Introducing the next generation of Hegel D/A-Converters - The HD12,
introduces a combination of great new functionality as well as greatly
improved sound quality. First of all, a brand new USB interface allows
you to use all common sampling frequencies up to 24 bit / 192 kHz. Also,
this new interface allows playback of native DSD-files (PC only),
without conversion to PCM. Furthermore, the HD12 has equal quality on
the 2 optical and 1 coaxial inputs. Versatility - With an HD12 you can
upgrade virtually any system to Hegel standards. There is a very high
quality headphone output, regular RCA phono outputs as well as true
balanced XLR outputs. This means you can connect to any
receiver/amplifier and/or subwoofer. However, the built-in and
remote-controlled volume attenuator also allows direct connection to a
pair of active loudspeakers or to a power amplifer. High End to the
Sound - New research in the digital domain has resulted in extremely low jitter levels. In particular, great improvements have been made to “skirting”, a distortion that reduces the timing and precision in the sound. You hear it very well in drums and dynamic elements of the music. Another large improvement comes in the analog part of the D/A-Converter. We are talking about a noise floor of -145dB. It means the HD12 brings out so much more of those tiny details that suck you in to the music.
Quite simply a significant upgrade and a remarkable D/A-Converter.
In a CD player one of the most important parts is the master clock signal. The master clock is controlling the rhythm of the CD player by telling the DAC chip exactly when to convert the audio signal from digital to analog. To have the best possible sound, it is vital to have a master clock that has a very stable clock frequency and lowest possible jitter. Jitter is timing errors in clock generator circuits. A master clock generator should have a very stable time period. If the timing period of the master clock generator is moving back and forth in time this timing error is called jitter. Jitter for a clock generator is measured in pico seconds, and the number of pico seconds of timing jitter is a measure for the quality of the clock generator.
To have the best possible sound, it is best to have a lowest possible jitter value. All Hegel CD players have less than 10 pico seconds of jitter. There are many mechanisms that can generate jitter in a master clock generator: power supply noise, clock oscillator topology, quality of quartz crystal resonator, clock driver circuit and circuit board layout. Most CD players are using a master clock located at the CD servo-decoder board in the CD player. Because the servo-decoder board has got a lot of high- and low frequency noise from the CD servos and the digital CD decoder circuits this is not a good solution. A Master Clock generator on the CD servo-decoder board will have an unstable frequency and high jitter because of the high levels of signal noise and power supply noise on this board.
In addition to having the Master Clock generator on the CD servo-decoder board, many CD players are also using a SPDIF serial digital interface from the CD servo-decoder board to the DAC-board, and this will give decreased sound quality because of digital audio data related jitter. The most expensive CD systems are using a separate Master clock generator that is connected to the CD servo-decoder and to the DAC board. This is an expensive solution, but will always give the best sound. All Hegel CD players are using a very high precision Master clock generator with extremely low jitter, and this Master clock generator is located on the DAC board inside the CD players. This high precision Master clock is distributed directly to the DAC chip and directly to the CD servo-decoder board. In this way the performance of the Hegel master clock generator is equivalent to very expensive CD systems.
Good recordings are best enjoyed naked. The organic sound of Hegel means that all parts of a dynamic recording are reproduced exactly like the original. The quality of the sound coming out of your speakers are only limited by what happened in the recording studio. Nothing added, nothing taken out - no artificial ingredients. Music enjoyed on a Hegel system is the closest you can get to the live studio session. We are proud to present The Hegel Concept - the first music system in the world that utilizes the very latest technology from all related fields, like integrated circuitry, broadcasting technology and telecommunication. More than 10 years of research and development have made it possible to reproduce music in a more natural way than ever before. Our goal is give music lovers the most natural and engaging listening experience possible. Real life sound from acoustic instruments and voices from known artists were our preferred reference point while developing Hegel, because nothing else would do.
The USB connector found on Hegel amplifiers and digital to analogue converters opens a whole new world for music and movie lovers. This functionality allows you to easily connect your Hegel product to any computer with a reasonably new Windows or Mac Os operating system installed. The most common Linux systems will also work. The Hegel USB technology is actually a computer sound card, or audio controller if you like. With the Hegel product connected, all sounds usually played through your computer will now be played through the Hegel. This means that, unlike let's say a music streamer, a Hegel DAC will not only play your music files, but also any sounds that come out of the computer, including Youtube videos or Skype chats.
What can it play? The Hegel will, when connected take over all sounds. This means you can play music, video, computer games, internet radio or hear the occasional ding when you press and hold the Windows ANY-key for too long. Everything with superb Hegel sound. The major benefit is noise reduction. Inside a computer you have all kinds of noise generating equipment. And especially the very low-gain analogue signal is very exposed to noise inside a computer. So just moving the sound card out of the computer gives a real benefit. So what is so special about the Hegel sound card? Well, it is not like computer manufacturers have not tried to do their best for years. And many of our competitors have tried doing great separate sound cards too, these last couple of years. The special thing with Hegel is that we do real life experiments. For example we found that the DAC-chip it self only had limited importance. The implementation of it, however, had a major impact on the sound. Compared to any other external USB sound card you will find the Hegel more quiet, more dynamic and with less distortion.
