[. . . ] And it's no coincidence that they're part of Sony ES, the Elevated Standard in audio and video. After all, Sony co-invented the technology that DVD is based upon-- the Compact Disc. We developed the error-correction and coding technology inside every DVD disc and player. And we're involved in every link of the DVD chain, from movie and music production to DVD authoring, mastering and replication. [. . . ] This LSI enables you to apply a carefully timed delay to each individual speaker. Because most people can't make the mental leap from microseconds to speaker distance, Sony calibrates the delay as distance, in 5-cm (2-inch) increments. Each 150 microseconds of delay "moves" a speaker back 5 cm (2 inches). In this way, Speaker Time Alignment adjusts the "virtual position" of each speaker, enabling you to synchronize the arrival time of sound for all five speakers. You can even change the perceived distance of the subwoofer in relation to the other speakers. With Speaker Time Alignment, you'll experience multi-channel sound as it was meant to be heard. You'll get the effect of perfect speaker placement, even if your actual placement is far less than perfect! ES Series DVD-Video/CD/SA-CD Players; Version 3. 0 Page 22 Sony's powerful CXD9722 handles both Speaker Time Alignment and A/V alignment. Incidentally, this adjustment is not duplicated on most A/V receivers. Some receivers can adjust for speaker distance on the multi-channel signals that are decoded in the receiver itself. But most receivers offer no such adjustment for the 5. 1-channel analog inputs you'd be using to enjoy multi-channel Super Audio CD. A/V Alignment (all models) Today's advanced televisions and video projectors often incorporate sophisticated video signal processing to optimize the image quality. Often, these circuits require buffer memories that result in a slight delay of the video signal. Unfortunately, this can result in a mismatch, where the television picture lags behind the sound from the speakers by some fraction of a second. This ensures uniform frequency response and gain characteristics at the output. Sony's careful design not only maintains the sonic purity of multi-channel Super Audio CD signals, but also preserves the crucial left/right and front/rear symmetry of 5. 1 DVD-Video surround signals. On the DVP-NC555ES, a separate printed circuit board for analog audio employs six separate, identical circuits to handle the 5. 1 channels of output. ES Series DVD-Video/CD/SA-CD Players; Version 3. 0 Page 25 Audio Shield Plate (TM PI 2000) The TM PI 2000 prevents even minute interference between the analog video and analog audio circuit boards. The boards are separated by a substantial shield plate that includes a copper sheet to block radiation. This substantial, copper-lined shield plate protects the analog audio board from even subtle distortions caused by the analog video board. Wideband digital outputs (TM PI 2000) To deliver a high quality digital signal, the TM PI 2000 employs a widebandwidth optical module. This offers plenty of headroom for the 4. 6 Megabits per second required by 96 kHz/24-bit outputs. The coaxial output delivers comparable quality thanks to a high-performance pulse transformer. Both digital outputs assure superb dynamics while holding noise and distortion to the bare minimum. Audiophile-grade components (TM PI 2000) Two capacitors with identical circuit values can have quite different sound quality. For this reason, Sony engineers have taken the time to choose topquality audiophile-grade components throughout the TM PI 2000. The op amps, resistors, capacitors and more have been individually selected and matched for their sound quality. For example, carbon resistors with nonmagnetic leads have been chosen for their higher handling capacity. Sony engineers chose a grounded, 3-pin plug for superior mechanical and electrical characteristics. ES Series DVD-Video/CD/SA-CD Players; Version 3. 0 Page 26 Sony's choice of a grounded AC input assures a more stable electrical and mechanical connection. Gold-plated output jacks (all models) To maximize electrical conductivity and minimize the effects of oxidation over time, the audio, composite video, S-Video and component video output jacks are plated with gold. Noise at the contact points is held to a bare minimum. You might not notice that the output jacks are plated with gold. [. . . ] Simple frame memory I/P conversion results in a motion blur every time fields from different film frames are combined. (This occurs for two out of every five video frames--or 40% of the time!) At bottom, full 3-2 reverse conversion, as featured in Sony's progressive scan DVD players, preserves the integrity of the original film frames. ES Series DVD-Video/CD/SA-CD Players; Version 3. 0 Page 49 Appendix B: The Super Audio CD Format Because there's so much more to hear. TM Super Audio CD is the most fundamental improvement in digital music reproduction since the CD itself. It comes from the people who invented the CD: Sony and Philips. Direct Stream DigitalTM encoding Other digital systems--including the very latest designs--use Pulse Code Modulation (PCM). Unfortunately, PCM record/playback systems require decimation and interpolation filters that can cause problems, including requantization noise, passband ripple and ringing. [. . . ]
