Hello group. Had a minor question regarding the BBD individual outputs. Is the raw output fom each tap a result or sum of the settings from each of the two output mixes

For example if the setting on the 396 tap on output 1 mix is +2 and on output 2 mix is +3 the does the individual output of the 396 tap carry the sum of those two settings
If this is indeed the case would equal positive and negative settings at the same tap achieve no signal

Sorry if this over explains the matter, I had a little difficulty articulating this.

Thanks for any help in understanding this.
