Prism Sound <strong>ADA</strong>-<strong>8XR</strong> <strong>Multi</strong>-<strong>channel</strong> A/D D/A <strong>Converter</strong> <strong>Operation</strong> <strong>Manual</strong> - Revision 1.00<br />
As can be seen from the plot, the largest spurious component is at –151.65dBFS, which<br />
represents a huge improvement over competitive asynchronous rate converters, whose<br />
imprecise conversions produce large and obtrusive aharmonic distortion components which<br />
have given sample rate converters their characteristic ‘sound’ in the past.<br />
The Prism Sound SSRC is included with the DSD I/O Module, and allows simultaneous rateconversion<br />
of all eight <strong>channel</strong>s between any two PCM sample rates from 32, 44.1, 48, 88.2,<br />
96, 176.4 and 192kHz.<br />
