Applies to: Clarett 2Pre USB and Clarett+ 2Pre only
As of 12th Feb 2018, the Clarett USB 2Pre USB interface can be bus-powered* after updating the firmware to build 1246 via Focusrite Control 2.3.3 or later.
Clarett+ 2Pre is able to be bus-powered from release.
* For the bus power functionality to work, you must be:
- Running macOS 10.13 or above / Windows 10 Creator's Update or above
- Using the supplied USB-C to USB-C cable
- Connecting the Clarett 2Pre USB to one of the following compatible ports;
| USB A | 7.5W USB-C port | 15W USB-C port | Thunderbolt 3 | |
| Mac | No | No | Yes | Yes |
| PC | No | No | Yes | Yes |
Does the USB-C port on my system output 7.5W or 15W?
- Mac – all Macs that have Type C ports will output 15W, except for the one found on the 12” MacBook (this only outputs 7.5W)
- PC – whilst the majority of type C ports will output 15W, the best way to tell is to check with your PC’s manufacturer / USB port manufacturer.
