Like other high-quality McIntosh power amplifiers, the MC205 incorporates the newly developed McIntosh Dynamic Power ManagerTM circuit, or DPMTM. This unique circuit allows the MC205 to deliver its full power into a wide variety of loudspeaker types. DPMTM allows the MC205 to be optimized for whatever speakers are used. Unlike other high-current designs, the MC205 delivers the same 200 watts per channel into both 4-ohm and 8-ohm loudspeakers. The Dynamic Power Manager automatically controls and optimizes the power supply’s voltage and current balance, delivering higher voltage that 8 ohm speakers require, and automatically adjusting for current-hungry 4 ohm speakers. Furthermore, a new “smart” circuit optimizes amplifier characteristics for the impedance of the speakers connected automatically, always delivering the full amplifier.
