The . front . panel . includes . all . the . input . gain . and . monitoring . controls . as . well . as . two . of . the . input .
connectors .for .Mic, .Line .and .Instrument .signals.
1. . INPUTS .1 .& .2 .– .“Combo .XLR” .input .sockets .for .each .channel .- .connect .microphones, .instruments . .
(e.g., .guitar), .or .line .level .signals .via .XLR .or .¼” .jacks .as .appropriate. .Either .TRS .(balanced) .or .
TS .(unbalanced) .jack .plugs .can .be .used .for .instruments .or .line .level .signals. .
2. . 48V .– .two .switches .enabling .48 .V .phantom .power .at .the .XLR .contacts .of .the .Combi .connectors .
for .mic .inputs .1 .and .2 .respectively. .The .switches .each .have .an .associated .red .LED .indicating .
that .phantom .power .is .selected.
3. . Gain .1 .and .2 .– .two .rotary .controls: .adjust .the .input .gain .for .the .signals .at .Inputs .1 .and .2 .
respectively. .The .gain .controls .have .concentric .bi-colour .LED .‘halos’ .to .confirm .signal .level: .
green .indicates .an .input .level .of .at .least .-24 .dBFS .(i.e., .‘signal .present’), .the .ring .then .turns .
red .when .signal .level .reaches .0 .dBFS. .
4. . INST .– .two .red .LEDs .which .illuminate .when .INST .mode .is .selected .for .the .jack .contacts .of .
Inputs .1 .or .2 .from .Focusrite .Control .software. .When .INST .is .selected, .the .gain .range .and .input .
impedance .are .altered .(relative .to .LINE), .and .the .input .is .made .unbalanced. .This .optimises .
it .for .the .direct .connection .of .instruments .via .a .2-pole .(TS) .jack .plug. .When .INST .is .off, .the .
inputs .are .suitable .for .the .connection .of .line .level .signals. .Line .level .signals .may .be .connected .
either .in .balanced .form .via .a .3-pole .(TRS) .jack .or .unbalanced, .via .a .2-pole .(TS) .jack.
5. . AIR . – . two . yellow . LEDs . which . illuminate . when . the . AIR . function . is . selected . for . each . input .
from .Focusrite .Control. .AIR .modifies .the .frequency .response .of .the .input .stage .to .model .the .
classic, .transformer-based .Focusrite .ISA .mic .preamps.
6. .
.(Thunderbolt .active) .– .a .green .LED .which .illuminates .when .the .unit .has .established .a .
connection .with .the .computer .to .which .it .is .connected.
7. .
.(Locked) .– .a .green .LED .which .confirms .clock .synchronisation, .either .to .the .Clarett .8Pre’s .
internal .clock .or .to .an .external .digital .input.
8. . 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 .four .analogue .outputs.
9. .
.(Headphones) .– .connect .a .pair .of .stereo .headphones .at .the .¼” . .TRS .jack .socket .below .
the .control. .The .headphone .output .always .carries .the .signals .currently .routed .to .analogue .
outputs .3 .and .4 .(as .a .stereo .pair) .in .Focusrite .Control.
10. . POWER .– .green .LED .confirming .that .DC .power .is .connected.
