For connecting to PC/Mac computers.
Note: For Class 2 USB audio, Windows-based PCs require a Cambridge Audio USB driver to be installed before connection.
Ground Switch
Note: The ground switch position should be set to 1 as default. Use another position if a humming noise occurs.
Position 1 – Normal/default position. The main unit audio ground is lifted from chassis earth.
Position 2 – USB Audio ground is lifted from the main unit audio ground, which is also lifted from chassis earth. This may be useful to reduce hum
and noise that can occur with some USB Audio setups.
Position 3 – Main unit audio ground is connected directly to chassis ground and USB Audio ground. For some setups, this can reduce hum or noise
when certain TVs, Turntables, and other equipment are connected to the Evo unit.

otherwise is supported.
