Applies to: Scarlett 4i4 3rd Gen

Scarlett 4i4 3rd Gen requires 900mA of power for complete operation. All USB 3.0 and most USB 2.0 ports* are capable of providing this level of current.

As with all Scarlett 3^rd Gen interfaces, the Scarlett 4i4 can be connected to a USB A port (using the supplied USB cable) or a USB C port using a USB C to USB C cable (not supplied). The performance will remain the same regardless of which port you use.

USB type A
