Working With Surround Sound - Focusrite Scarlett 18i20 User Manual

Working with surround sound

Because the Scarlett 18i20 is equipped with ten line outputs, it is ideally suited for use when
working in multichannel sound formats – LCRS, 5.1 surround or 7.1 surround, for example. Scarlett
MixControl's Monitor section is pre-configured for several multichannel formats, and resetting the
monitor routing can be achieved with a few mouse clicks.
The example below shows how you would connect the six loudspeakers in a 5.1 surround monitoring
arrangement.
