Anthem STR power amplifier is the beating heart of a world-class 2-channel sound system. It delivers massive power generation, with audiophile-quality in a smart component. Designed, engineered, and crafted in Canada, the STR power amplifier delivers 400 Watts / channel into 8ohms with both channels driven, a massive 600 Watts / channel into 4ohms (both channels driven) and 800W in 2ohms, for a great performance.
Inside, the STR power amplifier uses two colossal transformers and multiple high-current output devices. Outside, its beautifully designed cosmetics, including a 7-inch graphic control display and secure, highly conductive audiophile connectors provide a great match to the STR preamplifier.
