During the automatic room calibration process, YPAO R.S.C. with 3D, multipoint and angle measurement analyzes the room acoustics and performs speaker angle measurements. After this, YPAO calibrates all of the audio parameters to achieve optimum sound at any of the listening positions in the theater. It employs Reflected Sound Control to correct early reflections for studio-quality surround sound playback. Additionally, it includes DSP Effect Normalization, which varies with each CINEMA DSP program and adjusts the room acoustics according to the reflected sounds of that CINEMA DSP program.
