The last four shows I recorded, one of the channels is 4-5 dBs below the other, and the kick/bass drum sounds distorted in both channels; is worse in one of the channels.
The first show where I noticed the problem, I used the following rig: MK41s > Actives > BabyNbox > Sony A10
For the last three shows, I've used this rig: MK41Vs > Actives > BabyNbox > Sony A10
To experiment at home, I switched out the A10 for a Roland R-07, and recorded some music off the radio, and the 4-6 dB loss in one channel shows up on the Roland as well. I also tried switching out the Baby Nbox with a Platinum NBox, and get the same 4-6 dB difference.
I suppose it could be an issue with my Active cables or the 3-pin / 1/8" cable that I use to connect my Baby Nbox to the recording deck. I'm not very good with electronics, but wonder if there is there a way to physically check the cables themselves to see if there is an issue with them? I'm guessing, if there is internal damage, it would be hard to tell from just looking at them.
This is really frustrating! Any advice welcome!
