ANALOG CHARACTERISTICS

(Test conditions (unless otherwise specified): Input test signal is a 997 Hz sine wave at 0 dBFS; measurement
bandwidth is 10 Hz to 20 kHz; test load R

L

= 10 pF.)

Notes:

1. One-half LSB of triangular PDF dither is added to data.
2. Performance limited by 16-bit quantization noise.
3. DSD performance may be limited by the source recording. 0 dB-SACD = 50% modulation index.
