DIGITAL MODULE SPECIFICATIONS

DSD I/O MODULE
Unless otherwise stated, all performance specifications are quoted RMS, A-weighted, bandlimited 20Hz-20kHz, with PCM sampling at 96kHz and wordlength 24 bits, and with DSD lineup normal. Note that quotation of performance using A-weighting filters is not generally the policy of Prism Sound; however, the noise-shaped nature of DSD signals means that A-weighted measurements are more representative of subjective performance than are unweighted measurements.
