Mpc X main output louder then other outputs.

Hi all,
I just purchased a new analog mixer and i plug all the 8 outputs .
Main output all way to right, direct/main knob also all way to right.
I notice that the 2 main outputs are more louder than the other 6.
I thought it was the opposite .
I also trying different cable and different mixer in.

What i'm doing wrong?
Thanks

isn't the MAIN out more hi-fi than the others?
by a few db, look into manual/specs

I read everywhere that the 3/8 outputs are always at max level
