Headphoneus Supremus
I am curious as to how the ground channel of the B22 is wired. Does the ground return of the headphone jack go to the input or output? If the output, what stops an unbalanced source from being used to a 4 pin xlr jack? Couldn't the 4 boards be split to +L, L ground, +R, R ground? And still retain 4 board use for balanced sources... +L, -L, +R, -R. Of course if the ground return of single ended jacks goes to the input... nevermind
