Appendix C – Performance Specification
The following pages contain audio performance specification figures for the XLogic 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%
Channel Microphone Amplifier
Measurement Conditions
Signal applied to Channel Microphone Input (A or B) and measured at Output. Pad switched out and Input Gain
control set to +6dB.
Gain Variable from +6dB to +72dB in 6dB steps
Independently switchable 18dB Pad available
Input Impedance > 1.5kΩ (or 8.45kΩ with HI Z ‘IN’)
Output Headroom > +26dBu at onset of clipping
THD + Noise < 0.003% at 1kHz
(-10dBu applied, +30dB gain) < 0.005% at 10kHz
Frequency Response +0.05dB/-0.1dB from 20Hz to 20kHz
–3dB at 200kHz
Equivalent Input Noise < –127dBu at maximum gain (input terminated with 150Ω)
< –90dBu at 0dB gain (+18dB with Pad ‘IN’)
Common Mode Rejection > 75dB from 50Hz to 1kHz
(-10dBu applied, +30dB gain) > 70dB at 10kHz
