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-A1XV, DVD-3800BD and other digital

disc players have received high acclaim. For the DVD-A1UD flagship, Denon devel-

oped the Advanced S.V.H. Mechanism to achieve improved vibration resistance and

quieter operation. The quiet disc loading mechanism ensures the stability demand-

ed 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 centre of gravity for the disc

mechanism and a construction highly resistant to internal vibration caused by disc

rotation and external vibration.

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 fac-

tors. 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 dis-

crete 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.
