Theta Digital Showcases Unrivalled David II DVD/CD Transport

New Audio And Video Circuits Employ Latest Advances In DVD Technology To Enhance Processing And Performance

5-Feb-01

Theta Digital, long acclaimed as one of the worldís leading manufacturers of digital audio and video products, showcased the David II DVD/CD Transport, successor to the outstanding original David, at the 2001 International Consumer Electronics Show.The David II represents the pinnacle of DVD/CD transport design, providing unparalleled performance and significant evolutionary improvements. Newly designed audio and video circuits set even higher performance standards by taking advantage of the latest developments in fundamental DVD technology. For example, the David II can accommodate digital audio with sampling rates of 44.1, 48 and 96kHz as well as resolutions of 16, 20 and 24 bits. Equally important, the video and audio sections are completely independent and isolated from each other, preventing any interference between them. In essence, the David II includes an audiophile CD transport and a separate videophile DVD transport that share the same chassis. Individual low-jitter crystal oscillators are used for the audio and video frequencies. This allows the signals to be processed independently, dramatically reducing the digital noise that can compromise both sound and picture. To further enhance performance quality, data is buffered and re-clocked, timing errors are corrected using Thetaís proprietary anti-jitter software and all inherent noise associated with each circuit is isolated and filtered.David II utilizes an advanced drive mechanism with dual lasers - 650nm for DVD and 780nm for CD, CD-R, CD-RW and Video CD. This enables the David II to automatically select the correct laser for the type of disc being played. Special low-jitter servo circuits control the motor speed, laser tracking and focus, while sophisticated parametric statistical analysis is used to correct errors caused by fingerprints, dust and disc warping.Digital video signals are converted to analog and sent to Theta-designed filters and high speed output buffers, which provide stunning picture quality. Images are clear, perfectly color-balanced and almost palpable in their dimensionality. The audio side is equally remarkable Through the newly designed audio output section, David II delivers dramatic soundstaging, pinpoint imaging and an extremely wide dynamic range. The result is unrivaled sound quality from both movie and music sources.Thetaís design further enhances the isolation of its circuits by utilizing multiple analog power supplies, including six low-flux Theta-designed transformers and 16 highly filtered and regulated supplies. Each supply has its own integral RF-suppression filter, which reduces the interaction between the stages in each circuit and between the audio and video sections.The David IIís complete complement of video outputs includes one component (Y/Cr/Cb on BNC connectors), two S-Video and two composite (RCA and BNC). On the audio side, the David II provides digital outputs for PCM only (RCA) and PCM/DTSÆ Digital Surroundô/DolbyÆ Digital (RCA, BNC, XLR). An optical output (AT&T or Laser Linque) is available as an option. Also available as an option is Thetaís UltraSync progressive scan output (480p) in both component and RGB with sync outputs for sync on green, horizontal, vertical and composite. Users can also add a 4:2:2 digital video output to service an outboard video processor with digital inputs. This keeps the signal in the digital domain and prevents the inevitable degradation that occurs during multiple conversions from digital to analog and back again. This option will especially enhance the picture quality on flat panel plasma screens and digital video projectors, which perform best when fed a pure digital signal.The David II is available now at a suggested price of $5,000 in stylish platinum or ebony.For additional information about Theta Digital, visit www.thetadigital.com.
