Applies To: Scarlett 2nd Generation 6i6, 18i8, & 18i20; Clarett 2Pre, 4Pre, 8Pre, & 8PreX; Red 4Pre & 8Pre

II. Setting Custom Mixes

When first creating a Custom Mix you may find that this window does not populate, though you will see two “+” signs. This button is here to add a hardware input or software outputs to the Custom Mix. When selected all input options will populate in a selectable tab on the right as shown below.



Both Hardware Inputs and Software Outputs can be linked in stereo on this selection tab by selecting the "1-2" option instead of selecting "1" and "2" individually. 

Outputs are primarily used in linked stereo presenting the ‘left’ and ‘right’ of a standard mix. The option of each output being selected separately is mostly used for 5.1 (surround sound) and other routing needs.

Inputs are primarily selected individually to reflect the mono sound source being used to record, though instruments such as keyboards often provide a stereo output in which case it would be standard practice to link the two stereo inputs.

Once you have selected which inputs you intend to route to your selected output, use the faders to assign output volume. This will be set as the output-volume cap for each selected channel, but is worth noting any adjustments made in Focusrite Control will not affect the inputs signal into a DAW.

Above the volume fader is a small horizontal fader, which represents pan. Pan is the balance between left and right, or the stereo placing of the signal.


It is important to remember that in the Scarlett and Clarett range, the headphones will share a physical routing path with a specific line output. In the case of our Clarett 8PreX, Headphone 1 shares a routing path with Line Outputs 7 – 8 and Headphone 2 shares a routing path with Line Outputs 9 – 10. This means whatever is muted, soloed, or adjusted for the Headphones will also reflect in the shared Output.

 Note that the Custom Mix option will not be available once eight (Clarett and Red) or 5 (Scarlett) Custom Mixes have already been assigned.


Creating a Separate Headphone Mix:
Select the Headphone Output and set this to Custom Mix as well. It is important to note that adjusting the volumes in one Custom Mix with not effect those in another.

Let’s assume we have a guitarist plugged into Input 4 who wants to hear everyone else but doesn’t need to hear his/her guitar in the headphones, we would either mute or lower Analog 4 as shown below.


In the opposite situation, if we have a guitarist plugged into Input 4 whom only wants to hear his/herself, instead of muted or lowering all other inputs we would solo Analogue 4 so it is the only source going to the Output.


In both the Device Settings tab and Output Routing tab you can select in the divider to populate the text box and name each input. You will only need to do this once as each name change will reflect in both tabs as shown below.

To un-name a channel once you are done with your session, simply click in the text box and hit delete on your computer keyboard.
