Focusrite 18i20 ADAT/Optical Tutorial Faster

My first video about this was kinda bad-- this one clears more info quickly!

Took me a moment to realize that the follower ("slave") device needs to be hooked up via usb for it to be recognized by mixcontrol for setup -- haha... of course it does. Pointing it out for folks who are following step by step.

Saved for future reference. I found this video once and then for some reason could never find it again when I really needed it for a session.

Short and complete. This is how a "How to do" should look like. You helped me to solve that problem. Thump Up! Thanks, man.

Thank you for this video. You got me running! One thing I noticed is you have to have both devices set to dual adat in focusrite control. Otherwise, the mapping of the inputs/outputs gets all screwy. This is with using 2 scarlet 18i20s. Thank you again for making this video!

[TroyTackett]

Sorry for the extra post I just noticed on my new software from focusrite I do not see the dual Aadat option

hi, do you know if I could have two octopre with one 18i20? like this : Octopre 2 > octopre 1 > 18i20 ? Thank you

I've been looking for this solution for too long. Thank you!

This is an excellent tutorial. Make sure to double check your ADAT connection. I couldn't figure out why I didn't get sound from the slave. Well, I didn't plug the cable in the input of the master, so that didn't work.

Actually, it would be best to utilize two opticals for in/out with the BNC for the WORDCLOCK setting the Main interface as that master (internal clock). In this configuration, you can take advantage of both inputs and full outputs (16 in/out). Otherwise, your configuration will NOT allow outputs from your slave (ADAT).

So with my main interface off my focusrite control is not seeing the octopre. Because it is connected to my 18i20. I got the ADAT out and connected even the world clock with a locked connection. However, my DAW is not seeing the extra 8 channels from my octopre. It drove me crazy for hours last night.

How can I connect Samsung Smart Optical Audio to my Focusrite?

[mikadrum]

Thank you so much Shawn, it helped me a lot to setting up my interfaces!

[OneCrimeTV]

How do you make sure the slave interface is the only one on? It connects to the PC... If you turn it off, the ADAT interface doesn't work.

[johnnyhov]

Thanks for a great guide! Guess it is not possible to route PC-sound from audio interface to the OctoPre over SPDIF since there is no SPDIF input on the unit? I only hear instruments etc that is connected with XLR.

This was so helpful for me in setting up my Clarett Plus 8 Pre with my RME BAbyfacePro FS. Thanks a bunch.

I leant one great thing from the comments here. If you have a standard octopre you cannot loop back any outboard hardware units to the ADAT outputs you HAVE to get the octopre Dynamic. Took me 2 weeks to figure out. Wish I could thank whoever wrote that in the comments….hard to find

What buffer size do you use when recording at 44.1kHz? Would you recommend recording at 48kHz if only using one ADAT cable?

My interface is Behringer UMC1820 - which is full. I got a couple of new desktop synths yesterday and bought the Behringer ADA8200 to allow them to be connected. They are connected to ADAT1&2 and 3&4. The ADA8200 is the slave and connected to the UMC1820 by Toslink cables. Everything appears correct. The synths receive midi and the interface receives audio from them - I can see the green leds flash! However there is no audible output! If I connect these synths to the UMC 1820 all is as it should be. Just no audio output when connected via the ADA8200. Latest drivers installed in the UMC1820. I have a feeling it's probably something very simple I'm missing - but it's driving me mad. Any and all help appreciated. Thanks!

Looks like I'm using the same configuration that you're showing: 18i20 3rd gen and 18i20 2nd gen. Is there a reason you're using the 2nd gen as the master instead of the 3rd gen? I set mine up with the newer 3rd gen as the master. The only other difference is I have dual TOS cables. My units were working perfectly together until last week. The power blinked while the computer was on and after that, the 2nd gen slave unit wouldn't talk to the 3rd gen master unit. I thought I had been smart by saving config files for both units but had no joy when I reloaded them. What finally solved my issue was already built into Focusrite Control. While setting up the slave unit, I selected File>Output Presets>Standalone Preamp, converted the outputs from stereo to mono, saved it as backup config, and powered off the unit. I then connected the 3rd gen master unit, powered it on, went into Focusrite Control, selected File>Output Presets>Analogue + Digital, converted the outputs from stereo to mono, and turned the slave unit back on. The master unit instantly recognized all the new inputs and I was back in business, so I saved that config file, too. Hooray for presets!!! In retrospect, I think my biggest mistake was not powering down the slave unit and leaving it off until after setting up the master. Thanks for putting this helpful video out!

Can you use the optical out to connect to the optical input of an RMS Raydat PCIE Card?
