Electrical Characteristics
Input Level VR is nominal when measured. Output impedance of signal generator:600ohms
Frequency Response
Fs=48 kHz: @20 Hz-20 kHz, reference to the nominal output level @1 kHz
Fs=96 kHz: @20 Hz-40 kHz, reference to the nominal output level @1 kHz
Gain Error
@1 kHz
*1 In these specifications, when dBu represents are specific voltage, 0 dBu is referenced to 0.775 Vrms.
Total Harmonic Distortion
*1 In these specifications, when dBu represents are specific voltage, 0 dBu is referenced to 0.775 Vrms.
*2 Total Harmonic Distortion is measured with a 18 dB/octave filter @80 kHz.
Hum & Noise
Fs=48/96 kHz
*1 Hum & Noise are measured with a 6 dB/octave filter @12.7 kHz;
equivalent to a 20 kHz filter with infinite dB/octave attenuation.
*2 In these specifications, when dBu represents are specific voltage, 0 dBu is referenced to 0.775 Vrms.
