Audio Performance
Default test conditions (unless otherwise stated):
- Source impedance of Test Set: 40 Ω
- Input impedance of Test Set: 200 kΩ
- Reference frequency: 1 kHz
- Reference level: 0 dBu where 0 dBu = 0.775 V into any load
- Unless specied, all unweighted measurements are specied as 20 Hz to 20 kHz band limited RMS and are expressed in
units of dBu
- The onset of clipping (for headroom measurements) should be taken as 1% THD
- All distortion measurements are specied with a 36 dB/Octave low pass lter at 20 kHz and are expressed as a percentage
- All levels are intended balanced
Unless otherwise quoted all gures have a tolerance of ±0.5 dB or 5%.
