I have been measuring with REW the last few days testing some new drivers and I noticed the L(1) & R(2) channel levels are @ 3dB different recently.
REW -> WMD -> MC -> 8-channel DAC -> amps -> speakers
REW is writing to MC's WMD to indirectly access the multi-channel DAC. The hot channel is always the right upstream channel (2), not any of the other channels. If I swap L(1) and R(2) in MC, the left(1) downstream speaker becomes hot.
I thought it might be the convolution filter or the config file, so I tried and old convolution and config file. Same thing.
I then disabled convolution and put a high-pass filter on all 8 channels in MC. Same thing happens when using MC's high-pass functionality instead of convolution including swapping left(1) and right(2). The hot channel follows the R(2) upstream source.
When I pull down the signal path popup, everything looks as expected. I do not see any channels being incremented/decremented by 2/3dB.
Any ideas on how I can debug this further ? Are they any logs that can be dumped and examined ?
Thanks much.
Again, if I swap L&R in MC software panel or at the amp's input, it follows the upstream source.
