The Hegel P30A reference preamplifier with the Hegel H30A reference power amplifier. Get the full concert hall experience with a signal that is as true to the music as possible. The P30A preamplifier with 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.

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 we eliminate this 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 SoundEngine technology. This actively monitors the music signal for corruptions and corrects for distortion using a feed forward design. SoundEngine 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.

Fully Balanced

All these steps make for a preamplifier that is very quiet and handles the sensitive low amplitude music signal as delicately as possible. Even so, distortion of the signal can still happen, but the P30A has one more feature that takes care of this. The P30A is fully balanced all the way through. This means you have two separate amplifiers, volume controls, and SoundEngine modules per channel. With this design, almost all leftover distortion is canceled out, and what you are left with is a signal that is as close to the original source material as possible.

Connections

The P30A offers a wide array of inputs and outputs. It features 2 balanced (XLR) and 3 unbalanced (RCA) inputs and a fixed level Home Theatre input that allows you to integrate it into a Home Theatre system. This input can also be configured to act as a normal input. On the other end you have one balanced (XLR) and two unbalanced (RCA) variable outputs that are all active, allowing you to connect several devices at the same time. One of the unbalanced RCA outputs can even be configured to be a fixed volume output. The P30A also has a 3,5 mm IR-direct input and a 12V trigger output connector. When you add it all up you get a highly versatile, extremely quiet, and natural sounding preamplifier that can be the heart of any high-end audio system. You get the P30A - A truly brilliant conductor of all music.
