Audio System
------------
* Custom sound circuitry, including stereo generator (digital-to-analog
converter, or DAC)-capable of driving stereo miniplug headphones or audio
equipment-and stereo sampling hardware (analog-to-digital converter, or
ADC) for recording stereo sound
* 16-bit stereo input and output
* Sample rates of 44.1 and 22.05 kilohertz (kHz)
* Input line level: 2 volts peak-to-peak nominal, into 6.5-Kilohm (k¢)
impedance
* Output line level: 2.2 volts peak-to-peak nominal, into 1 k¢ impedance
* Input through output SNR**: >74 decibels (dB) typical
* Bandwidth: 10 Hz-19 kHz (+/- 2 dB) at 44.100 kHz sample rate
* THD+N**: Less than 0.06%; measured 30 Hz-16 kHz with a 2-Vpp sine wave
input
**SNR is signal-to-noise ratio; THD+N is total harmonic distortion plus noise.
