1. All channels of the Denon amplifier A/V amplifier have the same output power and frequency response, ensuring that various high-quality program sources can be played back completely faithfully: from two-channel stereo to advanced DVD-Audio, Super audio CD and 5.1-channel A/V program sources, such as Dolby Digital and DTS. It can also provide 6/7-channel equal power and equal response output for 6.1-channel program sources such as Dolby Digital EX and DTS-ES to ensure the best results. The power supply section of DENON amplifiers and receivers uses large power transformers, large-capacity filter capacitors and other parts optimized for excellent audio characteristics to create a sound that is both thrilling and nuanced.
2. When the PCM digital stereo signal is input to D/A decoding and processing, DENON's latest ultimate analog waveform reproduction technology, namely the Advanced AL24 Processing function, exerts its power in real time. In addition to the original "AL24 Processing Plus" message expansion technology, new DSP and FPGA large-capacity computing processing hardware are added, and based on DENON's exclusively developed (algorithm) digital computing program, new data is inserted into the timeline and upsampling is performed rate, natural interpolation processing without loss of the original signal. In addition, the adaptability of the digital filter is greatly expanded. This advanced AL24 processing circuit will analyze the shape of the input signal and automatically select the most suitable filter curve, corresponding to pulse-free ringing response, pulse-type music signals and percussion. In addition, when "Advanced AL24 Processing" is working, the D/A decoder automatically switches to double differential mode (one is responsible for one channel), which can naturally reproduce the subtle aftertaste of the music, the position of the performer, and the performance. The length, width, height and other spatial conditions of the site. Furthermore, when a Linear PCM (Linear PCM) multi-channel signal is input, DENON's original analog waveform reproduction technology "AL24 Processing Plus" function can work in all channels, making the playback of the multi-channel signal closer to the original sound. .
3. In 1993, DENON disclosed ALPHA processing for the first time. This technology can expand the 16-bit digital signal stored in the CD to a 20-bit sound signal that is close to the original sound.
This marks the beginning of ALPHA's analog waveform reproduction technology in the history of audio. With the emergence of various new digital optical disc media, such as DVD and Super Audio CD, ALPHA processing has further developed. This evolution has progressed from AL24 processing and AL24 PLUS processing to Advanced AL24 processing, which can finally achieve in addition to digital elements ( bit), new data can be inserted on the timeline and the sampling frequency can be increased.
With the advent of Blu-ray discs, DENON developed a more advanced Advanced AL32 process, further expanding the number of bits from 24 to 32, reflecting the ultimate audio performance of Blu-ray discs. Advanced AL32 processing enables more realistic playback of the original sound, providing distortion-free sound details, accurate sound localization, and rich low-frequency playback.
In DVD-A1UD, this newly developed Advanced AL32 processing is applied to the 2-channel balanced audio circuit and the 8-channel audio circuit to form Advanced AL32 multi-channel processing, bringing out this reference-level The true power of Blu-ray players.
4. AL24 Processing is DENON's proprietary analog waveform regeneration technology, and DENON has improved it to support DVD-Audio with a sampling frequency of 192kHz. This new technology, called AL24 Processing Plus, can completely suppress the quantization noise generated when D/A conversion of LPCM signals, making low-level signals clearer and showing all the subtle details in music. In the high-end model, all channels are equipped with AL24 Processing Plus.

For the past decade, people have been dreaming of being able to drive low-impedance speakers. Unfortunately, this dream is indeed a difficult proposition. DENON finally realized that a new method must be used to achieve it, which is the UHC single-ended push-pull circuit.
This circuit not only has high output power, but also can fully express the details in music. It is the first advanced solution of its kind that can solve this problem well. The challenge faced by DENON is that the amplifier must have sufficient dynamic strength to transmit the energy emitted by the player completely transparently, and it must also be able to quickly reflect every change in the music signal. The most important thing is that there must be a powerful power supply with sufficient power reserve, and the power amplification part must be able to provide a pure, large dynamic signal to the speaker, so that the sound heard can be absolutely transparent. At the same time, the amplifier is also required to have good transient response characteristics, so that even low-level signals can be accurately amplified. No matter how much dynamic range or frequency response there is, there is no point if the amplifier cannot immediately follow the sudden rise and fall of the sound.
Leakage-free (LC) dual power transformer for wide dynamic range and low noise:
The power transformer adopts a large magnetic circuit and low magnetic flux density design, which has extremely high Good response characteristics, can adapt to music signals with a large dynamic range even in the magnetic saturation area. The leak-free installation method can eliminate mutual interference caused by magnetic fields or other factors, significantly reducing magnetic leakage, thereby eliminating a major source of noise inside the amplifier, making the amplifier a powerful driving source, ensuring very transparent sound and extremely Low noise.
