Mac Audio Edition S Four

Four-channel amplifier, stable at two ohms

The 4-channel amplifier from the Edition S range is equipped with an efficient MOSFET power supply and delivers a maximum power output of 250 watts on 4 channels with absolutely stable operation at 2 ohms. The powerful amp is fitted with a channel mode selector switch and offers bridge or tri-mode operation. The combination of high-quality potentiometers with metal axes, selected internal electronic components and the multi-part aluminium heat sink with enlarged surface structure for optimum heat dissipation guarantees the highest performance level. The hairline finish and the stylish Mac Audio sticker on the top of the amplifier give the Edition S Four a sophisticated exterior.
