User manual DENON DVD-5000 Product Brochure

[. . . ] The DVD-5000 is further equipped with HDCD decoding that has been combined with Denon's digital technology to bring out the highest quality in sound that is possible with HDCD-encoded CDs. The DVD-5000 passes the strict THX Ultra specifications by Lucasfilm Inc. , that have been established for best possible picture quality, audiophile sound quality and ease of operation. s Newly-developed AL24 Processing s THX Ultra Certified AL24 Processing has inherited the technology of the original ALPHA Processing that was used in Denon's highly-successful S1 series of reference-class audio components. AL24 Processing further reduces quantization distortion and represents the ultimate analog waveform reproduction technology designed to support the higher numbers of bits and higher sampling rate of next-generation media. [. . . ] HDCD uses Peak Extension and Low-level Extension technology to convert 24-bit data to the 16-bit data format of existing CDs without sacrificing the high quality of 24-bit sound. This technology prevents the sound from becoming distorted during peak periods, and boosts the low-level Fig. 1: AL24 Processor Block Diagram Fig. 2: How AL24 Processing Works on Audio Signals A. Data generated at higher-order bits (1-16) D. Data generated at lower-order bits (17-24) signals to improve the S/ N ratio for a substantially richer dynamic range. Since the DVD-5000 is equipped with an HDCD decoder, the Peak Extension and Low-level Extension features are accessed and combined with Denon's own 96 kHz, 24-bit 4-DAC system to fulfill the maximum potential of HDCD's remarkable sound quality. The DVD-5000 also automatically senses the type of disc that has been loaded (ordinary CD, DVD disc, or HDCD), then processes the signals based on the type of disc detected. s s Easy-to-use Graphical User Interface (GUI) s Parts Strictly Selected for Sound Quality Independent D/A Converter s The DVD-5000 can also be used as a D/A converter. The front panel Source switch directs the digital input signals coming in through one of the two digital input terminals (optical or coaxial) so that it passes through the unit's AL24 Processor and D/A converter for output as a clean, highly accurate analog signal. s Three separate transformers have been employed for the audio, video, and control sections. Transformers specially constructed with vibrationresistant materials are used in the audio and video sections. In addition, the same strictly-selected parts whose performance has proven to be reliable during the development of Denon's S1 series of audio components -- such as the removable ultra-thick AC power cord; very low ESR electrolytic capacitors, film capacitors and carbon resistors designed for high sound quality; and the high speed operational amplifiers selected for highest sound quality -- have gone into the DVD-5000. High-performance Pickup and Digital Servo Technology In order to read the maximum 8. 5 gigabytes of data that can be recorded on one side of a DVD, the DVD-5000 uses a self-excited oscillator type red laser with a wavelength of 650nm to ensure stable, low-noise performance. In addition, the pickup lens used with this laser employs an integral molding hologram that enables DVD and CD program sources to be read by the same pickup. As a result, the DVD-5000 features the shortest possible signal paths, a simplified construction and superior reliability. Color Component Video Output The DVD-5000 is equipped with a color component signal video output capability that faithfully outputs the analog signals resulting from direct and high-precision D/A conversion of the Y, Cb and Cr signals recorded on DVD. "S" and composite video outputs are also provided (2 of each). s Vibration-resistant Construction s s s Gold-plated Audio and Video Terminals Digital Theater Systems (DTS) Compatible Digital Output Easy-to-use Remote Control with Backlit Keys The DVD-5000 protects the DVD and the transport mechanism from unwanted vibrations using a centrally located holder with low center of gravity firmly secured with mechanism brackets to the unit's highly rigid, copper-plated chassis. This mechanism is further isolated from the digital, video and audio circuits which have each been mounted on their own copper-plated board so that the circuits can be thoroughly protected from mutual interference and vibrations. The overall chassis of the DVD-5000 is constructed of a 15mm thick aluminum front panel, a double-layered top cover and a quadruple-layered bottom chassis assembly. All these parts have been secured with vibration-absorbent sintered alloy insulators to produce a construction that is totally protected from both internal and external vibrations. ALPHA Processing and AL24 Processing s Expanding to Input Signal Bit Length of 24 Bits While the original ALPHA Processing system generated four lower bits of data for the 16-bit input data to obtain data of 20-bit quality, the new AL24 Processing uses two calculating circuits in its lower data generation section to generate eight bits, to which the upper 16 bits of data is then added, producing an output signal of 24-bit quality (Figure 1). First of all, the data reproduced from a CD is input "as is" in its 16-bit staircase form to the ALPHA processor, as shown in waveform (A) of Fig. [. . . ] COAX.
