If a suitable multi-channel digital-to-analogue converter is available, the 18i20’s OPTICAL OUT ADAT
ports may be used in the opposite manner; for example, additional outputs from the DAW may be
converted into the analogue domain to allow the use of an external hardware mixing console to mix
down a large number of DAW tracks. At 44.1/48 kHz sample rate, the right-hand OPTICAL OUT port
carries Channels 1 to 8, while at 88.2/96 kHz, the right-hand port carries Channels 1 to 4 and the
left-hand port Channels 5 to 8.
Using the Scarlett 18i20 as a stand-alone mixer
The Scarlett 18i20 has the ability to store a mix configuration defined in Focusrite Control within the
hardware. This feature lets you configure it – for example, as an on-stage keyboard mixer – using
your computer, and then upload the configuration to the device itself. Then you can use the Scarlett
18i20 as a simple local mixer as part of your keyboard rig to control the overall mix of multiple
keyboards.
To FOH Mixer
In the example illustrated, three stereo keyboards are connected to the rear panel inputs of the
Scarlett 18i20; Outputs 3 and 4 go to the main PA system. The performer can adjust the gain
for the individual keyboards from the front panel; he/she can also adjust the overall level of the
keyboard mix.
