    The OctoPre is an ideal “expansion” unit for adding eight more inputs to an existing audio interface such as other members of the Focusrite Clarett range. The Clarett OctoPre is a bidirectional unit: it is also equipped with ADAT format digital inputs and balanced analogue outputs. It incorporates an ADAT-to-LINE mode, making it the perfect interface for routing tracks from your DAW to an analogue mixing console.

    Use the SAMPLE RATE switch [9] to select the desired frequency. It is essential that the sample rate selected on the Clarett OctoPre matches the sample rate set on the transmitting digital device. AIR mode An important feature of all models in the Clarett range is the new design of analogue preamplifier.

    The Clarett 8PreX would normally be the sync master in this situation, so its clock source is set to INTERNAL (via Focusrite Control). The clock source on both Clarett OctoPres is set to ADAT, so both are synchronised to the Clarett 8PreX via the ADAT optical connections.
