Theta Digital Showcases David II DVD/CD Transport

21-Sep-00

Theta Digital showcased the David II DVD/CD transport, successor to the original David, at CEDIA EXPO 2000. The David II features newly-designed audio and video circuits, and can accommodate digital audio with sampling rates of 44.1, 48, and 96kHz as well as resolutions of 16, 20, and 24 bits. The video and audio sections are said to be completely independent and isolated from each other. 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. Theta says that data is buffered and re-clocked, timing errors are corrected using their proprietary anti-jitter software, and that all inherent noise associated with each circuit is isolated and filtered.The David II utilizes dual lasers - 650nm for DVD and 780nm for CD, CD-R, CD-RW and Video CD. The transport features special low-jitter servo circuits to control the motor speed, laser tracking, and focus, along with parametric statistical analysis to correct errors caused by fingerprints, dust and disc warping.The David II uses 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 reportedly reduces the interaction between the stages in each circuit and between the audio and video sections.The David IIís complement of video outputs includes one component (BNC connectors), two S-Video and two composite (RCA and BNC). On the audio side, David II provides digital outputs for PCM (coaxial) and PCM/DTSÆ Digital Surroundô/DolbyÆ Digital (coaxial, 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 option can 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 platinum or ebony finish.
