NOTES: 12. The Awtd noise measurement with one input selected in the mixer, and all other mixer selections open.
13. The ratio of the rms output level with 1-kHz full-scale input to the rms output level when the LINE_OUT is
muted.
14. The integrated out-of-band noise generated by the DAC, during normal playback with respect to a 1 Vrms
DAC output.
