18 Figure 17 The MC207 can easily drive 4 ohm speakers, with their high current demand. Additionally , the MC207 can be used with 8 ohm speakers, and deliver equal power . McIntosh’ s new DPM TM design enables it to run on higher voltage rails when connected to less current-hungry 8 ohm speakers and still deliver 200 watts. The power penalty usua[...]
