The most powerful (monoblock) of Lamm hybrid amplifiers. It is made in the form of monoblocks. The amplifier demonstrates the unique transparency and volume of the sound stage. The output stage on MOSFET high-speed field-effect transistors operates in class A/AB with a high quiescent current. The optimal quiescent current of the output stage for a particular load is selected using a switch with two positions: 1-6 ohms and 8-16 ohms. The 2.2 amplifier provides 220 watts of output power at 8 and 4 ohms in Class A (at the appropriate switch positions), 440 watts at 2 ohms and 600 watts at 1 ohm.
