Computer requirements

Windows XP, Windows Vista or Windows 7.(Windows XP needs to be fully updated via Windows Update).
The CPU needs to be SSE/SSE2 capable. Most recent CPUs meet this requirement. To check for this capability download this program and run it. There are so many different CPUs the only way to check if yours is powerful enough is to download Sonos 4 and try it. As a guideline a dual core 2GHz CPU is recommended. The amount of memory is not critical.1-2GB is sufficient.


Sound card

A 192kHz sample rate sound card is needed to use the built in stereo multiplex and RDS encoders. Use of a 'pro' sound card with balanced inputs and outputs is recommended  to minimize noise pick up. Some possible choices for a 192kHz sound card are the M-Audio Audiophile 192, ESI Juli@, EMU 0404 (USB or PCI version).

If you need to interface Sonos 4 to other audio applications this can be achieved with Virtual Audio Cables.
