With its 5.5-kilowatt power supply feeding nearly 100 output devices, the Relentless Mono Amplifier easily delivers 1,500 watts into 8 ohms—and when connected to a 220-volt or greater AC mains outlet, it doubles its output to 3,000 watts into 4 ohms and 6,000 watts into 2 ohms. This power output is maintained with the same musical composure at full power as it is at 1 watt.
