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 room 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 performance from the Auto-EQ.
Look out for 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
