Using The Adat Connection - Focusrite Scarlett 18i8 User Manual

Using the ADAT connection

In addition to the eight analogue inputs, the Scarlett 18i8 has an optical ADAT input port which can
provide an additional eight audio inputs at 44.1/48 kHz sample rate or four at 88.2/96 kHz. Using a
separate 8-channel microphone preamplifier equipped with an ADAT output – such as the Focusrite
OctoPre MkII – provides a simple and excellent method of expanding the Scarlett 18i8's input
capability.

The OctoPre MkII's ADAT output is connected to the Scarlett 18i8's ADAT input with a single TOSLINK
optical cable. To synchronise the word clocks of the two devices, set the word clock source of the
OctoPre MkII to "Internal" and that of the Scarlett 18i8 to ADAT".
Insert Tip symbol When interconnecting two digital devices by any method, always ensure that both
are set to the same sample rate.
The additional inputs realised by use of the ADAT port may be routed using Scarlett MixControl in
exactly the same manner as the other inputs. The additional inputs can form part of any musician's
headphone mix, as required.
