Yamaha DDP-10 Owner's Manual - Page 7

English FEATURES This unit is a sophisticated digital sound processor designed specifically for decoding the Dolby Digital (AC-3). This unit consists of a Dolby Digital (AC-3) Decoder, Yamaha Digital Sound Field Processor and other original Yamaha functions developed using the newest technology to reproduce sources encoded with the Dolby Digital (AC-3) precisely as movie sound creators intended. This unit will lead listeners into a totally new sound experience. This unit is equipped with "6-channel discrete" output terminals for sending multi-channel audio signals of the Dolby Digital (AC-3) individually. Therefore, the audio amplifier or receiver must have "discrete" input terminals to receive the signals from this unit. If your amplifier or receiver can input 5-channel discrete signals only, see page 12. Digital Sound Field Processing This unit incorporates a sophisticated digital sound field processor. The processor allows you to electronically expand and change the shape of the audio sound field from audio and video sources, creating a theater-like experience in your listening room. Dolby Digital (AC-3) The built-in Dolby Digital (AC-3) Decoder leads you into a totally new sound experiences. Dolby Digital (AC-3) is a new generation of multi-channel digital audio technology, or the newest spatial sound processing format developed for 35 mm film-movies by employing a new kind of low bit-rate audio coding. Dolby Digital (AC-3) is a digital surround sound system that provides completely independent multi-channel audio to consumers. In multi-channel form, Dolby Digital (AC-3) provides five full range channels in what is sometimes referred to as a "3/2" configuration: three front channels (left, center and right), plus two surround channels. A sixth bass-only effect channel is also provided for output of LFE (low frequency effect), or low bass effects that are independent of other channels. This channel is counted as 0.1, thus giving rise to the term 5.1 channels in total. Compared to Dolby Pro Logic that is referred to a "3/1" system (left front, center, right front and just one surround channel), Dolby Digital (AC-3) features two surround channels, called stereo or split surrounds, each offering the same full range fidelity as the three front channels. Sound of wide dynamic range reproduced by the five full range channels presents listeners much excitement that has never been experienced before. Precise sound orientation by the discrete digital sound processing expands realism that the original movie possesses. 3
