I'm recording a concert tonight with a rented ST350. Usually, I don't check the ST350 before actual set-up, but this time I did. Probably because the girlfriend was out of town and I could set-up in the living room... and wanted to check out recording at 192 kHz.
Anyway, the test revealed the the W output is going bad: at least 20 dB down in output compared to what it should be. I didn't even listen to it as a change of cables didn't alleviate the problem. So I decided the use the stereo output for the W by setting it to omni pattern and 0 degree width in L/R mode. Connecting to the Left/Mid output, the signal had the right amplitude, but there was some ground-buzz noise it the signal. The Right/Side output is free from the noise, so I'll use that one. I noticed though that decoding to stereo was weird: left and right were flipped and the stereo pair was pointing in the back of the ST350. Close visual inspection of some impulsive waveforms revealed that the "new" W polarity is inverted compared to XYZ. The question is then: which output as the right polarity (going positive on high pressure)? From what I can see in the waveforms, I'd say the B-Format output, but does somebody here knows for sure? In the meantime, for monitoring purposes, I made a VST plug-in that inverts the W and applies the -3 dB.
