The frequency response of the sound circuits, not including the microphone and speakers, is within plus or minus 1 dB from 4 Hz to 20 kHz.
Total harmonic distortion plus noise (THD+N) as a percentage of full scale for various outputs are shown in Table 3-3 .
Table 3-3 Distortion specifications
Line input | 0.03% |
Line output | 0.03% |
Headphone jack, open circuit | 0.03% |
Headphone jack, 32-ohm headphones, -20 dBFS level |
0.1% |
Headphone jack, 32-ohm headphones, -1.5 dBFS level |
1.0% |
The signal-to-noise ratios (SNR) for various inputs and outputs are shown in Table 3-4 . The values shown are unweighted; values with A weighting would be about 8 dB higher.

Line output | 92 dB |
Headphone jacks | 86 dB |
Line input | 85 dB |
Internal CD | 82 dB |
