It boasts a robust build quality, cutting-edge technology, and exceptional sonic performance, and is a true centerpiece for any high-fidelity sound system.\u003c\/p\u003e\u003cp\u003eThe P-4600 delivers a robust 150 watts per channel into 8 ohms, doubling to 300 watts into 4 ohms. This ample power ensures it can drive demanding speakers with ease, faithfully reproducing even the most dynamic musical passages.\u003c\/p\u003e\u003ch3\u003eGroundbreaking technology\u003c\/h3\u003e\u003cp\u003eThe Accuphase P-4600 power amplifier utilises a sophisticated Class AB design that combines the best of both Class A and Class B amplification for a perfect balance of power, efficiency, and sound quality.\u003c\/p\u003e\u003cp\u003eAccuphase employs top-of-the-line components throughout the P-4600, including custom-wound transformers, high-grade capacitors, and meticulously selected transistors. This attention to detail results in exceptional audio clarity and accuracy.\u003c\/p\u003e\u003ch3\u003ePower amplification section with linear output characteristics\u003c\/h3\u003e\u003cp\u003eThe power amplification stage of the P-4600 features bipolar power transistors mounted directly to large heat sinks for highly efficient thermal dissipation. The devices are configured as a triple Darlington 4-parallel complementary push-pull circuit that is capable of doubling the rated output when the impedance is halved. In other words, it achieves a fully linear power progression of 90 watts into 8 ohms, 180 watts into 4 ohms, and 360 watts into 2 ohms. It can even supply loads as low as 1 ohm with 500 watts of power (music signals). The impressive damping factor of 700 means that the amplifier has ample leeway to drive any kind of loudspeaker.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eContinuous Average Output Power:\u003c\/strong\u003e Stereo operation - 500 watts per channel into 1 ohm, 360 watts per channel into 2 ohms, 180 watts per channel into 4 ohms, 90 watts per channel into 8 ohms.
