Appendix B - Analogue Specification

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%.
