Appendix C – Performance Specification

The following pages contain audio performance specification figures for the XLogic E Signature Channel unit. No other Solid State Logic products are covered by this document and the performance of other Solid State Logic products can not be inferred from the data contained herein.

Measurement Conditions

For each set of figures on the following pages, the specific unit and test setup will be stated at the beginning of that section. Any changes to the specified setup for any particular figure(s) will be detailed beside the figures to which that difference applies.

Measurement References

Unless otherwise specified the references used in this specification are as follows:

• Reference frequency:

1kHz

• Reference level:

0dBu, where 0dBu ≈ 0.775V into any load

• Source impedance of Test Set:

50Ω

• Input impedance of Test Set:

100kΩ

•All unweighted measurements are specified as 22Hz to 22kHz band limited RMS and are expressed in units of dBu

•All distortion measurements are specified with a 36dB/Octave low pass filter at 80kHz and are expressed as a percentage

•The onset of clipping (for headroom measurements) should be taken as 1% THD

•Unless otherwise quoted all figures have a tolerance of ±0.5dB or 5%

Microphone Input 1 (Transformer Coupled)

Measurement Conditions
