About the H30A
The Hegel H30A is a versatile power amplifier that can operate in both mono and stereo modes. It is capable of delivering over 1100 watts into an 8-ohm load in mono mode and 300 watts per channel in stereo mode at 8 ohms. The amplifier features dual 1000 VA toroidal transformers and a large power bank of 270,000 μF capacitors, ensuring stable operation even with loads as low as 1 ohm. The output stage uses 56 high-speed, ultra-low distortion bipolar transistors, providing excellent control over demanding speaker loads. The input stage incorporates hand-matched FET transistors to minimize harmonic distortion, and Hegel's patented SoundEngine2 technology actively corrects for distortion in real-time, ensuring a smooth and natural sound. The H30A supports both RCA unbalanced and XLR balanced inputs and is designed to handle a wide range of musical genres with precision and power.
