Electrical Characteristics

Measured at DIGITAL OUT. Output impedance of signal generator: 150

Ω.

Frequency Response

fs=44.1kHz or 48kHz @20Hz–20kHz, with reference to –1dBFs @1kHz

fs=88.2kHz or 96kHz@20Hz-40kHz, with reference to –1dBFs @1kHz

Gain Error @1kHz

Total Harmonic Distortion

fs=44.1kHz or 48kHz

fs=88.2kHz or 96kHz

Hum & Noise

fs=44.1kHz, 48kHz, 88.2kHz or 96kHz

* Hum & Noise are measured with an A-weighting filter.

EIN Measured with DA824 EIN=Equivalent Input Noise

* EIN is measured with a 6 dB/octave filter @12.7 kHz; equivalent to a 20 kHz filter with infinite dB/octave attenuation.

Dynamic Range

* Dynamic Range is measured with an A-weighting filter.
