Note:

  1. The full-scale level means the highest output level without clipping.
  2. The noise-level means the lowest A-weighted noise level at any volume settings.
  3. The SNR is measured with a -60dBFS sine tone at 997 Hz presenting (AES17).
  4. The THD+N is the average THD+N between 20Hz and 10kHz at 1/3 octave step (AES17).
  5. The frequency response is relative value relative to 997Hz (AES17)
  6. For devices that run at lower than 40kHz sample rate, tests are done only up to near Nyquist instead of 20kHz
