width control fully ACW (as narrow as possible) Then,
whilst listening carefully, slowly turn the NOTCH
Frequency Control CW. Stop turning immediately when
the unwanted noise has been located and removed
All EQ and Parametric EQ in particular, should be used
carefully and sparingly. The use of EQ can improve or
worsen sound quality. Even frequencies that may sound
unpleasant when heard in isolation may need to be
retained as part of the overall mix of a body of sound, to

An alternative view would be that carefully tuned active
EQ boost and cut can be used creatively beyond just
problem solving

through and amplifies the fundamental frequencies and
harmonics above that. Hence "High Pass Filter". This
may be partly countered by turning up Bass or Lo Mid
