Special Design Features
Advanced Room Correction Audyssey MultEQ ® XT is a room equalization solution that calibrates any audio
system so that it can achieve optimum performance for every listener in a large
listening area. MultEQ
® XT captures acoustical information at multiple locations
throughout a listening area in both the time and frequency domains. It uses a
sophisticated clustering algorithm to combine this information so that acousti-
cal problems are accurately analyzed. Based on these measurements, MultEQ
XT calculates an equalization solution that corrects for both time and frequency
response problems in the listening area and also performs a fully automated sur-
round system setup. The result is clear, well-balanced sound for every listener.
Multiple Setup Memories We then went further and provided support for recalling up to three complete
and independent setup calibrations, any of which can be selected as needed.
While a single setup is all that is necessary, having the ability to recall any of
multiple setups can solve some otherwise difficult situations. For example, you
might want to have selectable setups for
• different room conditions (e.g., drapes open vs. closed)
• slightly different target curves (e.g., music vs. gaming)
• various seating arrangements
Only you and your dealer can decide whether you would benefit from taking
advantage of any of these possibilities. Most people obtain everything they need
from a single setup; but having the flexibility to address unusual circumstances
can be invaluable.
Bi- or Tri-amplification People who have wanted to extract the highest performance from their systems
have known for a long time that driving each section of the speaker directly and
separately yields the finest results. Of course, this requires having a dedicated,
active crossover to divide the frequency range appropriately before the power
amplifiers, so that they can then drive the speakers directly.
Biamplification makes use of two channels of amplification to drive different
portions of a single channel. The most common instance of “bi-amping” today
is in home theater applications, wherein a dedicated subwoofer handles the
deepest bass, while the remaining audible range is handled by the various front
and surround speakers. But you can also biamplify a full range loudspeaker,
driving the woofer separately from the drivers that handle the midrange and
treble frequencies.
Logically, you can combine these two approaches, and the result is “triampli-
fication.” A “tri-amped” system uses separate amplification for three audible
ranges. In our case, the three ranges are:
• deepest bass (one or more subwoofers)
• mid-bass (the woofers in the front and surround speakers)
• midrange and treble (the planar magnetic panels)
