Getting started

Before connecting Scarlett 18i6 to your computer, the software must be installed. This will ensure that the correct drivers are used,

thus preventing any unexpected behaviour.

Note on USB hubs

Scarlett 18i6 is a USB 2.0 device and must be connected to a compatible USB 2.0 port. If using a USB hub, it is essential that all other

devices connected to the hub are also USB 2.0 compatible. If any USB 1.0 / 1.1 devices are connected, the hub will be forced to run at

the legacy speed which may prevent the Scarlett 18i6 from working.

Scarlett 18i6 will use a significant amount of USB bandwidth (the amount of data transferred via USB). If connected to a USB hub

other devices connected to the hub may affect the performance of Scarlett 18i6. For example, if using a USB 2.0 hard drive for audio

sample playback (also transferring a large amount of data) this should not be connected to the same USB hub as Scarlett 18i6.

Therefore it is recommended, when possible, to connect Scarlett 18i6 directly to your computer USB port rather than through a USB

hub.

Powering the Scarlett 18i6

You must use the included power supply to use the Scarlett 18i6, it does not power from USB alone. This is because the analogue

and digital circuitry requires more power to run than the USB standard can provide.
