Digital Cinema Auto Calibration Digital Cinema Auto Calibration was developed by Sony to automatically measure and adjusts the speaker settings to your listening environment in a short period of time. Digital Direct Twin Drive Subwoofer Utilizing Sony's proprietary S-Master technology, the Digital Direct Twin Drive Subwoofer features two S-Master Digital Amplifiers that provide dedicated power to a strategically located subwoofer for astounding sound performance. Easy to set up, Digital Direct Twin Drive Subwoofer provides a stable sound field over a much larger listening area without having to adjust frequency levels. Digital Infrared Audio Transmission Recent times have been witness to the rapid spread of DVDs, Digital Broadcasting Satellite Receiver and other high-quality media. In order to ensure that the subtle nuances endowed by these high-quality media would be transmitted with no accompanying deterioration, Sony developed a technology called "Digital Infrared Audio Transmission" for the infrared transmission of digital audio signals using no compression, and it introduced it into the system. This technology transfers digital audio signals using no compression inside the subcarrier frequency band allocated by the IEC (International Electronic Committee) and JEITA (Japan Electronics and Information Technology Industries Association) for hi-fi audio transmission applications. (See Fig. 1) Analog transmission Digital transmission (Digital infrared Audio Transmission) LR 2 3 4 5 6 [MHz] Fig. 1 Signal spectrum for digital infrared audio transmission Dolby Digital This movie theater sound format is more advanced than Dolby Surround Pro Logic. In this format, the surround speakers output stereo sound with an expanded frequency range, and a subwoofer channel for deep bass is independently provided. This format is also called "5.1" with the subwoofer channel designed as the 0.1 channel (since it functions only when a deep bass effect is needed). All six channels in this format are recorded separately for superior channel separation. Furthermore, since all the signals are processed digitally, less signal degradation occurs. Dolby Pro Logic II Dolby Pro Logic II creates five full-bandwidth output channels from 2 channel sources. This is done using an advanced, high-purity matrix surround decoder that extracts the spatial properties of the original recording without adding any new sounds or tonal colorations. x Movie mode The Movie mode is for use with stereo television shows and all programs encoded in Dolby Surround. The result is enhanced soundfield directionality that approaches the quality of discrete 5.1-channel sound. x Music mode The Music mode is for use with any stereo music recordings, and provides a wide and deep sound space. Dolby Surround Pro Logic As one method of decoding Dolby Surround, Dolby Surround Pro Logic produces four 94US
