Thanks to its proven Class AB technology, it delivers dynamic, detailed sound with excellent control across the entire frequency spectrum. The versatile configuration options allow for the operation of front and rear speakers as well as bridge mode for high-performance mid-bass drivers or smaller subwoofers\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp data-start=\"512\" data-end=\"1133\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eThe specially developed A-Star heat sink design ensures efficient heat dissipation and supports reliable continuous operation even under higher power demands. For quick and safe setup, the amplifier features an integrated CLIP indicator that assists with proper level adjustment, as well as a high-level input with an automatic turn-on (ATO) function for modern factory radios without a remote signal. Comprehensive protection circuits against overheating, short circuits, and DC voltage further enhance operational safety\u003c\/strong\u003e\u003c\/span\u003e.\u003cbr\u003e\u003cbr\u003e \u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-section-id=\"vdeyho\" data-start=\"1135\" data-end=\"1155\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTechnical Specifications\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul data-start=\"1157\" data-end=\"2087\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1efud0\" data-start=\"1157\" data-end=\"1186\" style=\"font-weight: bold;
