Signal level of a specific frequency is
low
❍ Could the EQ gain be turned down excessively?
❍ Routing a signal through a GEQ or effect will delay it relative to other signals. If this signal is mixed with
the signal via a different signal path, a comb filtering effect will cause the level of a specific frequency
to be decreased.

❍ Could there be a problem with the cable that connects the LS9 and external head amp? Are you using
