Digital Sound Projector

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.

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).

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.

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: 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,

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.

Position

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.

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.
