This connector is always active, and normally carries the outputs of Channels 1 to 8, enabling the Clarett+ OctoPre to be used as a stand-alone 8-channel analogue mic pre. In ADAT > LINE mode, the connector carries the signals applied at the OPTICAL IN ports [19].
3. If you do have an account, log in and select 4. Select your Clarett+ device from the Product drop-down list and enter the Serial Number of your device at the bottom of the page. The serial number of your Clarett+ OctoPre can be found on the Set Serial Number underside of the unit.
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.
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.
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.
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.
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.
4 . CLARETT+ OCTOPRE WITH ANALOGUE MIXING DESK Analogue Mixing Desk This setup uses the Clarett+ OctoPre’s mic preamplifiers and AIR mode to provide a high quality “front end” for an analogue mixing desk. Use an 8-way loom to connect the OctoPre’s LINE OUT socket to eight line inputs on the mixing desk;...
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.
