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.
