sockets. Connect further line level signals here using ¼” TRS (balanced) or TS (unbalanced)
jack plugs.
2. LINE OUTPUTS 1 to 4 – four balanced analogue line outputs on ¼” jack sockets; use TRS jacks
for a balanced connection or TS jacks for unbalanced. Line Outputs 1 and 2 will generally be
used for driving the main L and R speakers of your monitoring system, while Outputs 3 and 4
can be used for connecting additional line level equipment (e.g., outboard FX processors). The
signals routed to all the outputs may be defined in Focusrite Control.

6. SPDIF IN and OUT – two RCA sockets carrying two-channel digital audio signals in or out of
the Clarett 4Pre USB in S/PDIF format. Like all the other inputs and outputs, the routing of
S/PDIF signals may be customised in Focusrite Control. The S/PDIF Input appears in Focusrite
Control as Inputs 9 and 10 and the S/PDIF Output as Outputs 7 and 8.
