Intellibeam technology allows the user to hear sound beams that are precisely directed and angled for an optimum listening experience in any size room. The included microphone is used by Intellibeam to analyze the sound being emitted and automatically change the angle of sound beam emission. Intellibeam can be set to calibrate the speaker automatically with the information given to it by the microphone or it can be set to be manually calibrated. Manual Intellibeam calibration is only supported in the YSP-800 and YSP-1000 models and it involves using an on-screen display to set the custom dimensions of your room. Once calibrated, Intellibeam will direct the sound to angels that provide for an all around theatre-like experience.
