The remainder of the Clarett 8PreX’s inputs and outputs are on the rear panel.
1. MIC INPUTS 1 to 8 – eight balanced mic inputs on 3-pin XLR input sockets - connect
microphones via standard XLR mic cables.
2. LINE INPUTS 1 to 8 – eight balanced line inputs on ¼” jack sockets. Connect line level signals
here; either ¼” TRS (balanced) or TS (unbalanced) jack plugs can be used for line level signals.
3. LINE OUTPUTS 3 to 10 – eight balanced analogue line outputs on ¼” jack sockets; use TRS
jacks for a balanced connection or TS jacks for unbalanced. The signals routed to these
outputs are defined in Focusrite Control, and can typically be used for driving alternative
speakers (i.e., midfield, nearfield, etc.), the additional speakers in a multichannel monitoring
system, or to send audio to outboard FX processors.
4. MONITOR 1 and 2 – two balanced analogue line outputs on ¼” jack sockets; use TRS jacks for
a balanced connection or TS jacks for unbalanced. These are also Line Outputs 1 and 2 of the
system, and will generally be used for driving the main L and R speakers of your monitoring
system. However, the routing of signals to outputs may be customised in Focusrite Control.
5. OPTICAL IN and OUT – four TOSLINK connectors (two inputs and two outputs), each carrying
eight channels (1 to 8 and 9 to 16) of digital audio in ADAT format at 44.1/48 kHz sample rate,
four channels at 88.2/96 kHz or two channels at 176.4/192 kHz. These are simply additional
inputs and outputs (respectively) to/from the Clarett 8PreX. The OPTICAL IN 1-8 connector
may alternatively be configured to receive a two-channel S/PDIF signal from an external
source equipped with an optical S/PDIF output; similarly, the OPTICAL OUT 1-8 connector
may be set to carry the signal routed to S/PDIF OUT in optical format. These options are
selected from Focusrite Control.
6. WORD CLOCK OUT – a BNC connector carrying the Clarett 8PreX’s word clock; this may be
used to synchronise other digital audio equipment forming part of the recording system. The
source of sample clock synchronisation used by the Clarett 8PreX is selected in Focusrite
Control.
7. WORD CLOCK IN – a BNC connector for the connection of an external word clock signal. Use
this input if you have a master reference clock which provides synchronisation for all the
digital audio devices in your studio.
8. – Thunderbolt™ connector; connect the Clarett 8PreX to your computer with a suitable
Thunderbolt™ cable.
