Audio Performance
Default test conditions (unless otherwise stated):
- Source impedance of Test Set: 50Ω
- Input impedance of Test Set: 100kΩ
- Reference frequency: 1kHz
- Reference level: 0dBu
- All unweighted measurements are specified as 22Hz to 22kHz band limited RMS and are expressed in units of dBu.
- The onset of clipping (for headroom measurements) should be taken as 1% THD.
- Measurements taken with Input and Output trim at center position.
- All levels are intended balanced.
Unless otherwise quoted all figures have a tolerance of ±0.5dB or 5%.
