Experience the top of the line Marantz AV Receiver range with the SR7011. Surround yourself in thrilling 3D surround sound with the most complete immersive format including Dolby Atmos, DTS:X, and Auro 3D (via paid upgrade). All three codecs are able to drive overhead speakers for a true 3D sound experience. And thanks to the receiver's 9 high quality amplifier stages, each providing 125 W of pure Marantz power and finesse, you can drive a full 5.1.4 home cinema setup without the need of additional external amplifiers. The SR7011 features high grade audio components that have been carefully selected. The whole internal circuit further enhances audio quality by delicately handling all signals via the Marantz-own HDAMs (Hyper Dynamic Amplifier Module) in Current Feedback topology before passing them on to the power stage to fire up the connected speakers.
