A and C Weighted Measurements (optional)
The AC-10 in-line weighting filter provides A- or C- weighting to the microphone
input of the SA-3052A. Without the AC-10, the SA-3052A’s measurements are unweight-
ed. The AC-10 uses active filters to create the two weighting curves. Power for the filter
is supplied by the phantom power supply on the microphone input of the SA-3052A.
