    DB25-to-jack breakout cables are available from professional audio suppliers. DIGITAL OUTPUTS Use the OPTICAL OUT ADAT port(s) [18] to connect the Clarett+ OctoPre to the ADAT input(s) of an audio device using TOSLINK optical cable(s). The ports can send eight channels of audio at 44.1 kHz or 48 kHz sample rate via a single optical cable.
  • Page 10: Digital Synchronisation

    On the OctoPre, SYNC should be set to INTERNAL and the LED will illuminate. An alternative method is to synchronise the receiving device to the Clarett+ OctoPre’s WORD CLOCK OUT using a BNC cable. The receiving device’s sync source will need to be set to its external word clock input.
  • Page 11: Inserts

    INSERTS Each preamplifier channel includes a switchable insert point to connect external processing equipment such as compressors or noise gates. The insert includes a send and a return: with no jack in the INSERT socket, the channel signal path is uninterrupted. The insert send and return are both unbalanced.
  • Page 12: Adat-To-Line Mode

    8 chs. Ch. 8 This mode allows you to use the Clarett+ OctoPre to connect an 8-channel ADAT format output (from a DAW, for example) to a set of analogue inputs. For example, you can send the channels from your DAW to outboard equipment to use as part of your mixing process.
  • Page 13: Example Setups

    OPTICAL MONITOR Here the OPTICAL OUT on the Clarett+ OctoPre is connected to OPTICAL IN on a Focusrite Clarett+ 8Pre audio interface with a single optical cable. Both units are running at 44.1 kHz sample rate. The OctoPre’s clock source is set to INTERNAL, and the 8Pre is synchronised to it because its clock source is set to ADAT (via Focusrite Control).

    Clock set to Internal via RedNet Control This example shows a similar setup as Example 2, but using a Focusrite Red 8Line audio interface running at a sample rate of 96 kHz (“SMUX-II” mode). Both units must be set to 96kHz; you need two optical cables, carrying four channels of audio each.

    The setup in this example would allow you to send 16 DAW tracks to the desk if you only used one Clarett+ OctoPre. The above channel counts are applicable at 44.1/48 kHz sample rate, providing a Focusrite Red 8Line the primary interface.
