    What are the specifications for sound input and output for Power Computing machines?

DISCUSSION

    Here are the sound input and output specs for the PowerCurve, PowerCenter, PowerWave, PowerTower, and PowerTower(e).

    16-bit stereo input and output Sample rates of 44.1 and 22.05 kilohertz (kHz)

    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.

    Input line level: 2 volts peak-to-peak nominal, into 6.5-kilohm

    Impedance Output line level: 2.2 volts peak-to-peak nominal, into 1 kilohm impedance Input through output

    SNR*: >74 decibels (dB)

    Typical Bandwidth: 10 HzÜ19 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.

    Machines Affected: PowerCurve, PowerCenter, PowerWave, PowerTower, and PowerTower(e)
