Audyssey MultEQ XT32 Software Installation
Referring to Audyssey’s calibration guide, your installer will use a professional calibration microphone
and a digital audio interface with his laptop computer to analyze your room’s acoustic properties as they
affect the entire seating area. This will give him the information to properly set up the volume levels and
delays for each speaker, and then it will automatically generate a series of correction filters to load into
your Phase Technology DP4000 amplifier/speaker controller. This correction process will then return your
speakers to their original perfectly matched levels, and remove the room’s harmful acoustic contribu-
tions, leaving you with superb sonic performance that sounds the same at every seat in the room.
Speaker Placement
Phase Technology’s ability to precisely match each speaker to one another yields a much more envelop-
ing and accurate soundfield. This immersive entertainment experience will be enhanced if you will follow
a few basic rules of speaker placement. The front speakers (left, center, right) should all be placed in as
close to a horizontal line as possible, and should be at or slightly above ear level while seated. The left
and right speakers should be far enough apart (6- 8 feet if seated no more then 12 feet from your video
display) to separate the information from each channel, but not so far as to create a discontinuity with
the image on the video display. With a large projection screen, they should be placed as close to the
sides of the screen as is practical. In addition to being in line with the front channels, the center speaker
should be as close to the center of the display as possible, whether above/below the display, or behind a
perforated projection screen. Phase Technology speakers are magnetically shielded so they will not inter-
fere with any type of television set. Please place the included rubber feet on the bottom corners of each
speaker to keep it from vibrating against the shelf or stand on which it sits.
Each of the dARTS speakers (except for subwoofers) includes Phase Technology’s acclaimed variable-
axis soft dome tweeters. This allows your installer to direct high frequencies toward your listening loca-
tion for even greater latitude in speaker placement, and more precise imaging and localization of sound.
Please adjust these tweeters by carefully pressing on the outer rim of the housing only, avoiding contact
with the actual soft dome speaker element. These adjustments, if needed, should be done prior to your
installer calibrating the system to your room, so the correction process will read the tweeters’ energy ac-
curately at each listening position.
The surround speakers should be placed well above ear level in most rooms. Whether you are using di-
rect- radiating speakers or our switchable dipolar/bipolar speakers for the surround channels, please pay
attention to placing them to create a large and enveloping soundfield. In a 5.1-channel configuration, you
will use one pair of surround speakers. If your listening area is near the back wall, the best results can of-
ten be obtained by placing the surround speakers on the side walls, centered on your listening positions.
With speakers directly to the sides, switching the surround speakers into “Dipole” mode (with their front-
panel toggle switch) will a very diffuse, non-directional soundfield. If you prefer to have more localization
of the surround effects, select the “Bipole” mode or use direct-radiating speakers to match the front
channels. If your seating is away from the back wall, you can choose to mount your surround channels
either beside or behind the listening position. Experiment with both “Dipole” and “Bipole” surround set-
tings with your installer to see which sounds best to you, so he can calibrate the room to your taste.
