11. ANALOG, S/PDIF, ADAT 1 & ADAT 2 – input meter source LEDs. Indicates the current signal
source for the input meters. Meter source selection is made from Focusrite Control.
12. (Thunderbolt active) – a green LED which illuminates when the unit has established a
connection with the computer to which it is connected.
13. MIDI – a green LED which illuminates when MIDI data is being received at the rear panel
MIDI IN port.
14. – a green LED which confirms clock synchronisation, either to the Clarett 8PreX’s internal
clock or to an external digital input.
15. MONITOR – main monitor output level control – this control will normally control the level
at the main monitor outputs on the rear panel, but can be configured in Focusrite Control to
adjust the level of any of the unit’s ten analogue outputs.
16. DIM and MUTE – two switches controlling the Clarett 8PreX’s monitor outputs; DIM reduces
the output levels by 18 dB, while MUTE turns the outputs off. By default, these switches affect
the main monitor outputs 1 and 2, but they will also affect any analogue outputs that have been
selected for front panel monitor control using Focusrite Control. The switches are internally
illuminated (DIM: yellow, MUTE: red) indicating that the function is selected.
17. Headphones 1 and 2 – connect one or two pairs of stereo headphones at the two ¼” TRS
jack sockets below the controls. The headphone outputs always carry the signals that are
currently routed to analogue outputs 7/8 and 9/10 in Focusrite Control.
18. POWER – AC power switch and LED.
19. Rack ears for mounting the Clarett 8PreX in a standard 19” equipment rack.
