Edition S Four LTD.

Four-channel amplifier, stable at two ohms

Up to 300 watts maximum power output on each of 4 channels is possible with the Edition S Four Limited. The stable operation at 2 ohms is achieved by the efficient internal electronics and the reliable MOSFET power supply. Stylish looks and perfect heat dissipation are guaranteed by the aluminium heat sink with a hairline finish.

Four-channel amplifier, stable at two ohms

1000 watts on 4 channels not enough? All that remains then is the Edition S Four Limited which, with a maximum power output of 1200 watts, even outshines the Power-House Edition S Four. Cleared for stable operation at 2 ohms, the 4-channel amplifier with MOSFET power supply and optimum temperature management thanks to the aluminium heat sink with an enlarged surface delivers high-end performance in a very reliable way. In addition, the Edition S Four Limited is safeguarded against short circuits, DC offset and overheating by a protective circuit. A channel mode selector switch, low-level outputs and operating display with dual colour LED are also provided, of course.
