AUDIO-GD HE-2 MK3 Power Amplifier Silver

With the HE-2 MK3, Audio-GD offers a pair of massive mono power amplifiers, for the integration of a high-end dual mono HiFi amplification system capable of producing 500W of power at 4Ω per channel, including 30W in pure Class A. This pair of amplifiers features a regenerative power supply as well as ACSS, Linear Fidelity and Non Negative Feedback technologies, contributing to a more transparent sound reproduction with very low distortion levels.

Audio-GD HE-2 MK3: Regenerative power supply

The power supply for Audio-GD's HE-2 MK3 is based on a set of 4 transformers per unit, 3 of which are regenerative, making a total of 8 transformers for a total of 2,000 W and an electrical capacity of 260,000 uF. The main advantage of the regenerative transformers is their ability to "self-power". In fact, this type of power supply has the ability to act as both a source and a load of current. In this way, these transformers can use excess energy not used by the system to feed it back into the system, thereby limiting the device's actual power consumption. Furthermore, the power supply stage of the HE-2 MK3 has a very high input impedance to avoid mains disturbance, and a fast, low impedance, high linearity output, making it a high quality power supply.

HE-2 MK3, Audio-GD : Linear Fidelity & Non Negative Feedback

Finally, for its HE-2 MK3 dual mono amplifier, the brand incorporates Linear Fidelity technology in the output circuits and Non Negative Feedback in the amplifier as a whole. This special design produces a linear response curve and a very low level of distortion, for extremely transparent sound reproduction, whatever the output level and frequency reproduced.
