Onkyo TX-DS555 Owner Manual - Page 5

Introduction Since the TX-DS555 is equipped with front, center, and Surround amplifiers, you can produce Dolby Digital, Dolby Pro Logic, Hall, Live, Arena, and Studio Surround effects. You can enjoy the feeling of a movie theater or concert hall in your own living room. Dolby Digital Dolby Digital is a new-generation digital audio format for multichannel Surround audio. With this digital audio format, you can create a five full-range channel system that is a developed version of the conventional Surround system (left, center, right, and Surround channel). Adding to its five full-range channels, Dolby Digital supports an LFE (low frequency effect) channel, which is used solely for low frequency sounds independent of the other channels. Dolby Digital is sometimes referred to as a "5.1" channel format since this LFE channel is indicated as 0.1. This fully discrete 5.1 channel Dolby Digital can reproduce the sound of a wide and dynamic range, transforming your room into a home theater. Dolby Digital technology is implemented in such media as laser discs, DVDs (digital video discs), CATV (cable television), DBS (direct broadcasting satellite). By using CATV or the proper equipment for the playback of laser discs bearing the Eip.ir;-: trademark, you can recreate in your own living room the feeling of watching a movie in a top-quality theater. DOLBY PRO LOGIC Surround Many motion pictures have been released in 4-channel "Dolby Stereo" sound, with music, dialogue, and panned effects coming from the 3-channel front soundstage, and surround effects and ambience emanating from the sides and rear of the theater. The motion picture masters are used for production of stereo VHS, VHS-Hi-Fi, Beta Hi-Fi, and stereo laser discs that you can buy or rent at your video store. The TX-DS555 incorporates the Digital Dolby Pro Logic Surround Circuit, which is designed to decode the four-channel audience experience found in DOLBY STEREO movies. Dolby Pro Logic Surround is capable of recreating a multidimensional soundstage, but with the increased channel separation it gives a far greater sense of "movement" and sound localization. Just like in the theater, the addition of the active center channel ensures that all audience members hear dialogue coming from its on-screen sources, regardless of seating position. HALL Surround This mode is especially suitable for media that already has a substantial amount of reverb sound, such as classical music, since it simulates the atmosphere of a concert hall. LIVE Surround This mode reproduces the feeling of a live performance. ARENA Surround This mode recreates the mood of listening to a concert in a domed stadium. STUDIO Surround This mode is good for studio recordings that may have few reverb sounds such as pop and jazz. DSP.(Digital Signal Processor The DSP converts the musical signal into digital form and produces reflected sound from the digital signal. This is applied to the musical signal to yield an effect approaching that of a live performance. Ceiling reflections Stage reflections 0fin Direct sound III Wall reflections Wall reflections NOTES: • The concert hall effect is produced from the reflections and reverberations contained in the original recording. These are converted into reflected sound that is reproduced from four directions. Thus, in some cases an unnatural impression can be conveyed if there are too few reflections in the recording or if the effects in the original recording were produced artificially. • The concert hall effect is not merely an artificial reverberation unit, but a sophisticated effect that spreads existing reverberation around. Multi-Room Remote System Using the Multi-Room Remote System equipment, you can operate all components connected to the TX-DS555 from either the main room or the sub-room.
