a view to room acoustics

The Digital Sound Projector allows users to set up its acoustics projection via its graphical user interface (GUI) on TV, or the front LCD panel. With the EASY SETUP option, listening environment configuration is based on three parameter settings: ROOM TYPE, ROOM SHAPE, and SPEAKER POSITION. The following diagrams illustrate how these parameters work in relation to one another.

ROOM TYPE: The OSD allows the user to specify the room dimensions and other settings while viewing the TV screen. The fluorescent display on the unit can also be used. W: room width, L: room length, X: speaker position, Y: listening position
ROOM SHAPE: If the ‘sonic image’ reflected off the right and left walls is insufficiently focused or the right/left balance is slightly off, it can be repositioned using a “phantom” effect relative to the sound from the center.
SPEAKER POSITION: The user uses test tones to adjust beam angles etc. via the remote control. The focal length and range of the beam can be set for each channel individually.

IntelliBeam: auto system calibration

Yamaha’s exclusive IntelliBeam feature ensures optimum multi-channel reproduction with accurate image localization. By monitoring the sound with the supplied microphone and analyzing it, IntelliBeam automatically sets the best beam angles and mode, and optimizes the level and frequency response of each beam. This makes initial setup both extremely simple and acoustically perfect. Manual setup is also possible. (Available only on YSP-800/YSP-1000.)

Left: Each sound beam is precisely directed. Center: Total sound beam effect is optimized. Right: Sound is monitored and analyzed, after which frequency response and other parameters are optimized for the room.
