Analog performance specifications are measured using an Audio Precision™System Two™ audio measurement system in the

averaging mode. At 44.1-kHz operation, bandwidth measurement is limited to 20 kHz. At 96 kHz and 192 kHz, bandwidth measurement

is limited to 40 kHz.

(3)

Theoretical performance in DSD modulation index of 100%. Performance is equivalent to the PCM mode.
