Hydra

About the Hydra

The Rogue Audio Hydra is a tube/Class D hybrid power amplifier that integrates the smooth, organic sound of tubes with the dynamics and efficiency of Class D solid state technology. It features a triode tube front end combined with a Class D Mosfet output section, delivering 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms. The amplifier is designed with massive linear power supplies, large high-performance toroidal transformers, and a heavy 2-ounce copper circuit board for superior performance and reliability. It includes balanced (XLR) and single-ended (RCA) inputs, heavy-duty gold-plated binding posts, short circuit protection, standby circuitry for solid state components, and a slow start circuit to extend tube life. The Hydra runs cool, requires no tube biasing or regular maintenance, and is available in black or silver finishes. It measures 18" W x 15" D x 5.5" H and weighs 34 lbs. The amplifier is fully tested, burned in, auditioned, and comes with a 3-year limited warranty (6 months on tubes).
