2. .Using .the .optical .connections

In .addition .to .the .two .analogue .inputs, .the .Clarett .2Pre .has .an .ADAT .input .port .(OPTICAL IN) .which .

can .provide .an .additional .eight .audio .inputs .at .44.1/48 .kHz .sample .rate, .four .at .88.2/96 .kHz .or .two .at .

176.4/192 .kHz. .Using .a .separate .8-channel .microphone .preamplifier .equipped .with .an .ADAT .output .

– .such .as .the .Focusrite .OctoPre .MkII .– .provides .a .simple .and .excellent .method .of .expanding .the .

Clarett .2Pre’s .input .capability.

The . OctoPre . MkII’s . OPTICAL  OUT . port . is . connected . to . the . Clarett . 2Pre’s . OPTICAL  IN . port . with .

a . single . TOSLINK . optical . cable. . Stable . ADAT . synchronisation . may . be . achieved . by . setting . the . .

Clarett .2Pre’s .clock .source .(in .Focusrite .Control) .to .be .the .ADAT .format .signal .at .the .OPTICAL IN .

port.

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 .port .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.
