2 . Using the optical connections
In addition to two analogue inputs, the 2Pre has an ADAT input port (OPTICAL IN) which
can provide eight additional 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 Clarett
OctoPre – provides a simple method of expanding the 2Pre’s input capability.

and Focusrite Control
The Clarett OctoPre’s OPTICAL OUT port is connected to the 2Pre’s OPTICAL IN port with a
single TOSLINK optical cable. The two devices must be synchronised to ensure audio passes cleanly,
without clicks and pops. To do this in
Focusrite Control
go to
Device Settings
and set the

to
ADAT
. Both devices must be set to the same sample rate.
You can route the additional ADAT inputs in the same way as other inputs in Focusrite Control. The
ADAT inputs can form part of any musician’s headphone mix, as needed.
