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. PCM to DSD Performance Maximum output level 0dB SACD (Normal) / +3.1dB SACD (Hot) Absolute gain accuracy +0.05dB THD+N (997Hz, -1dBFS) -118dB (0.00013%) Dynamic range (997Hz, -60dBFS) 120dB Frequency response: fs=96kHz -3dB: 0Hz…43.5kHz Frequency response: fs=88.2kHz -3dB: 0Hz…40kHz Frequency response: fs=48kHz -1dB: 0Hz…22kHz Frequency response: fs=44.1kHz -0.05dB: 0Hz…20kHz Frequency response: fs=32kHz -0.05dB: 0Hz…14.5kHz Analogue to DSD Performance As the Analogue Line Input Module except for the following: Maximum output level 0dB SACD (Normal) / +3.1dB SACD (Hot) Absolute gain accuracy ±0.1dB THD+N (997Hz, -1dBFS) -103dB (0.0007%) Dynamic range (997Hz, -60dBFS) 110dB Frequency response -0.05dB: 10Hz…35kHz -3dB: 3.9Hz…42kHz DSD to PCM Performance Maximum input level 0dB SACD (Normal) / +3.1dB SACD (Hot) Absolute gain accuracy -0.05dB THD+N (997Hz, -1dBFs) <-126dB (0.0005%, limited by DSD input signal) Dynamic range (997Hz, -60dBFS) >128dB (limited by DSD input signal) Frequency response: fs=96kHz -3dB: 0Hz…41kHz Frequency response: fs=88.2kHz -3dB: 0Hz…38.5kHz Frequency response: fs=48kHz -1dB: 0Hz…22kHz Frequency response: fs=44.1kHz -0.05dB: 0Hz…20kHz Frequency response: fs=32kHz -0.05dB: 0Hz…14.5kHz (PCM to) DSD to Analogue Performance The following DSD to Analogue specifications are measured using an ADA-8 Path in PCM to DSD mode as the signal source (since no standard DSD test source is available).
