Focusrite Control Knowledge Base: Clarett setup and use with additional mic pre-amps

Focusrite Control – Clarett Setup with additional mic pre-amps using ADAT inputs and outputs

If you are using any one of our Scarlett 2nd Generation 6i6, 18i8 or 18i20 interfaces, Clarett or Red 4 and 8Pre units, then Focusrite Control is your command center for not only getting started but additionally for organizing your work-space, assigning your mixing and routing inputs for all recording scenarios, and finally meeting extended monitoring needs.

Claret 8PRE

With your Clarett 8PRE you can extend you input count using additional microphone pre-amps that consists of their own ADAT inputs & outputs. The concentration here will focus on using the use of the Clarett 8PRE with an additional Microphone Pre-amp that consists of its own ADAT inputs and outputs. You will need to set up both units independently before using them in tandem with one another. The unit that will be used by the host computer as your interface will be referred to as the MAIN device and the second pre-amp in the system to extend your inputs by 8, will be referred to as the ADAT unit to keep things simple.

*Cable type needed to connect both the MAIN and ADAT units will be a Toslink/ADAT cable (pictured below)

MAIN SETUP

In the Device Settings window, start from top to bottom. Its important to make sure SYNC is displayed as in the figure above. This lets you know your host computer and the devices are synchronized together using the Clarett’s clock. The control software version is listed as well; as we see the Clarett 8PRE.

Next, set the desired Sample Rate. Please keep in mind as well that the sample rates must match between the MAIN and ADAT units to keep everything in sync and avoid further errors, which may result in audible distortion.

Optical cables only send information one-way so it’s vital to remember this when choosing your Clock Source settings for both devices. We can run the setup with one or two cables depending on the inputs and outputs offered on the ADAT unit. The Clock Source for the MAIN interface will be set to either “internal” or “ADAT” based on the connectivity to the ADAT device.

With (1) optical cable only, running from the ADAT unit into the Clarett, our Clock Source for the ADAT unit will be set to INTERNAL, and for the Clarett we will want to set to ADAT.

If the Clarett 8PRE is set up with a second optical cable runnig back to the other mic pre-amp via the Optical out to the Second Pre-amp's ADAT In, then we'll set this the Clock Source on the Clarett to INTERNAL and then ADAT on the Second Mic Pre. Once again, this all depends on whether the second mic pre have ADAT inputs.

 

Here's the setup guide depending on the number optical cables you are using between the units:

Focusrite Control setup with use of (1) Optical cable/ Toslink:

Clarett 8PRE (MAIN): Set Clocking: ADAT

Second Microphone Pre-Amp (ADAT)- Set Clocking: INTERNAL

Focusrite Control setup with use of (2) Optical cables/ Toslink:

Clarett 8PRE (MAIN): Set Clocking: INTERNAL

Second Microphone Pre-Amp (ADAT): Set Clocking: ADAT

 

Mixing & Routing Setup

Using the Presets is the fastest way to get the setup in Focusrite Control fast for this scenario. For use with the Clarett 8PRE and a second mic pre-amp, selecting Analog + Digital will automatically configure your Mixing and Routing section populating all of the available inputs for both the MAIN interface and ADAT. The way this setup will display in the Mixing & Routing windows will be as it appears below. As you will notice there is a scroll bar as well which will allow you to pull the other inputs into focus on your display. Focusrite Control's display window can also be stretched vertically and laterally to give you a larger screen based on your host computer's resolution settings.

In the event you're not in need of displaying all of the inputs between the two devices you can disable those inputs from Focusrite Control's Mixer by toggling the (+) tabs which open and close the input sections. The inputs section comes in 2 parts:

MONO
STEREO

The Mixing & Routing section provides for flexibility with setting up your Mixer the way you want it so you don't have to over clutter your work-space.
