No problem. I might be able to get a plot up today.
I would like some confirmation as well, if it is every card out there.
Perhaps someone with some raw cards could see if those two points are connected on theirs,
If we think it though we can probably check from the top of the card, without having to take things apart.
A simple resistance test will show it. Those two points need to be connected.
I have serviced hundreds of N*v-e modules over the last 15 years. I know what they are supposed to sound like, in all modes of operation, and condition. The first audio test of these lasted 2 seconds, because I knew something was wrong. I make a point of listening before testing.
1.8dB down below 500Hz as a shelf is highly audible. Setup a comparison test, as I have previously outlined, and you will hear it, if it is there. Trust your ears.
I located a missing connection that exactly coordinated with the symptom.
When I installed the connection, the symptom went away, and the performance returned to correct N*v-e specification, in all modes. That would suggest a correct methodology and result.
Unless this has been caught in a board rev, or I got two bad boards (very unlikely) it is safe to say they all do it.
Switching bands off cleans up the sound. It is just good practice. So I always start out that way. That is why I noticed it immediately.
That is why N*v-e's don't use center detent pots. Center is never center on detents, so use a normal pot, and switch the EQ band off if you are not using it.
