Prism Sound ADA-8XR Multi-channel A/D D/A Converter

8.10.2 Analogue to DSD Performance

As the Analogue Line Input Module, see Section 3 of this reference, except for the following:
Maximum output level: 0dB SACD (Normal) / +3.1dB SACD (Hot)
Absolute gain accuracy: ±0.1dB
THD+n (997Hz, -1dBFS): -106dB (0.0007%)
Dynamic range (997Hz, -60dBFS): 114dB
Frequency response:
-0.05dB: 10Hz...50kHz
-3dB: <1Hz...70kHz

8.10.3 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=192kHz, -3dB: 0Hz...50.0kHz (HF roll-off compliant with SACD standard)
fs=176.4kHz, -3dB: 0Hz...50.0kHz (HF roll-off compliant with SACD standard)
fs=96kHz, -3dB: 0Hz...41kHz
fs=88.2kHz, -3dB: 0Hz...38.5kHz
fs=48kHz, -1dB: 0Hz...22kHz
fs=44.1kHz, -0.05dB: 0Hz...20kHz
fs=32kHz, -0.05dB: 0Hz...14.5kHz

8.10.4 (PCM to) DSD to Analogue Performance

The following DSD to Analogue specifications are measured using an ADA-8XR Path in PCM
to DSD mode as the signal source (since no standard DSD test source is available). They are
as the Analogue Line Output Module, see Section 4 of this reference, except for the following:
Maximum input level: 0dB SACD (Normal) / +3.1dB SACD (Hot)
Absolute gain accuracy: ±0.1dB
THD+n (997Hz, -1dBFs): <-101dB (0.001%)
Dynamic range (997Hz, -60dBFS): >109dB
Frequency response:
-0.05dB: 10Hz...35kHz
-3dB: 1.4Hz...50kHz (HF roll-off compliant with SACD standard)
