Direct Mechanical Ground Construction, embodying concepts for thorough vibration resistance The power transformer, itself a source of vibration, has been placed near the ground and immediately above the insulators to allow direct release to the ground and thoroughly prevent the propagation of unwanted vibration or noise. - Hybrid construction (using heterogenous materials) with dual-layer top cover and triple-layer bottom cover suppresses vibration and resonance. - B.M.C. side panels in high-specific-gravity and high-density hybrid construction suppress vibration and resonance. - Cast-iron insulators absorb vibration and release it to the ground. Denon's original Advanced S.V.H. Mechanism, newly developed for low specific gravity, vibration resistance, quiet operation, and high precision Denon disc drive mechanisms in the DVD-5910, DVD-3800BDCI and other digital disc players have received high acclaim. For the DVD-A1UDCI flagship, Denon developed the Advanced S.V.H. Mechanism to achieve improved vibration resistance and quieter operation. The quiet disc loading mechanism ensures the stability demanded by this top-of-the-line model. Furthermore, by positioning the disc mechanism at a low location, it has become possible to achieve a low center of gravity for the disc mechanism and a construction highly resistant to internal vibration caused by disc rotation and external vibration. - Heavy-duty dual-layer steel top cover - Heavy-duty clamper cover - Zinc diecast mechanism case - Steel shaft with specially fabricated surface - Newly-developed floating dampers - Thin aluminium diecast tray 7-block Structure, to thoroughly prevent mutual interference caused by electrical and magnetic factors The 7 blocks made up of the power unit for analog circuits, the power unit for digital circuits, the server section, the digital signal processing section, the video section, the 2-channel audio section, and the multi-channel audio section have been separated to prevent mutual interference from electrical and magnetic factors. This superb separate structure ensures high picture and sound quality. Dynamic Discrete Surround Circuit-HD, achieving high-quality sound The D.D.S.C. is a Denon proprietary circuit configuration that features a discrete arrangement of signal processing circuits for each block, required for audio playback, to realize Denon's ideal for audio components of faithfully reproducing the content producer's original intentions. The best possible high-grade dedicated circuitry has been used for each block to ensure optimum performance. With the advent of Blu-ray, the volume of information is dramatically greater than that of DVD, delivering improvements in quality for both video images and sound. The DDSC-HD is configured of a high-bit audio decoder section, a bus management section, the Advanced AL32 Processing Multi Channel section, and an analog audio section with a 192-kHz, 32-bit D/A converter to reproduce high-quality sound and bring out the superior quality of Blu-ray sound to the maximum extent.

This marked the beginning of "AL" Processing's history of original waveform reproduction technology. "AL" Processing evolved further with the advent of various new digital disc media such as DVD and Super Audio CD. This evolution progressed from AL24 Processing and AL24 PLUS Processing to Advanced AL24 Processing that achieved sampling frequency expansion, where data is interpolated along the time axis in addition to bit expansion. Now with the appearance of Blu-ray, Denon has developed Advanced AL32 Processing that further expands the number of bits from 24 to 32 to maximize the exceptional audio performance of Blu-ray. With distortion-free sonic details, accurate sound localization, and rich low range, Advanced AL32 Processing is able to reproduce the original sound with greater fidelity. In the DVD-A1UDCI, this newly-developed Advanced AL32 Processing is employed for the 2-channel balanced circuit and for 8 channels, resulting in Advanced AL32 Processing Multi Channel, to bring out the true value of this reference-class Blu-ray player.

Since each has been installed in its own independent audio circuit, audio performance has been improved in such areas as S/N ratio, dynamic range, and channel separation. Multi-channel support from Denon's proprietary Compressed Audio Restorer function To reduce data volume, audio compression formats remove signals that are hard for the human ear to hear. Compressed Audio Restorer regenerates the signals that were removed during compression and restores the sound close to its condition prior to compression. This function also corrects the sense of mass in the low range to produce a richer sound during playback. Compressed Audio Restorer now supports multi-channel playback for the first time, delivering an eminently satisfying sound from such audio compression formats as Dolby Digital, DTS, MP3, and WMA. AV Pure Direct (two HDMI output ports) The DVD-A1UDCI is equipped with two HDMI output ports, making it possible to send only the video signal to a projector and only the audio signal (2-channel or multi-channel) to an A/V surround receiver. Greater picture and sound quality is achieved, as mutual interference is physically eliminated.

It also supports LPCM 192-kHz multi-channel (6-channel) output, one of the audio formats of Blu-ray discs . (*3) These features allows users to enjoy the ultimate in multi-channel sound quality. Denon's video circuitry for high picture quality, to produce a richer video image from DVD [REALTA] The DVD-A1UDCI accurately detects moving images at high speed and at the pixel level of detail for both film and video material, and performs precision calculations when scaling SD (480i) resolution images of DVD to HD (1080p) resolution or IP-converting images from interlaced to progressive video. Digital Noise Reduction, effective for both HD and SD content The DVD-A1UDCI has a digital noise reduction (DNR) system that uses digital pro- cessing to remove noise from video signals. This system is effective not only for standard (SD) video from DVD but also for high-resolution (HD) video from Blu-ray. - Block noise in a mosaic pattern can be seen in a portion of the image. - Mosquito noise makes curvatures appear fuzzy. - Random noise makes the image appear coarse. 06 07
