Characteristics

The Interface that Excels

The creation of the DNC (Digital Network Client) began with a single aim: to build the best sounding and most versatile network client and digital/analogue converter possible, capable of interacting with all current music reproduction sources. R&D was allowed to operate with uncompromising rigor and dedication at all phases, leading to the DNC’s astonishing, powerful performance, innovative analogue signal processing and circuit design. It is a truly universal interface for digital music. Reading from computers, servers, HDD, USB sticks and streaming from the internet – via cable or wireless – the Audionet DNC will turn any digital music data into a captivating musical experience.

Audionet’s DNC, considered a premium choice among elite network clients, allows an ease of use that is uncommon in the high-end audio world. With intuitive and powerful apps, it interfaces with all tablet PCs and smart phones, including all members of the Android and iOS operating systems (Audionet aMM – Audionet Music Manager for AndroidAudionet iMM – Audionet Music Manager for iOS). The Audionet DNC is the first network client and Digital to Analog converter able to be fully integrated into a network and operated entirely by a PC or Mac. Our in-house developed software RCP (Audionet Remote Control Point) allows the user to organize complex functions and settings effortlessly through a GUI (graphic user interface).The RS-232 interface allows in addition for professional integration into home automation systems. At long last it can also be controlled in the classic way with the Audionet RC2 Remote Control.

The Audionet DNC’s unique functions provide for a cutting-edge music experience. Our engineering team has refined our digital filter technology and integrated it into the Audionet DNC. It is the first network client and Digital/Analogue converter with such powerful delay and EQ management. Such precision allows for first time syncronised balance setting and effective correction for room acoustics and tonal disturbances. Each speaker ensemble can be adapted to it’s listening environment. Joined with Audionet’s analysis and correction software, CARMA, the spatial data is captured, analyzed for perfect correction, and automatically transferred to the DNC. Professional room acoustics, all the time.

The Audionet DNC is fully equipped. It can receive internet and FM radio as well as podcasts, streams music from TIDAL, Qobuz and Deezer, offers an USB 2.0 (USB Audio) and a digital USB-A interface. Each input is independently namable and can have input levels matched. The DNC features an optical Audionet input and output for remote switching between components, and utilizes a network phase monitor. The DNC is capable of using an external power supply (Audionet EPS G2 or EPX), for clean power.

The Audionet DNC offers universal digital connectivity. Nine digital inputs, including WLAN, LAN, USB, S/PDIF, electrical and optical make any network interface possible. A pair of gold-plated RCA and XLR outputs cover all analogue applications.

Technology

Construction

Over eighteen years of research and development into improvement of our components, proprietary software and the feedback of audiophiles at all stages allow the Audionet DNC to feature a sound that is rarely experienced in a streaming client. The digital and analogue sections and the correspondending power supplies are both electrically and physically strictly separated from each other and function independentely.

The digital parametric equalizer uses 5 Minimum Phase Equalizers (MPE), for main channels. Each MPE is configurable in filter type, frequency, gain, and Q factor within an unusually wide adjustment range, allowing the effective optimization of all parameters and compensation of less than ideal room characteristics or acoustical problems.

 

Signal Processing

In order to optimize the D/A conversion, Audionet’s engineers pursued the uncompromising reduction and elimination of jitter, resulting in a highly exact, musical and solid sound image, stage and depth. To this end, we have developed Audionet’s Intelligent Sampling Technology, which performs with stellar results the analogue signal recovery from the digital bit stream. Audio data is routed through a two-stage filtering and decoupling procedure. First, the input data is filtered with Audionet’s proprietary software using a powerful signal processor and up sampled synchronously, through filters designed for optimal transient and frequency response. At the next stage, the optimized data is then resolved through an asynchronous up sampling procedure at 192kHz/24bit, allowing the complete isolation from any potential jitter originating from the input clock. The resulting audio data is then passed to two high-performance converters, which are clocked by dedicated ultra high precision quartz crystals and individually processed per channel into analogue signals. This method ensures that jitter faults are eliminated – completely lossless – in the analogue signal to the highest degree, resulting in unmatched clarity, room depth, and stage imaging. In addition, power flux interferences are avoided by powering the digital section of the DNC entirely separately from the analogue section.

 

Architecture

Neither did we make any compromises with the analogue signal processing of the Audionet DNC. In a lavish research and development phase every detail has been reconsidered and tested. The circuit design and the construction are designed for maximum performance.

Audionet researches, pursues and acquires exclusively only highest quality components worldwide, requiring in many cases custom design and production. For example, filter caps are designed to our specifications using Japanese silk dielectrics, custom mica caps, and selected high-current foil caps from Germany, manufactured for an ultra low loss angle. Internal wiring is done with top-grade silver/gold alloy, and the best available connection systems from our colleagues at WTB in Essen, Germany.

As part of our quest to use only the highest-grade components available, Audionet manufactures the DNC’s operational amplifiers in house. Each Audionet op-amp contains more than 86 discrete components, and is characterized as a unique gain-bandwidth product.Signal flow and ground routing are implemented consistently in dual mono, in order to achieve maximum channel separation for high frequency characteristics, as well as circuit miniaturization and the shortest possible signal paths. The DNC’s signal flow is completely unimpeded by coils, inductors, or capacitors in the path, contributing to the DNC’s outstanding performance as an interface that excels in options and sound.

An independent power supply is included for the analogue hardware, with a 50VA toroidal transformer, 26,000 µF of filter capacitance, and a dual voltage stabilization by discrete and instantaneous voltage regulators. In addition, local voltage at each op amp is filtered again with an extra capacitance for a total of 8,000 µF.

Noise, distortions and crosstalk are reduced to a minimum and ensure a high level of energy, dynamics and purity of sound.
