Complete attention to detail not only for sound but also for design, materials, parts, and crossover network; the uncompromising skill and passion of a craftsman. Denon's CX1 delivers authenticity in sound required by the most discerning audiophiles.  It consists of the DRA-CX1 and the DCD-CX1.

DRA-CX1 - Stereo Receiver

The DRA-CX1 delivers sound of uncompromised quality, a pure audio hallmark of Denon. Every aspect of Denon audio technology that has been devoted to the DRA-CX1 is designed to maximise the beauty of sound.

Newly-developed amplifier circuitry, for improved power and clarity in music playback 

Denon has newly developed its amplifier circuitry for Hi-Fi audio to achieve a high electric power conversion efficiency of around 90%. Despite the DRA-CX1's compact size, it delivers a powerful output of 150W + 150W (at 4ohms) for superior speaker drive. In addition, the circuits of the preamp section and the power amp section, including their power units, are completely separated from each other to minimise mutual interference on the signal and ensure that the music you hear is powerful and clear. A hybrid module construction where the shield and heat sink are mounted directly onto a metal plate has been adopted to efficiently discharge heat and provide optimum shielding for high-frequency signals. Analyses of reliable technologies and careful listening have resulted in the ability of the DRA-CX1 to reproduce the full range of musical experience, from delicate nuances to dynamic sound. 

Power unit capable of responding to sudden bursts of sound 

The DRA-CX1 is equipped with a power circuit capable of efficiently supplying highly stable electrical current. This compact circuit excels at supplying power in an instant, ensuring that there is always an efficient supply to support stable music playback. This power circuit uses a unique control system developed by Denon to ensure there is sufficient current even for instantaneous peaks in the sound. This system thus accurately reproduces such sounds as delicate guitar picks and powerful attacks by percussion instruments. In addition, an original Denon capacitor meticulously designed for high sound quality is used for the electrolytic capacitor in the output stage power circuit to achieve a stable, high-grade supply of power. 

Highly precise electronic volume 

The DRA-CX1 has a highly-reliable, high-precision volume control that can be adjusted in 0.5dB increments. Volume can be controlled independently for left and right channels, and realises a simple signal path that does not require any complex circuitry. The volume knob is constructed of a combination of natural briar wood and highly-rigid machined aluminium to sufficiently suppress the adverse effects of vibration and influences on sound quality. 

Separate power supplies and ground circuits for each stage 

To eliminate signal degradation caused by current leakage, the output stage, digital signal processing stage, analog signal processing stage, the control circuit around the microprocessor, the display circuit, and the signal switching relay each have their own power supply and ground circuit. This design ensures that sound quality is not degraded by mutual interference from the power supplies among the circuits or by current flowing into the ground circuits that form the foundation for amplification. 

Short Signal Path Circuitry, to suppress signal degradation 

The DRA-CX1 features a simple and straight signal path, designed to preserve the purity of the original sound. Since a relay is used for switching input signals, adverse influences caused by resistance when the power is on have been eliminated and the signal path has been shortened as much as possible to prevent signal degradation. A Pure Direct mode is also provided, allowing the signal to bypass the tone circuit and further shorten the signal path for an even cleaner sound. 

DCD-CX1 - CD/Super Audio CD Player 

The DCD-CX1 CD player embodies the culmination of a host of digital audio technologies that Denon has contributed to the evolution of CD players. From mechanisms that thoroughly suppress vibration to the meticulous reading of music information and the ability to faithfully reproduce the original sound, Denon has significantly raised the standard of maturity for CD players.

Newly-developed mechanism to accurately read information from the disc 

To achieve the ability to reliably and accurately read information from the disc within a player of slim design, the DCD-CX1 incorporates drive mechanism technology originally developed for Denon's top-end players combined with newly-developed improvements. To improve reading accuracy and realise optimum signal reproduction and playability, the pickup section, vital for reading information from the disc, has been minutely adjusted in the manufacturing process to eliminate misalignments in the optical axis of the laser beam and to ensure a correct angle for the base of the pickup mechanism. The elaborate design that suppresses vibration caused by high-speed disc rotation or vacillations ensures that even eccentric discs can be played without causing vibration. Anti-vibration construction has been introduced in other areas as well. To thoroughly absorb vibrations from the mechanism itself or from external sources, the disc tray has been made of diecast aluminium for improved rigidity and diecast zinc has been used for the mechanism base, allowing the pickup to read information on the disc with even greater accuracy. 

