What is a Digital Sound Projector?
A typical surround sound playback system uses 5 to 7 speakers. To
configure a surround sound playback system that enables audio
playback in the vertical direction, 2 or more additional speakers
should also be installed above the listening position.
A highly realistic sound field can be created with multiple speakers
installed around the listening position as shown in the illustration
above. However, this can be difficult to do in a living room. The unit
utilizes “digital sound projector” technology, enabling it alone to
provide a realistic and engaging surround sound experience.
A digital sound projector provides optimal control over the delay time
for each of the compact speakers installed in orderly rows, and
drives the amplifier for each of these speakers, synthesizing audio
signals output from each speaker as highly focused sounds (sound
beams).
These focused sounds possess wave-like characteristics. When they
hit a hard wall or ceiling, they are reflected off the wall or ceiling. A
digital sound projector outputs sound beams from seven channels,
including front (left/right), center, surround (left/right), and height (left/
right) channels, by reflecting these beams off the walls and ceiling so
that sounds reach the listener from the appropriate direction. It
features a technology that enables true surround sound without
requiring the installation of speakers behind or to the sides of the
listener, or in the ceiling.
By combining sound beams coming from the front (left/right) and
back (left/right), it can also create two new audio channels for
surround sound playback using 7.1 channels in the horizontal
direction. With this configuration, the new audio channels output
sounds from surround sound channels, while sound beams coming
from behind the listening position (left/right) output sounds from
surround back channels.
