story[/i]!! It all worked, but I had so much trouble with the routing software that came with the RME ADAT distribution box, I just pulled the RME box out of the setup and ran Adat out of each interface into the ADAT card on the Utrack. At that point I used the 18i20 as the master clock, and set it that way, then set the other two interfaces to wordclock or “slave” if you will. I set the Utrack to ADAT I/O I believe and used one of the other interfaces for my source ADT. It all works now, and I’m able to send each channel to it’s respective Utrack input, with a clear signal.
If any one has any questions, especially with the Utrack setup, I’ll try and be prudent about answering them. For some reason, using the BNC clock setup was the only way I could stop the insane clicking sound. If anyone has an easier or different way to do it, let me know, so we could all see how to do it. Thank you for your time everyone. I hope this long post can help someone. Marc.19th March 2018 at 13:38 #29569LaszloKeymaster
If you are using different interfaces you need to make sure they are sync to the same clock.
Using the wordclock is the easiest way to do that. You need to select which one is the master device and sync the other devices to this source.
If you want to receive with the uTrack24 you need to make sure the device has pre-recording enabled and the pre-recording successfully started. If all of your ADAT devices synchronized to each other in this case you can even sync to one of the ADAT source or you can sync to wordclock.
The uTrack24 also has a wordclock output which provide the clock where the uTrack24 sync. If you set internal the uTrack24 acts as a master then provide this internal clock on the wordclock output then you can sync your ADAT devices to this.
If you sync the uTrack to wordclock it provide the same clock on the wordclock output, or you can also sync to any of the ADAT clock then you can sync the rest of the ADAT devices to the wordclock output from the uTrack2424th March 2018 at 07:11 #29590
Thank you again, as always, Laszlo. You’re very prompt on these responses. I know that means a lot to all of us who are trying to get things right with our equipment. I totally understand where there only can be one master clock, and everything else has to be a slave to it whether it is in a daisy chain or some other configuration or combination of that, but somehow, it still get’s hazy to me when it comes to the ADAT part of it. Right now I’m clocking my three 8 channel interfaces together with word clock using the Focusrite 18i20 as my master. For some reason I wasn’t able to carry the word clock signal thru to the Utrack 24 without losing sync on my last interface in the daisy chain which would be my Audient. I’m still able though to record and use all 3 interfaces clearly and they seem to be in sync with the Utrack. I do however have the ADAT card on the Utrack which I’m running all 3 interfaces into that with toslink. I also have the I/O on the Utrack set to digital I/O. and I’m syncing to the 3rd interface on my Utrack with the ADAT part of the Utrack. I’m probably not saying that too well but what I’m getting at is even though I think I set everything right using only the ADAT card and setting things to sync from ADAT 3, I still had to hook up the word clock daisy chain in order not to have noise on my recordings, like a bad clicking sound.

Ok, here’s my latest greatest on this whole ADAT card word clock thing. I just purchased a Black Lion micro mkIII word clock that has 6 BNC outputs, and a couple of other outputs including a SPDIF output. I was able, now, to connect the spdif output from the Black Lion into the spdif in of my Focusrite 18i20, and also run individual BNC outputs into each of the two other interfaces and my two Utrack 24 units, using BNC plugs. I’m using 75ohm terminators on both of my utrack clock out’s and I’m also using terminators on my Clarett Opto Pre since it has a clock out BNC plug. That has worked well. Everything say’s it’s clocked ok and of course I’m also running my 3 interfaces into my ADAT card on one of my Utrack-24’s. I’m now able to record on any of my 24 channels, without any noise or clicking sound, everything seems pretty quiet and I’m also able to use my 2nd Utrack as a slave to the master Utrack. I’m waiting to get some more money so I can buy another ADAT card for the 2nd Utrack and then run the slave as a redundant copy machine from the master. I’ll either send 2 toslink signals from each interface into each Utrack machine, or in some cases, split the optical signal coming out of one of the interfaces, and run that into both Utrack machines. So far the Black Lion clock is working well for all of this and I’m very happy with the sound I’m getting from everything. Marc Trainor.27th April 2018 at 00:33 #29702EmilyParticipant
Your solution is really helpful. Thanks a lot!