AL24 Processing, to dramatically enhance the music listening experience 

AL24 Processing is a high-grade analog waveform reproduction technology developed by Denon to support lower quantization noise and higher sonic resolution and sampling. This technology dramatically improves the player's ability to reproduce the moments when music quietly fades away or instants when it starts following complete silence. 

Highly reliable DAC master clock design 

To secure reliable oscillation accuracy, the DCD-CX1 uses a DAC with a solid track record of performance in Denon's high-end CD players as the master clock to supply signals to the various devices. This meticulous design minimises the influences of jitter and realises a clear, high-quality sound with gentle curves in the sonic image. 

Separate digital and analog transformers, for stable power supply and improved music playback performance 

A dual-transformer configuration has been adopted for the DCD-CX1 to eliminate mutual interference between the digital and analog circuits and achieve greater playback clarity. The digital and analog circuits, including their transformers, are completely independent, and together with a capacitor renowned for superior sound quality performance, the power supply is constantly stable and clear. 

Pure Direct mode, for the enjoyment of pure music 

The DCD-CX1 includes a Pure Direct mode to lend greater purity to the playback sound. By turning off the pulse signals for the display and digital data, adverse effects on the audio signal are eliminated to produce a purer music playback environment.

SC-CX1 - Speaker System 

Deep, rich texture and beautiful, natural sound. State-of-the-art audio technology incorporated in traditional speaker engineering and uncompromising craftsmanship combine to produce a refined speaker system dedicated to an exceptional music listening experience.

Newly-developed 13cm D.D.L. cone woofer units utilising carbon fiber 

D.D.L. (DENON Double Layer) cones utilising carbon fiber, renowned for superior rigidity and light weight, have been used in the woofer diaphragm. The dual-layered diaphragms, configured through detailed simulation, have been carefully structured to achieve accurate piston motion across a broad spectrum and prevent edge vibrations from adversely affecting the woofer's sonic characteristics. Combined with the highly-refined magnetic circuitry, these speakers deliver a sense of musical presence on a scale of grandeur that seems unimaginable for their compact size. 

Soft dome tweeters, to realise a lustrous vocal sound 

The tweeters feature 2.5cm soft dome diaphragms to reproduce a natural acoustic effect, and highly magnetic, low-distortion neodium magnets have been used in the magnetic circuitry. In addition, an aluminium diecast chamber has been placed at the rear of the tweeter unit to improve the tweeter's low-range characteristics and produce more lustrous vocal sounds. Ventilation holes have been added to prevent the dome from swelling when the air inside heats up and to maintain uniform centering of the diaphragm. The ventilation holes also prevent the voice coil and other sources of heat from subtly affecting the sound. 

Crossover network, for uniform sound pressure and phase response 

The basic design of the network has been carefully considered not only in the energy and phase characteristics of the unit but in the acoustic reflections of the cabinet and placement conditions as well. There are independent network circuits for the tweeter and the woofer, and direct wiring rather than boards has been used in the configurations. Floating mounts on the cabinet have been used to minimise vibration and other adverse effects on sound quality.

Unit frame made of non-magnetic diecast aluminium to keep sound clean 

The unit frame has been made of non-magnet diecast aluminium to protect it from the movement of the diaphragm. A damping material has been used between the frame and the cabinet to float mount it, and the screws used to mount the tweeter unit frame (indicated in red in the diagram at the right) are also float mounted, to thoroughly suppress acoustic reflections. 

Cabinets made of 30mm MDF board with natural wood sliced veneer and inlaid work 

The cabinets of the SC-CX103 have been fully constructed with 30cm thick medium-density fiberboard (MDF) and beautifully finished with a semi-glossy natural wood sliced veneer. The natural wood finish is not only pleasing to the eyes but also has the beautiful acoustic effect of controlling sound waves transmitted to the surface. Also, delicate natural wood inlay has been added to the upper and lower areas of the baffle and in the corners of the sides to enhance rigidity as well as the beauty of the finish and to control the acoustics of the overall cabinet. 

Born from European sound design and Denon collaboration 

The SC-CX1 was jointly developed by skilled European sound engineers and Denon. The high standard of craftsmanship emerged as a result of assiduous analysis, tests, and adjustments that were repeated over and over again with the latest technologies and materials to achieve optimum clarity and depth in sound.
