2 . Using the optical connections
In addition to eight analogue inputs, the 8Pre has an ADAT input port (OPTICAL IN) 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 Clarett OctoPre – provides a simple and excellent method of expanding the 8Pre’s
input capability.

The Clarett OctoPre’s OPTICAL OUT port is connected to the 8Pre’s OPTICAL IN port with a
single TOSLINK optical cable. Stable word clock synchronisation may be achieved by connecting the
8Pre’s WORD CLOCK output to the Clarett OctoPre’s WORD CLOCK IN and setting the Clarett
OctoPre to use this as its sync source. Alternatively, the 8Pre may be set to synchronise
via the ADAT format signal at the OPTICAL IN port. To do this in
Focusrite Control
go to
Device
Settings
and set
Clock Source
to
ADAT
.
NOTE: when connecting two digital devices by any method, always ensure both are set to use the
same sample rate.
You can route additional ADAT inputs in the same way as other inputs in
Focusrite Control
. ADAT
inputs can form part of any musician’s headphone mix, as needed.
If a suitable D-to-A converter with an ADAT input is available, the OPTICAL OUT port 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.
