Unique solutions helping improve what matters most - the sound.
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. More than 10 years of research and development have made it possible to reproduce music in a more natural way than ever before.
After converting the digital CD data to the analog domain with the SyncroDAC converter, the high frequency noise has to be removed from the analog signal. This prevents high frequency noise from the conversion process to reach the pre-amplifier and power-amplifier in the audio system. High Frequency noise will reduce the linearity and resolution of the complete audio system. The linear phase low pass filter will remove the high frequency noise from the analog signal, and keep the phase information intact. The LineDriver circuit block is connected after the linear phase filter, and will drive the connected signal cables with a very low output impedance. LineDriver is using true balanced technology to reduce distortion and preserve resolution.
All Hegel amplifiers are using a new kind of distributed amplifier technology. DualAmp is used in all integrated amplifiers and power amplifiers from Hegel. In normal audio amplifiers the voltage gain stages and current gain stages are combined in the same amplifier module. DualAmp Technology from Hegel separates the voltage gain stage and the current gain stage into two completely different stages. First the music signal goes to the voltage gain stage, amplifying only the voltage level of the music signal. By doing only voltage gain in this first stage, we can use amplifier building blocks that are specially designed to do voltage amplification. After the separate voltage gain stage, we have the current gain stage, doing only current gain.
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 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, from Youtube videos to Skype chats, with Hegel sound.
As a story is told from person to person, details change. Things are added, others lost. At some point, the story has changed. When a music signal is passing through an audio amplifier a similar effect will take place. As the signal is passed from stage to stage within the audio amplifier, the music signal will be changed by every single amplifier stage. When the music signal finally reaches your loudspeakers, the signal is different from the original music signal from the signal source. The SoundEngine local error cancelling system prevents distortion in the audio amplifier circuit stages, preserving the original details and the dynamic range in the original music signal. The end result is a much cleaner music signal with a larger dynamics and low distortion.
In a CD Player one of the most important parts is the master clock signal. It's 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. 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.
Normal audio amplifiers are using the same power supply for the different amplifier blocks within the audio amplifier. The amplifier output stage driving the loudspeaker is using the same power supply as the crucial input stages and voltage gain stages of the audio amplifier. The large currents flowing in the connected loudspeakers will disturb the sensitive input- and voltage gain stages of the audio amplifier. Hegel integrated amplifiers and power amplifiers are using completely separate DualPower power supplies for the input and voltage gain stages, and for the current output stages of the audio amplifier. The custom designed power transformers have separate DualPower windings feeding independent high speed rectifiers and capacitors.
Almost all CD Players today are using asynchronous upsampling to convert digital audio data to analog audio. Hegel found that using this kind of asynchronous converter technology will convert jitter error into amplitude error, giving less than optimal sound quality. The Hegel CD Players are using a new digital to analog conversion technology called synchronised upsampling. This new technology gives higher resolution and less distortion. The syncroDAC technology is used together with the Direct MasterClock technology to keep jitter error and digital to analog conversion errors to a minimum. This will give a cleaner sound and a higher resolution. SyncroDAC is using true balanced signal processing to preserve highest possible dynamic range.
