Yes. If you are sending one cable, just set up as stereo linked (not dual mono) and pick a side (L or R). If you setup as dual mono (to use the other channel for monitors, etc) the same applies.
The signal in (mono or stereo) will be the signal out (mono or stereo).
... so in dual mono (maybe in all configurations) ... the anti-feedback treats the left side completely independently from the right side ??
... another way to state it: When feedback from a microphone (presumed connected mixer to PA+ with stereo cords) comes from the speaker on the left only - maybe the mic' is closest to that side - then the PA+ only notches the EQ on that left side - the right remains unaltered (EQ &/or level wise, and assuming there is no feedback from that side).

Stereo:
All modules (features) are common. What you do to one side is done to the other, pre or post x-over.
Dual mono:
GEQ is separate. The signals are separate, but the other modules have common control.
