In .the .example, .the .OPTICAL IN 1-8 .ports .of .the .two .OctoPre .MkII .DYNAMICs .are .connected .to .the .
Clarett .8PreX's .OPTICAL OUT .ports .with .two .TOSLINK .optical .cables. .The .additional .outputs .thus .
created .may .be .routed .within .Focusrite .Control .in .exactly .the .same .manner .as .the .other .outputs. .
In .this .situation, .synchronisation .is .achieved .by .setting .the .Clarett .8PreX's .sync .source .to .INT .(thus .

This .means .that .all .synchronisation .is .via .the .optical .links .and .no .additional .cables .are .required.
NOTE: .when .interconnecting .two .digital .devices .by .any .method, .always .ensure .that .both .are .set .to .
use .the .same .sample .rate.
