Appendices

All faders are nominal when measured. Output impedance of signal generator:150ohms

❏Frequency Response Fs= 44.1 kHz or 48 kHz @20 Hz–20 kHz, referenced to the nominal output level @1 kHz

❏Gain Error Fs= 44.1 kHz or 48 kHz @1 kHz

❏Total Harmonic Distortion Fs= 44.1 kHz or 48 kHz

*Total Harmonic Distortion is measured with a 18 dB/octave filter @80 kHz
❏Hum & Noise Fs= 44.1 kHz or 48 kHz, EIN= Equivalent Input Noise
* Hum & Noise are measured with a 6 dB/octave filter @12.7 kHz; equivalent to a 20 kHz filter with infinite dB/octave attenuation.
