function of both our unusually sensitive planar magnetic drivers and the small
enclosure volumes behind the woofers. The magnitude of this difference varies
among the different models, and with varying room placement.
The second reason for a difference in overall level between upper and low fre-
quency sections of the speakers is that the amplifier chosen to drive the planars
may or may not have the same input sensitivity as the one used to drive the
woofers.
Determining the trim value The best solution for both situations is the same: measurement the response of
the speaker, both above and below the crossover frequency. Then adjust the
planar magnetic side of the speaker up or down as needed to match the output
of the woofer section. This adjustment can be made on the left side of the
Room Calibration window, in the area labeled “High Crossover Volume Trim.”
(See below. Note that you will see fewer trims if you are using fewer than seven
main channels.)
Room Calibration tab
The SC-1 itself provides a high resolution measurement system, used in the
MultEQ Pro calibration process.
Without getting too far ahead of ourselves (since we have not yet discussed
MultEQ Pro), the idea is to take three measurements of what is happening in
your room, and to look at the resulting response curve. Comparing the average
level above and below the crossover frequency will tell you how much you
need to adjust the planar section up or down. This process “roughs in” the re-
sponse of the system so that MultEQ has less work to do.
The cardinal rule of all equalization is that it is most effective when
it is least needed. Anything you can do to get the system closer to
where you want it to be before Audyssey is asked to fix the rest is a
Good Thing.
