multi-channel surround sound enjoyment from a single component...

The Digital Sound Projector employs multiple small speakers, each with it's own digital amplifier, and our unique projection technology to control the orientation of the sound. By focusing the sound into ”beams” and controlling the speaker delay times, the listener perceives the sounds to be coming from additional speakers placed throughout the room, when in fact there is only the Yamaha Digital Sound Projector.

projecting/reflecting sound beams

The time delay of each speaker driver is controlled by a Digital Sound Projection circuit, enabling the system to project "beams" of sound which are precisely aimed for optimum surround sound effect. The direct and reflected sound waves produce true multi-channel surround sound.
High separation two-channel sound can also be reproduced by superimposing multiple beams of sound as pictured here.
