DENON Link: Connected via a shielded twisted pair (STP) RJ-45 fi tted cable to
a DENON Link-compliant A/V amplifier, the balanced signal transfer offers lower
voltage than coaxial or unbalanced cables. Since DENON Link is far less
susceptible to radiated noise, it ensures the highest level of signal transfer.
The DENON Link interface is able to transfer high-grade LPCM 24-bit, 192-kHz,
2-channel and 96-kHz, 24-bit, multi-channel digital output.
Advanced AL24 Processing: DENON led the world in developing a practical
PCM recorder in 1972. The shift to digital technology solved numerous problems
such as noise, wow, fl utter, and frequency response. The delicate nuances of sound from
CD up to the least signifi cant bit (LSB) are lost, however, due to the 16-bit quantisation and
band cutting at fs/2 (half the sampling frequency) during 44.1-kHz sampling. DENON was
determined to tackle the problem of quantisation noise that remained in digital audio, and
developed ALPHA (adaptive line pattern harmonised algorithm), a technology that reproduced
16-bit data with 20-bit quality and became a favourite with audiophiles around the world.
This development later progressed to 24-bit quality with the evolution of "AL24
Processing," and as support for higher resolutions and sampling continued to improve,
DENON developed "AL24 Processing Plus" for the 192-kHz sampling of DVD-Audio.
DENON's most recent achievement is "Advanced AL24 Processing," a proprietary high-
speed signal processing technology that expands the volume of data along the time axis
in addition to the data expansion of existing AL24 Processing Plus technology.
AL24 Processing Plus: DENON has further developed its proprietary AL24
Processing, an analog waveform reproduction technology, to support the 192-kHz
sampling frequency of DVD-Audio. This new technology, called AL24 Process-
ing Plus, thoroughly suppresses quantisation noise associated with D/A conversion of
LPCM signals to reproduce the low-level signals with optimum clarity that brings out all
the delicate nuances of the music. In high-end models, AL24 Processing Plus works for all
channels.
LAMBDA SLC: The LAMBDA Super Linear Converter (SLC) design includes a LSI,
developed by DENON, that divides the digital data into two streams to eliminate zero-
cross distortion in a powerful DAC confi guration. In the two data streams, there is no
reversal of the MSB (Most Signifi cant Bit), and the combined waveform also shows
no zero-cross distortion. Even if there is distortion in the original information for a
certain bit, the two signals are averaged, reducing the distortion by one half. On the
other hand, if the signal level is larger than the amount of shift, the waveform will pass
through the usual, unbiased zero-cross point and any distortions in the signal will then
be reliably eliminated by the MSB compensation feature of the SLC.
DDSC-Digital HD for high-quality sound reproduction for high defi nition
source: DDSC (Dynamic Discrete Surround Circuit)-Digital is a circuit confi guration
specially designed by DENON in which all elements of the surround proc es sor
are optimised through the use of selected high-performance discrete com-
ponents, including separate A/D and D/A converters, with sophisticated DSP sur-
round decoding. DDSC-Digital HD is a newly developed engineering design now for
HD source.
Compressed Audio Restorer: Typical compressed audio formats like MP3, AAC,
WMA, etc. delete the high frequency signal data substantially while thinning out the data
signals, which results in the loss of clarity of the sound. The ‘Compressed Audio Restorer
’ restorers the compressed audio signal as close as possible to the original by interpo-
lating and generating the missing data during compression. Added high frequency ele-
ments in the compressed audio data place a disproportionate emphasis on the band
spreading. The ‘Compressed Audio Restorer’ fi ne-tunes the data signal in all frequency
by generating harmonic overtone of low frequency. The ‘Compressed Audio Restorer’
gives second life to the compressed audio data to make them more comfortable and
pleasant to listen to by adjusting and clarifying the details of the music sound and improv-
ing their stereo image. The quality of the compressed audio signal depend, of course, on the
quality of the original source, however, is determined by the compression technology and the
transfer bit rate. The ‘Compressed Audio Restorer ’ has 4 modes (Restorer64/Restorer96/
RestorerHQ/OFF) and offers most effective performance to any compressed audio signals.
All channel equal circuit: DENON's A/V amplifi ers and receivers are endowed
with power amplifi ers that deliver equal power and response to all channels, ensur-
ing utter fi delity to a wide range of high-quality sound sources, from 2-channel stereo
to advanced DVD-Audio, Super Audio CD, and Multi channel A/V sources such as
Dolby Digital EX and DTS-ES. This all-channel equal circuit gives you the same
quality sound in any format and in all channels.
The power sections of DENON's A/V amplifi ers and receivers use large transformers,
high-capacity block capacitors, and other parts specially selected for their high-
quality sonic characteristics to give you a robust yet wonderfully detailed sound.
Pure audio construction: A/V components contain analog audio, digital audio,
video, control and many other circuits. The various circuits and blocks in DENON’s
A/V amplifi ers and receivers are thus separated and shielded to prevent mutual
interference among them. High-end models are designed with the power supply
section in the centre and the power amp section on both sides as in a Hi-Fi amplifi er.
