It features an array of eight high-voltage electrolytic capacitors that smooth out the rectified AC from the transformer into stable DC power. This board is critical for maintaining high damping factors and providing the instantaneous current required for deep, impactful bass transients without causing voltage drops.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eKey Features \u0026amp;
