This function is used together with
subwoofers. This is very useful when
you want to adjust the bass sound for
best front stage image. Start at 0 and
turn the control slowly clockwise until
you experience that the bass sound is
coming from the front. If you don’t get
the result you want, also try to phase
reverse the subwoofer connections and
make a new adjustment.
