Appendices
All faders are nominal when measured. Output impedance of signal generator: 150 ohms
❏ Frequency Response
Fs = 44.1kHz or 48kHz@20Hz–20kHz, referenced to the nominal output level @1kHz
❏ Gain Error
Fs = 44.1kHz or 48kHz@1kHz
❏ Total Harmonic Distortion
Fs = 44.1kHz or 48kHz
* Total Harmonic Distortion is measured with a 18dB/octave filter @80kHz
❏ Hum & Noise
Fs = 44.1kHz or 48kHz, EIN = Equivalent Input Noise
* Hum & Noise are measured with a 6dB/octave filter @12.7kHz; equivalent to a 20kHz filter with infinite dB/octave attenuation.
❏ Dynamic Range
Fs = 44.1kHz or 48kHz
* Dynamic range is measured with a 6dB/octave filter @12.7kHz; equivalent to a 20kHz filter with infinite dB/octave attenuation.
