Hegel H400 - Dual Mono Integrated Streaming Amplifier

The Hegel H400 Integrated Amplifier is engineered to deliver exceptional audio quality while maximising efficiency and enhancing the user experience. Whether you are an audiophile or a casual listener, the H400 promises a remarkable listening journey.

The H400 is a Class AB amplifier, delivering 250W of power into 8 ohms, and is stable down to 2-ohm loads. With a remarkable damping factor of 4000, H400 ensures tight control over your speakers, providing precise and dynamic sound. H400's dual mono construction and symmetrical layout ensure superior sound quality.

The absence of an equaliser preserves signal integrity, while Hegel's SoundEngine 2 technology offers instant distortion correction during amplification. This results in a detailed, agile sound, delivering both punch and finesse while maximising power efficiency. Experience your favorite music with a new level of clarity and richness, as the H400 faithfully reproduces every nuance and detail.

The H400 incorporates many of the same advanced features found in the Hegel reference integrated amplifier, ensuring high performance and value. It includes the same Dual Mono design, the same robust streaming platform, and a high-quality bit-perfect DAC based on the one in the H600. These shared features mean that the H400 delivers similar high standards of sound quality and versatility, making it a remarkable choice for discerning listeners.

In-House Product Development

Every aspect of the H400 has been meticulously developed in-house with Hegel, ensuring unparalleled quality control and cohesive design. This streamlined approach eliminates unnecessary steps and complications, allowing Hegel engineers to focus on innovation and performance. By keeping development under one roof, Hegel guarantee that every component and feature is perfectly integrated, enhancing overall efficiency and reliability. This in-house development strategy also allows for faster implementation of new features and improvements, ensuring the H400 remains at the forefront of audio technology.

Built from high-quality materials and components, the H400 is designed for durability and reliability, ensuring a long life, and minimizing the need for frequent maintenance. The SoundEngine 2 technology makes the H400 energy efficient, consuming minimal power while delivering top-tier performance. This technology, and the amplifier's auto standby feature, reduces energy waste and environmental impact without compromising sound quality.

Design / Inputs and Outputs

Designed with simplicity and intuitive operation in mind, the H400 features a sleek, minimalist front with two multifunctional knobs for source selection and volume control. The knobs can also be pressed to mute, pause, or navigate the device menu. The central display is clear and easy to read from a distance, showing only essential information. To maintain a clean and uncluttered appearance, the power button is discreetly located underneath the amplifier. This thoughtful design ensures that nothing distracts from the beauty of your audio setup.

The H400 offers a comprehensive range of analogue and digital inputs, ensuring seamless compatibility with various audio sources. Its impressive power, detail, and control means you can connect any speaker, even those very hard to drive. With automatic signal detection, the H400 instantly recognizes connected digital audio sources and switches to the correct input, eliminating the need for manual selection.

All inputs can be set at a fixed high volume, enabling the use of home theatre preamps and multi-room devices. It even has a TV remote function that lets you use your TV remote to control the amplifier, making your home entertainment setup more intuitive and user-friendly.
