Description
Accuphase P-4600 Class AB Stereo Power Amplifier
Powerful, Refined, and Resolutely Musical
The P-4600 Class AB stereo power amplifier is built to exceed expectations, combining robust engineering with Accuphase’s signature musicality. Its 6-parallel push-pull power transistor output stage delivers 150 W into 8 ohms, 300 W into 4 ohms, and 450 W into 2 ohms. Backed by a remarkable signal-to-noise ratio of 125 dB and a high damping factor of 800, the P-4600 effortlessly drives demanding speakers with full control and finesse.
Precision Circuitry, Dynamic Performance
Engineered with the instrumentation amplifier principle and current feedback amplification, the P-4600 maintains extraordinary linearity and transparency across the frequency spectrum. The use of Balanced Remote Sensing and Accuphase’s MCS+ circuit further enhance stability, speed, and tonal realism. Every nuance is captured and amplified without compromise.
Elegant Design, Versatile Integration
Equipped with large, highly responsive analog power meters and protected by advanced speaker output circuitry, the P-4600 is as durable as it is precise. It supports both bi-amping and bridged configurations, offering flexibility for complex system builds. With its refined aluminum hairline chassis and superior damping feet, the P-4600 blends into any high-end audio system while standing out in performance.
