600 Watts Stereo Analog Audio Amplifier 2 channel Class H Power Amplifier
HQ-2.6
No-compromise audio performance with improved efficiency
It is useful to expand Class AB amplifier technology with “Class H switching”, especially high output power amplifiers. This idea seems to be very simple at first sight. The AB amplifier is provided with an additional power supply unit operating with half the voltage. As long as the power amplifier does not require a high output level – which is the case for most applications, especially fixed installations – it is supplied by the lower operating voltage, thereby significantly reducing power loss.
