Full Power Balanced
650Mc Monaural Power Amplifier
The Full Power Balanced 650Mc Power Amplifier is the most powerful amplifier in the Krell Full Power Balanced Series. It provides the monumental power output of 650 Watts into 8 Ohm, 1300 Watts into 4 Ohm, and 2600 Watts into 2 Ohm loudspeaker loads. It is built in limited quantities and by special order. The model for this power house came from a custom amplifier that C.E.O. Dan D’Agostino designed specifically to power large speakers like the Wilson Audio Grand Slam and the Martin Logan Statement as the front main speakers in his personal home theater system. Mr. D’Agostino was developing the Krell Audio + Video Standard Preamp/Processor at the time and needed an amplifier of unlimited power to get maximum output from his system.
