Typical Audio Specifications

                   
Sound input using the sound input port:
                   
Input impedance (preamp off ): more than 80 kilohm (ký)
                   
Maximum input voltage (preamp off ): 1 Volt ( V rms) = 2.8 Volts
                   
peak-to-peak ( V pp) ,nominal
                   
Input impedance (preamp on): more than 5 ký
                   
Maximum input voltage (preamp on): 62 millivolts (mV rms ) = 175
                   
mV pp , nominal
                   
Sound output using the sound output port:
                   
Output impedance: 33 ý, nominal
                   
Maximum output voltage: 0.94 V rms = 2.65 V pp
                   
Noise, Distortion, and Bandwidth:
                   
Sound input signal-to-noise ratio (SNR): 85 decibels (dB)
                   
unweighted (add +8 dB to estimate A weighting)
                   
Total harmonic distortion: 0.05%
                   
Bandwidth: 20 Hz ­ 20 kHz at 44.1-kHz sample rate (Other
                   
sample rates scale the upper cut off frequency.)
