bentholterThe story begins in 1988. Bent Holter - student at the Technical University in Trondheim (NTNU) decided to do a thesis under the original design of the amplifier transistor that would cure the problems of classical systems. Enemy number one - harmonic distortion. Holter somehow could not accept the fact that when we give a simple signal to the amplifier, you will get that signal plus something else - distortion produced by electronics. Fighting distortion usually meant the deterioration of other parameters, including damping factor. Holter decided to break out the classic schemes and developed a project that became the basis of what we know today as SoundEngine Technology. And where the name of the company came from? Well, after hours Bent played in a rock-metal band called The Hegel Band. When they needed amplifiers for concerts, Holter suggested building them himself. His ideas took on real shape, but it took lots of money to refine the technology. Help came from Telenor - one of the biggest players in the telecommunications industry.
The early nineties were a period of prosperity for the brand. First they ensured the patented solution known today as SoundEngine, later developed a DAC (1994) and the first CD Player (1996). Over the next eight years the company has steadily improved the product range and generated more and more profits from year to year. When the financial crisis came, most companies immediately took a defensive strategy which meant cutting costs. Norwegian designer played differently. He hired new engineers to design devices. Some time later, brand new D/A converters were born.
Today Hegel is one of the best established brands in Hi-Fi market, producing integrated, pre and power amplifiers as well as CD players and some of the most modern and sophisticated C/A converters. The SoundEngine Technology was just a start. Today there are six more original technical solutions in Hegel's portfolio. The company has dealers in 32 countries and its products are sold all over the world. Awards and press reviews speak for themselves

HegelSoundEngine-300It's a common fact: 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 Hegel 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 dynamic range and lower distortion.
The unique and patented Hegel SoundEngine audio technology is combining the advantage of class AB-amplifier and the advantage of class A-amplifiers, without having the draw backs of class A- and class AB-amplifier technologies. The SoundEngine Technology will cancel crossover distortion found in all types of class-AB amplifiers. The human ear is very sensitive to high frequency distortion components in the music signal. The Hegel SoundEngine Technology will cancel high frequency distortion components found in normal types of audio amplifiers. The Hegel SoundEngine technology is not using any kind of global negative feedback, it is using local and adaptive feed forward technology if there should ever be any need for cancellation of distortion within the audio amplifier stages.
