Connecting your Scarlett 18i20
Power
The Scarlett 18i20 should be connected to AC mains with the supplied AC power cable. Plug the
IEC connector into the rear panel IEC receptacle. When using the Scarlett 18i20 with a computer
(i.e., not as a “stand-alone” mixer), we recommend that the unit is not turned on until the USB
connection has been made – see below.
USB
USB Port Types: The Scarlett 18i20 has a single Type C USB 2.0 port (on the rear panel). Once
the software installation is complete, simply connect the Scarlett 18i20 to your computer; if your
computer has a Type A USB port we recommend you use the Type A-to-Type C USB cable provided
with the unit. If your computer has a Type C USB port, please obtain a Type C-to-Type C cable from
a computer supplier.
USB Standards: Note that because the Scarlett 18i20 is a USB 2.0 device, the USB connection
requires a USB 2.0-compliant port on your computer. It will not operate correctly with USB 1.0/1.1
ports: however, typically a USB 3.0 port will support a USB 2.0 device.
When the USB cable has been connected, turn the Scarlett 18i20 on with the front panel power
switch.
