H 80 este cel mai mic amplificator integrat din oferta producatorului norvegian Hegel.
3 analogice (2 x nebalansat RCA, 1 x balansat XLR)
5 digitale (2 x optic, 2 x coax, 1 x USB)
Etajul de preamplificare este fara compromisuri, similar cu cel folosit in produse de varf.
DACul integrat are multe in comun cu DACurile separate fabricate de catre Hegel. Nu necesita drivere, este plug&play.
Etajul de iesire foloseste SoundEngine, o tehnologie care reduce mult distorsiunile si mareste damping factorul amplificatorului.
Conexiunea USB permite utilizarea telecomenzii amplificatorului pentru a controla playlistul din computer (puteti da skip, play sau pauza din telecomanda).
Hegel H 80 ofera putere, control si dinamica, mult peste ce puteti gasi in amplificatoarele din aceasta gama de pret.
All Hegel audio amplifiers are using a new kind of distributed amplifier technology called DualAmp Technology. This technology 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 and nothing else.
This way we can use amplifier blocks that are specially designed to do current gain. The current gain stage is needed to deliver a lot of current to the loudspeakers connected to the audio amplifier. By separating these two stages, we can keep the sensitive parts of the voltage gain stages away from the large speaker currents in the current output stage. The output of the voltage gain stage is connected to the input of the current gain stage. There is no feedback from the current gain stage to the voltage gain stage. The Hegel DualAmp technology gives lower total distortion and a higher dynamic range than normal audio amplifiers. The Hegel DualAmp technology is developed in-house by Hegel, and is only found in Hegel products.
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 Hegel power transformers have got separate DualPower windings feeding independent high speed rectifiers and high capacity power supply capacitors.
By using the DualPower power supply technology Hegel amplifiers will prevent disturbances from the high currents flowing in the loudspeakers entering the sensitive input gain stages and voltage gain stages. The Hegel DualPower technology gives lower total distortion and a higher dynamic range than normal audio amplifiers. The Hegel DualPower technology is developed in-house by Hegel, and is only found in Hegel products.
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.
It'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.
