waves can be caught and neutralized by draperies, carpeting,
upholstered furniture and gangs of indolent Persian cats...
while gigantic bass waves simply slosh back and forth in the
room.
Another set of variables is the shape and volume of your
listening room. Large rooms require more bass energy to
excite waves within them. Small rooms need less energy, but
reflect it differently. And then there’s the fact that most rooms
don’t have four walls anymore, but open into dining rooms,
lofts, cathedral ceilings, etc. All of this means that predicting
sound interaction patterns is very difficult due to the irregu-
larities of the room shape.
As you can see, room acoustics is an important but com-
plicated subject To learn more about room acoustics, get a
copy of AudioControl’s Technical Paper 107, “Small Room
Acoustics De-Mythologized”. You can download this paper
from www.audiocontrol.com. The overall point that we’re try-
ing to make is that the various rooms in your home function
as gigantic mechanical equalizers, boosting or cutting certain
frequencies depending on size, shape, volume, acoustic treat-
ment and the position of the speakers.
Audio Analysis Using Pink Noise
It may take several series of adjustments since there is
some interaction between each control. We have included
some sample settings and general descriptions of each con-
trol’s function further in this manual.
After initial adjustment the only time you would change
the control settings are 1) if you connect different speakers
into the system, 2) if (assuming the speakers aren’t built-in)
you move them significantly, such as from a bookshelf to floor
stands, or 3) if your room acoustics change through rear-
rangement of furniture, wall or floor coverings, large hairy
dogs, etc.
The following are examples of typical settings along
with short descriptions of each Architect Model 210 Speaker
Optimizer control. Naturally, the results of adjustments will
vary depending on the individual acoustic environment, the
type of speakers, and the personal preferences of the listener.
These recommendations are not concrete, they are simply
good starting points.
