Digital Sound Projection Technology

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 4cm full-range drivers and two 11cm

woofers, the Digital Sound Projector delivers 120W of total power

with dynamic bass response.

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.

Speaker Array

Sound is focused

into beams.

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.

YSP-1 Rear Panel

The YSP-1 rear panel offers 2 optical/1 coaxial digital and

2 analogue inputs, subwoofer output and RS-232C interface.

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.

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:

and right woofers, with

the multiple beam

speakers acting as

tweeters, reproduce the

effect of conventional

stereo speakers.

Three-Beam:

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.

Listening

Position

Three-Beam:

are produced: L+ Ls, R+ Rs

and C. A surround sound

effect is created by

reflecting the sound off

the walls.
