DVD-A1UDCI
Denon is Proud to Announce the Completion of its Flagship Home Entertainment System with the World's First Blu-ray Universal Player
State-of-the-art Denon Solutions for Maximizing
Content Quality
The world's first universal player with Blu-ray that also plays Super
Audio CD and DVD-Audio (*1)
The DVD-A1UDCI lets users enjoy not only Blu-ray discs but also Super Audio
CD, DVD-Audio, DVD-Video, and CD discs in the impeccable picture and sound
quality that is expected from a Denon player. The DVD-A1UDCI is also equipped
with DTS Neo:6, Dolby Pro Logic IIx and other decoders that reproduce surround
sound with the best possible quality for the disc's content.
Use of DENON LINK to achieve the world's first jitter-free transmission
of digital audio via HDMI (*1)
DENON LINK is proprietary high-quality digital audio transmission technology that
utilizes a real-time balanced transmission system to protect the signal from external
noise. DENON LINK 3rd achieved DSD transmission of Super Audio CD signals,
earning high praise for the superior quality of digital signal transmission. With the more
advanced DENON LINK 4th used in an HDMI connection, for HD audio read from
Blu-ray disc as well, the master clock that operates the D/A converter of the A/V sur-
round receiver is transmitted to the player, enabling the circuitry to be operated while
sharing the same clock in order to achieve digital audio transmission with negligible
jitter. Sound localization becomes more precise, and a greater sense of space is
produced in the sound images. When combined with a Denon A/V surround receiver
that supports DENON LINK 4th (*2) , users will be able to enjoy the level of sonic quality
that is expected from HD audio.

Block diagram of 2ch full balance transmission
The world's first fully balanced transmission of 2-channel analog sound in a
universal player with Blu-ray (*1)
Fully balanced transmission circuitry for the entire signal path to the output port
has been adopted for the DVD-A1UDCI's dedicated 2-channel analog circuit. When
combined with the AVP-A1HDCI and POA-A1HDCI, fully balanced transmission is
possible from the D/A converter of the player to amplification of the power amplifier.
The balanced circuit is resistant to noise, as the plus and minus sides of the music
signal are transmitted separately. Noise theoretically flowing to the ground can be
ignored. If external noise occurs and disturbs the mutual waveform, the disturbance
is canceled out at the end of the transmission when the plus and minus sides are
combined, enabling the original music signal to be output free of noise. Superior-quality
sound expected of a flagship system is produced.
