Cirrus Original Muttchannel Surround. Cirrus Virtual Speaker & Cirrus 3D-Audio. The CS485xx family is procjrammed using the Cirrus proprietary DSP Composer GUI development tooL Processing chalns may be designed using a drag-and-drop interface to place/utilize functionai macro audio DSP primitives. The end resuit is a software image that is down-loaded to the DSP via sשriai host or sriai boot modes.
