Hi everyone, I have a quick question about calibrating a Soundfield MKV. At the moment the test tone oscillators are coming in with the W channel about 3.5 dB lower than X,Y, or Z (these three channels are within about 0.5 dB of each other).
So obviously the best thing would be to return the unit to get it calibrated as it's probably due for one; and this has been noted before on this list; http://sursound.music.vt.narkive.com/UtLGYHeC/sursound-level-alignment-of-soundfield-microphones However, my question is, if we know what the gain mismatches are based on the test tone output, is it sufficient to just apply gain adjustments to the b-format recordings based upon these Test Tone signal levels? Or is there a possibility that the test tone channel levels, and microphone channel levels could differ? I would have imagined that both signal paths run through the same circuitry so any gain differences would be present in both (and so can be compensated for), but any thoughts or prior experience with this issue would be much appreciated.
