■Carousel Changer System
In the DVM-4800’s carousel changer system, any of the other 4 discs can be replaced while one of the discs is in play.
■AL24 Processing Plus
The DVM-4800 uses Denon's newly-developed AL24 Processing Plus for the L/R channel D/A converter section to support DVD-Audio's 24-bit, 192- kHz wide dynamic range format as well as stunningly smooth, clear playback from conventional 16-bit CDs. This solid digital audio technology, inherited from Denon's high-end pure audio separate components, ensures you are treated to the best that both DVD-Audio and your existing CDs offer.
■24-bit, 192-kHz D/A Converter for Optimum Sound Quality With DVD-Audio,2-channel playback gives you a maximum sound resolution of 24 bits at 192 kHz, while dynamic 6-channel surround playback is performed at a maximum of 24 bits at 96 kHz.
The DVM-4800 incorporates the latest, highest resolution Digital-to-Analog Converters from Burr-Brown. These newly enhanced PCM-1704 DACs, now support the maximum resolution 24-bit, 192-kHz 2-channel sound that DVD-Audio can offer. For dynamic multi-channel playback, the DVM-4800 uses a suite of 24-bit, 96-kHz D/A converters that ensure you experience the best of surround sound sources.
■Audio Only Mode
The DVM-4800's Audio Only mode, operated by pressing a button on the front panel, turns off the video circuitry so that high-frequency interference from these sections does not disturb the purity of the DVD-Audio signal and high-quality sound can be maintained.
■Bass Management
When playing DVD-Audio programs, the DVM-4800's Bass Management feature distributes all the low-frequency components contained in the Front L/R, Center, and Surround L/R channels to the subwoofer for output to let you enjoy an even more powerful, dynamic sound.
■Progressive Scan
Progressive Scan technology represents a vast improvement over the interlaced scanning method used in TV broadcasts and other conventional applications, as it can process around twice as much video data to produce a sharper, noise-free picture with finer details. High-definition video images are faithfully displayed with optimum naturalness and beauty.
■High-accuracy 12-bit, 54-MHz Video D/A Converter
The DVM-4800 is equipped with a 12-bit, 54-MHz video D/A converter to convert with ease the huge volume of high-grade digital video data into analog signals. This converter allows even the most delicate signals to be faithfully reproduced into the clear, detailed pictures displayed with Progressive Scan technology.
■Super Sub Alias Filter
The DVM-4800 uses a Super Sub Alias Filter for the digital filter to optimize picture quality. This filter achieves attenuation characteristics of -3 dB in the ultra-high frequency band when the horizontal image is 6.25 MHz. Even at 8.25 MHz, the apparent outer limit of DVD-Video, the attentuation characteristic secured is above -60 dB, ensuring an ultra-high picture quality with superior horizontal line resolution.
■4 MB Buffer Memory
This unit is equipped with a 4 MB buffer memory to ensure that both picture and sound are played without interruption when the DVD disc shifts from layer 1 to layer 2, or in the rare event of a pickup dropout.
■Brilliant Black
DVM-4800 can pass below black video via the video outputs for correct monitor setup and optimum picture quality.
■Aspect Ratio Function for Correct Image Displays
When you want to view video images with an aspect ratio of 4:3 on a 16:9 Progressive TV monitor, the DVM-4800's Aspect Ratio function converts the images to the correct aspect ratio so that you can enjoy high-quality Progressive output on your screen. This function also converts 16:9 images for output to 4:3 TV screens.
