Audient ASP800 w/ Focusrite Clarett 8 Pre X

Hi I just recently acquired an audient asp800 in hopes of expanding my I/O count via adat. It’s to my understanding that if I use just an adat cable I’ll be slaving the Focusrite to the audient? If I am going out of the word clock output on the Focusrite and into the audient word clock input will I be then bypassing the converters on the audient and slaving it to the Focusrite? My plan was to just use the audient for extra pres. This is my first time trying to use multiple units in conjunction (never needed more than 8 inputs) so please be kind.. any help would be greatly appreciated. Thank you!

You won’t be bypassing the converters in the Audient by using Word Clock from the Focusrite, you will be forcing the Audient to sync its converters to the Focusrite’s clock. I don’t know how the clock in the Clarett compares to the Audient, but I would bet they’re pretty close.

Thanks for the quick response! So connecting them via adat and clocking through the audient wouldn’t make much of a difference?

It shouldn’t, it’ll just be slightly more of a hassle to switch sample rates if that’s something you do often.

I am not sure if I really understood your question. Just a few hints:

ADAT is a digital format.
You will use the Audient Micpres and converters, and transfer the digital data via ADAT to your interface (Focusrite).
ADAT data already "contains a clock", it will work (sync) without extra cable.

I went through the exercise of clocking my Audient ASP800 three different ways: as the master clock via ADAT, as the slave clock via ADAT, and as the slave device via Word Clock. There was no visually discernible change in the noise floor with those three options.

I mentioned that fact in an article I wrote last year, down near the end of an article called "Triple Bypass Part-1". It's on my website on the second page of the articles listing.

You're going to want to go from the Word Clock Out on the Clarett, to the Word Clock In on the Audient, and press in the 75 Ohm termination button. (The last device in a wordclock chain should always have termination.) Use a BNC coax cable.

I think this is going to give a little better clock signal than an optical lightpipe cable would, regarding jitter, if I understand correctly.

This is the most straightforward way to wire it with the Clarett as the master interface. That way the Audient should "follow" the Clarett if the sample rate changes.

You will obviously need to use ADAT/lightpipe cables to send your audio from the Audient into the Clarett. Only one if you are working at 44.1 or 48K. You need two cables if you plan to work at 96K. This is called SMUX.

The ADAT channels appear inside Focusrite Control and you can treat them like any other audio source within your mixer and DAW. You have now successfully expanded your interface.

As monkeyxx stated, I like to keep the WORDCLOCK on its own BNC cable, its just easier and supposedly less jitter in the sync. Make the Clarett the Master device

Hey thanks so much for the detailed response! I tried to set it up this way but for some reason I’m not able to connect the audient and the Focusrite properly. No new channels are appearing in the Focusrite Control and I’ve tried switching the source to word clock and it isn’t syncing. Also hit termination on the audient but the only thing I’m getting is white noise through the di of the audient :( any suggestions?

I'm afraid I won't be able to help without being there in the room with you.

Check and re-check all connections, etc. Check all digital settings as well.
