Class H Power Analog Audio Amplifier 1800 Watts Stereo Amplifier 2 channel
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.
HQ amp is the the production of high-performance power amplifiers. The innovative 3-stage Grounded Bridge Class H Technology with “floating" switching power supply unit offers very high and stable output with extreme high efficiency on an extremely high performance level at minimum weight. HQ amps are ideal for driving professional touring, high-end Concert-Sound and Pro-Sound applications.
