Key Technologies

Audionet-Ultra-Linear-Amplifier (ULA)

Audionet’s worldwide respected and award-winning ULA (Ultra Linear Amplifier) technology is of fundamental importance for our outstanding technology. This highly complex circuit topology, initially conceived with medical engineering in mind, delivers metrological results which mark a limit of feasibility. Even under the most severe strain or in other stress situations signal impurities are barely traceable, and the high return loss guarantees that even the most demanding loudspeakers will perform faultlessly up to their utmost limits.

 

 

Audionet Operational Amplifier

Audionet operational amplifiers (OP) are used in our devices at most sound-critical parts of the circuit design to deliver the very best tonal results. Usual operational amplifiers, available in different quality and price ranges on the global market, can’t satisfy our core demands for perfect sound quality. Even the most expensive ones with the best results on paper aren’t perfect. That’s why we have designed our own operational amplifier technology. Any single Audionet OP contains at least 86 parts and components, and our topology ensures an impressive gain-bandwidth-product of 1 GHz.

 

Audionet Aligned Resonance Technology

Audionet Aligned Resonance Technology (ART) decouples the read-out unit and the control board from the housing. A mounting system ensures that damaging movement energy is dissipated in a targeted fashion and that the read-out process is subject to a minimum of disturbance. The reading module is a solid tape deck fitted in full aluminium, dampened with heavy foil, sitting on acoustically friendly brass pins. Developed for professional use, the new drive has an exceptionally robust mechanical and electronical construction. It guarantees the highest read-out quality and stability as well as excellent disc acceptance both in terms of surface quality as well as copy protection procedures. Further innovations are the puck and its cylindrical receiver. These two precision rotation parts fit together exactly without any play. The reduced contact surface and the low revolution impulse work together with an exceptionally strong, ring-formed magnet to produce a strong and even contact pressure. The pre-load guarantees an exceptionally stable and smooth disc run.

Asynchronous Upsampling

With the D/A conversion we’ve focused our highest attention on eliminating jitter, the wobbling of digital signal slopes. Jitter faults curtail the sound reproduction in every respect: imaging, stage and depth rendition will be impaired. The conversion is done using Audionet’s Intelligent Sampling Technology which guarantees an absolutely flawless recovery of the analogue signal from the digital bit stream. For this purpose the data are sent through a sophisticated, two-stage filtering and decoupling procedure. First the input data are filtered with Audionet’s proprietary software using a powerful signal processor and upsampled synchronously. The filters have been designed under audiophile aspects with regard to an optimised transient and frequency response. The thus optimised data are then resolved through an asynchronous upsampling procedure at 192kHz/24bit. Hereby the bit stream is completely isolated from its input clock and its associated jitter. The data are then fed to high-performance converters, which are clocked by special ultra-precision quartz crystals, and individually processed per channel into analogue signals. This method ensures that jitter faults are almost entirely eliminated in the analogue signal. No information gets lost and every bit of information will be processed at the right time, bringing forth an unmatched clarity, room depth and stage imaging.

 

Audionet Link

For your convenience, Audionet devices have the ability to remotely switch on/off other Audionet units (e.g. power amplifiers or source devices) connected via Audionet Link by a simple touch on the remote control or the ‘power’ key on the front panel. All you need is a humble optical ‘Toslink’ cable. Just connect the Audionet Link output to an Audionet Link input of the unit to be controlled.

Mains Phase Detection

The correct polarization of mains is highly important for reasons of audio clarity and stability. Please connect the mains cord so that the ‘hot’ pin of the wall outlet is connected to the pin marked ‘phase’ of the mains input on
the back panel of your Audionet device. Your Audionet device will conveniently instantly recognize any incorrect polarization of the mains plug automatically and alert you to this musicalitywise potentially grave mistake on its display or by its power LED. Should this event occur, just switch off the unit by pressing the ‘power’ key. Now pull the mains plug and re-insert it into the mains socket rotated by 180°. That’s half of a turn, for all non-scientists.

 

Double-Precision-Bassmanager and Parametric Equalizer

The digital signal processing is accomplished with efficient signal processors and our proprietary Audionet software which was developed and continuously improved exclusively under audiophile aspects in more than 15 years of painstaking scientific labour.

The double precision bass management uses a 48bit resolution at all sampling frequencies. Even the very lowest frequencies are therefore precisely reproduced and accurately processed. The bass manager offers freely selectable cutoff frequencies, filter Q factors and subwoofer phases. Thus you can perfectly integrate your subwoofers into the system and into the room.

The digital parametric equalizer uses Minimum Phase Equalizers (MPE) both for the main channels and subwoofer channels. For each MPE the filter type, frequency, gain and Q factor can be selected within an unusually wide adjustment range and disturbing room interference and tonal annoyances efficiently compensated. In combination with CARMA, our computer aided room acoustics measurement system, it is possible even for non-professionals to reach nearly professional results.

The delay manager has an adjustment range of up to 7 m and automatically calculates the delay times from the distances.
