Magnepan CCR - Manual (Page 9)

are often placed in less-than-ideal acoustical environments, exactly duplicating
the left/right Maggies is not possible unless the same acoustical rules are
followed as the left/right speakers.
To make a final adjustment of the center channel bass and midbass level, turn
the volume of the center up or down. This may seem confusing, but, it works
like this-- If you turn the overall level of the center channel up, the center
channel bass will be reduced. To increase the center channel bass, it is
necessary to LOWER the overall center channel level. You may wonder how
that is possible. Well, it is a quirk of how the bass management is structured.
Many consumers turn the center volume up because they have trouble hearing
the dialog, the net effect is less center channel bass/midbass.
You have control over 3 parameters to create the illusion of a large Maggie in
the middle--
1) Crossover point.
2) Level setting with respect to the left/right speakers.
3) Phase. You will need to remember all three as you fine-tune your CCR.
We have had a number of reports that the automatic equalization systems built
into some processors have had less-than-desirable results with Magneplanars.
We are investigating this further, but, apparently the equalization systems are
not compatible with our recommended hookup procedure. We recommend
that you defeat the automatic EQ system and manually make any needed
frequency adjustments.
