By using the setup wizard, cross over output gains and post cross over parametric EQ settings

are set to match your system. The Auto-EQ can be used to adjust your system to compensate

for r

oom effects, and adjust the response of the entire system to your liking. After allowing

Auto EQ to “pink the room” your system will sound tighter. The low end will have more def-

inition, the mids will be more intelligible, and the highs can be tamed. Here are two things to

look for to get the best per

for

mance from the Auto-EQ.

Look out f

or Modes

Some speaker and RTA microphone positions will result in certain frequencies canceling out.

The resulting modes can not be corrected with equalization. The Auto-EQ does not detect

modes in the frequency response, so may try to boost a band to compensate for a mode with
