Using .The .Optical .Connections .To .Provide .Additional .Inputs - Focusrite Clarett 8PreX User Manual

3. .Using .the .optical .connections .to .provide .additional .inputs

In .addition .to .the .eight .analogue .inputs, .the .Clarett .8PreX .has .two .ADAT .input .ports .(OPTICAL IN) .
which .can .each .provide .an .additional .8 .audio .inputs .at .44.1/48 .kHz .sample .rate, .four .at .88.2/96 .kHz .
or .two .at .176.4/192 .kHz. .Using .one .or .two .8-channel .microphone .preamplifiers .equipped .with .ADAT .
outputs . – . such . as . a . pair . of . Focusrite . OctoPre . MkIIs . – . provides . a . simple . and . excellent . method . of .
expanding .the .Clarett .8PreX's .input .capability.

and Focusrite Control
In .the .example, .the .OPTICAL OUT .ports .of .the .OctoPre .MkIIs .are .connected .to .the .Clarett .8PreX's .
OPTICAL IN .ports .with .two .TOSLINK .optical .cables. .Although .mic .inputs .are .shown .in .the .diagram, .
this .would .allow .any .combination .of .up .to .24 .mic .or .line .inputs, .of .which .some .could .be .INST .level .
signals.
Stable .word .clock .synchronisation .may .be .achieved .by .setting .one .OctoPre .MkII .as .the .sync .master .
and .the .Clarett .8PreX's .sync .source .as .ADAT. .The .second .OctoPre .MkII .can .then .be .synchronised .by .
connecting .its .WORD CLOCK IN .to .the .WORD CLOCK OUT .of .the .Clarett .8PreX .with .a .BNC .cable. .
NOTE: .when .interconnecting .two .digital .devices .by .any .method, .always .ensure .that .both .are .set .to .
use .the .same .sample .rate. .
The .additional .inputs .realised .by .use .of .the .optical .ports .may .be .routed .using .Focusrite .Control .in .
exactly .the .same .manner .as .the .other .inputs. .The .additional .inputs .can .form .part .of .any .musician's .
headphone .mix, .as .required.
