■ 

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.

■ 

Crosstalk @1kHz
