The H30A is The Orchestra. With its immense power, speaker matching is no longer an issue. The Orchestra can play any "venue", be it large stadiums or small cellar clubs, and with its unsurpassed skill and attention to detail, no music is too challenging. It conveys all music like you never thought possible. No matter what or where it plays, The Orchestra will always perform at its best. The H30A is the best orchestra you will ever experience.

The H30A is our reference power amplifier. We have nicknamed it The Orchestra because that is what it is. The H30A's job is to take command of any music on any speakers and make it sound as good as possible without ever breaking a sweat, and we can think of no more challenging music than a large orchestral piece. The H30A is an absolute powerhouse of an amplifier. In its mono state, it delivers a truly astounding 1100 watts in 8 ohms, and it is completely stable even with 1-ohm loads. To achieve this, we have applied all our skills and knowledge in amplifier design and combined that with the best electronics. The H30A power supply uses 2 separate 1000 VA toroidal transformers for fast response and minimized transformer hum. With a power bank of 270,000 μF capacitors, the H30A can handle even the most challenging piece of music at any volume, it always has enough power in reserve. In the output stage, we use 56 pieces 15A 200W high-speed, ultra-low distortion bipolar transistors. With so much power ready at any given time, things like speaker sensitivity and variation in loads no longer come into play. With the H30A you can confidently drive any speaker you like.

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 to 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.

Power is, however, nothing without the details to match. In a large power amplifier like this, the input stage is especially vulnerable to electrical interference distorting the music signal. One troublesome type of distortion is higher-order harmonic distortion. It is a distortion far removed from the original music frequencies and can often make the amplifier sound harsh and unmusical. We eliminate this in the H30A input stage by using single-pair FET transistors. These are carefully hand-matched transistors that have the exact same values, and therefore they have no higher-order harmonic distortion. Other types of distortion we cancel out with our patented SoundEngine2 technology. This actively monitors the music signal for corruption and corrects it for distortion using a feed-forward design. SoundEngine2 effectively removes distortion in real-time as the signal is amplified. These measures make the H30A sound smooth and natural without compromising details.

All Hegel audio amplifiers use a new kind of distributed amplifier technology called DualAmp Technology. This technology is used in all integrated amplifiers and power amplifiers from Hegel. The voltage gain and current gain stages are combined in the same amplifier module in normal audio amplifiers.

DualAmp Technology from Hegel separates the voltage gain and current gain stages 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.
