DVD-9000 TENTATIVE
High-end DVD A/V Player with 14-bit, 108 MHz Video D/A Converter and PureProgressive Circuit
Denon engineers have pulled out all the stops in its development of the DVD-9000 to ensure that this DVD player reproduces
sound and pictures at the highest possible level of quality. The DVD-9000 is packed with PureProgressive circuitry for superior
Interlaced-to-Progressive video conversion; two 14-bit, 108-MHz video D/A converters, Noise Shaving Video and a Super Sub
Alias Filter. For high-quality audio output, the DVD-9000 sports AL24 Processing Plus supporting a sampling frequency of 192
kHz; a 24-bit, 192-kHz audio D/A converters and other state-of-the-art audio technologies to extract the maximum potential of
DVD-Audio. Along with Denon's critically acclaimed circuit design and chassis construction, the DVD-9000 is a truly remarkable
