Applications
There are many applications that can benefit from
the use of Miles Technology's Multisonic
®
Imaging:
Auditoriums and Performing Arts Centers:
The
Multisonic Imaging system makes the often-desired
left/center/right front-of-house system a convenient
reality. Vocal intelligibility is greatly enhanced by the
center channel, and overall music program
subtleties are brought out. Live mixes can be
panned out for full stereo with results far superior to
conventional two-channel systems and even
superior to discrete L/C/R systems. Comb filtering
problems and hot spots are gone. Almost all of the
seats receive excellent, balanced stereo sound.
Sanctuaries:
Multisonic Imaging provides a clear
center channel that improves vocal intelligibility
while also creating a much larger listening area
receiving optimum, full-range sound. When live or
recorded stereo music is played, everyone will hear
the full stereo sound; when one is speaking through
a microphone, the clarity, focus, and intelligibility will
be dramatically improved.
Nightclubs:
Stereo sound is more evenly
distributed over the entire dance floor and audience
area. Overall levels sound more impressive with the
same SPL and with low distortion. Even with a loud,
chest-thumping beat, patrons and employees will
find it more practical to interact.
Foreground Music Systems:
Music is often used
to create an atmosphere at places like record stores
or department stores. The idea is for music to be
heard clearly and yet not be overpowering.
Multisonic imaging achieves this, in addition to
enhancing the drama and subtleties of music with
the benefits of true stereo sound.
Touring Sound Systems:
Multisonic imaging can
be used for large or small touring systems, not only
for effects and stereo playback, but especially as
the primary imaging method for the entire mix. The
vast majority of the audience will hear excellent
stereo localization, and those who are very close to
a particular loudspeaker system will still hear the
entire mix, with sounds panned to the opposite side
slightly down in level but still audible in the mix.
Home Theater Systems:
Multisonic Imaging is
ideal for home theater systems. Any stereo TV
broadcast or videotape will provide outstanding
results, superior to "steered" logic systems.
Multisonic Imaging can image any and all directions
simultaneously (steered systems can localize at
only one direction at a time, resulting in frequent
sound staging compromises). In addition, the
Multisonic system provides superior playback with
all audio program sources.
Portable Sound Systems:
A Multisonic system will
greatly enhance the performance of small portable
systems, increasing coverage area and providing a
"bigger" sound. The low cost and small size of the
Multisonic Imager truly improves the performance
quality of any portable audio setup.
Television and Radio Production:
Quite often,
control and production rooms at broadcast facilities
present a difficult environment for accurate stereo
monitoring of source material. The Multisonic
Imager solves this problem by increasing the
listening area so that several people in the control
room can simultaneously hear the audio with correct
stereo perspective. Any technical problems, such as
loss of stereo or phase errors, will immediately be
audibly obvious.
Recording Studio Monitoring:
Stereo recordings
can be optimally engineered to take full advantage
of the increased clarity provided by the three-
channel Multisonic sound. These enhanced results
can also improve performance with conventional
systems. Also, the increased optimum listening area
of the studio control room will be greatly appreciated
by all those who need to "listen in" during the
mixdown process.
Stereo Processing:
the Multisonic Imager is
generally the best way to implement stereo-to-5.1
format conversion. The Multisonic Imager can also
be used with stereo recordings for vocal
cancellation. And it can restore lost separation in a
stereo recording.
Home Stereo Systems:
Using a Multisonic Imaging
system is the very best way to listen to CD
∗
s, tapes,
broadcasts, or other program sources. Previously
hidden detail in recordings will be heard. The
loudspeakers will sound more at ease with program
dynamics, and the listener no longer needs to sit in
the center of the room to hear good stereo. The
Multisonic Imager effectively converts all stereo
sources to sound as good as or better than discrete
5.1 sources.
Theory Of Operation
The Multisonic
®
Imaging System is based on a
patented linear-matrix audio imaging circuit, which
creates three signals to drive three loudspeakers
from a standard two-channel program source.
The Multisonic Imaging System electrically
separates left, center, and right components, in the
form of three electrical signals, from the left and
right input signals. It then acoustically separates
them by feeding the signals appropriately to three
loudspeakers which are physically and acoustically
located at the appropriate left, center, and right
positions.
