This is the typical architecture for the output Power Stage of the Harman Kardon Signature integrated Amplifiers.
The architecture of Harman Kardon’s Signature Series amplifiers is a combination of high-current, wide-bandwidth design, and careful attention to the physical and electrical layout of components. By focusing on discrete amplification, dual-mono designs, and high-quality power supply units, Harman Kardon created a series of amplifiers that were both powerful and refined, offering high-end audio performance with excellent precision and durability. This architectural approach is key to the Signature Series’ ability to deliver natural, detailed, and dynamic sound, whether used in a stereo or home theater system.
Output power = 180 Wrms @ 8 Ohms
