In my studio I use some very cheap lousy crappy Pronomic M-802 mixers as 'personal headphone mixers'.
But recently I discovered that one of them had 15 dB(!) less gain from input to output.
Also the level meter indication is lower for the same input level.
Strange enough the gain from input to 'FX out' is the same as the other ones.
So I suspect there is something wrong with the (L/R) summing amplifier.
The whole thing is full of SMD components, so I would need a circuit diagram to find the problem.
I realize that I am asking for the (almost) impossible, but you never know...
Is there a circuit diagram of the Pronomic M-802 mixer around somewhere?
It would be a great help to have it!
(I asked Kirstein in Germany who sells the mixers, but I do not expect very much of it...)
