Digital Sound Projection Technology
Precisely Focused Beams of Sound
Although it is one component, there are actually
40 small drivers and 2 woofers inside. The delay time
of each driver is controlled by a Digital Sound
Processing circuit, enabling the system to project
“beams” of sound which are precisely aimed for
optimum surround sound
effect. Naturally, high quality
two-channel (stereo) sound can
also be reproduced, as well as
three-channel sound if desired.
Beam Mode Selection
Five-Beam: All five
channels—L , R, C, Ls and
Rs—are given separate
orientations. Sound is
beamed off the walls to
create the effect of a
surround system with rear
speakers. Stereo: The left
and right woofers, with
the multiple beam
speakers acting as
tweeters, reproduce the
effect of conventional
stereo speakers. Stereo +
Three-Beam: The L and R
channels are produced
using stereo mode while C,
Ls and Rs are produced
using beaming. This mode
is effective when the
YSP-1 placed in a corner.
Three-Beam: Three beams
are produced: L+ Ls, R+ Rs
and C. A surround sound
effect is created by
reflecting the sound off
the walls.
Precise Calibration Produces Accurate
Multi-Channel Sound
You input a variety of parameters (once only)
to obtain the correct surround sound field.
First, you select room size (large, medium or
small), room shape (square or rectangular) and
speaker position (wall or corner). You can also
make fine adjustments with precise distances
from the listening position. Test tones are
provided to adjust beam angles via the remote
control for maximum surround effect. If you
will be moving the YSP-1, there are three
memory locations for storing different groups
of settings.

The YSP-1 applies sophisticated Digital Sound Projection
Technology to precisely control the orientation of the sound by
focusing it into beams. The result is true 5.1-channel surround
sound without the need for extra speakers! With 42 digital
amplifiers driving 40 1-5/8” full-range drivers and two 4-3/8”
woofers, the Digital Sound Projector delivers 120W of total power
with dynamic bass response.
Multiple channels (two channels in the figure) are superimposed to
create the sound. In a 5.1-channel configuration, the beam
speakers together create the sound of 5.1 superimposed channels.
Sound is projected at the
listener from five directions:
straight ahead, reflected off one
wall, and reflected off two walls
(so it is heard from the rear).

Even if the YSP-1 cannot
be positioned flat against
the front wall (leaving
“dead” space), the quality
of the surround sound
will not be affected.
If the room has an alcove
or other irregularity, the
settings can be adjusted
to compensate, so the
surround enjoyment can
be assured.
