Hegel H30A - Reference Power Amplifier

(PDF)The new Hegel H30A Reference Power Amplifier has been nicknamed "The Orchestra." With its solid power, speaker matching is no longer an issue. The H30A is Hegel's reference power amplifier.

The Hegel H30A’s job is to take charge of the music on any speakers and make it sound as good as possible without missing a step. Few can think of any more challenging music than a large orchestral piece to reveal an amplifiers true performance.

Incredible Power

The H30A is a beast of an amplifier. In mono mode it delivers an astounding 1100 watts in 8 ohms, and it is completely stable even with 1-ohm loads. To achieve this, Hegel have applied all their skill and knowledge in amplifier design and combined that with the best electronics.

State-of-the-Art Power Supply Section

The H30A power supply uses 2 separate 1000 VA toroidal transformers for fast response and minimised 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.

On the output stage Hegel has used 56 / 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.

Input Distortion Reduction and Sound Engine Technology

With the Hegel H30A you can confidently drive any speaker you like. 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 type of distortion that is far removed from the original music frequencies and can often make the amplifier sound harsh and unmusical. In the H30A input stage this has been eliminated by using single pair of 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 are cancelled out with Hegel's patented Sound Engine technology. This actively monitors the music signal for corruptions and corrects for distortion using a feed forward design. Sound Engine effectively removes distortion in real time as the signal is amplified. These measures make the H30A sound very smooth and natural, without compromising on the details.

Mono and Stereo Modes

The H30A is designed as a mono power amplifier, but it can also be used as a stereo power amplifier. It has both balanced (XLR) and unbalanced (RCA) inputs and a 12V trigger input. For the best possible connection, the H30A features high quality, gold-plated speaker binding posts.

New Levels of Clarity and Detail

Usually, when going from one amplifier to a more powerful one, you experience more of everything. More bass, more details, more involvement – everything is just more.

Because the H30A is so immensely powerful and detailed, the concept of “more” simply becomes irrelevant. In the H30A the bass is tremendously deep, but never dominating. The high frequencies are exceptionally detailed, but never fatiguing. And the articulation of vocals in the midrange is just sublime. At this level, what you experience is simply total control.

The H30A is an amplifier that can drive virtually all known loudspeakers with authority and ease. It never sounds forced, only relaxed and musical. The H30A is the spearhead of Hegel amplifier technology. It is the large orchestra that brings life to any music in any venue.
