TX-SR577 B
The TX-SR577 rewrites the rules of affordable home theatre by combining superb video processing, convenient connectivity, and 7.1 channels of spectacular high-definition audio. With its four HDMI 1.3a inputs, the TX-SR577 lets you hook up, say, a Blu-ray Disc player, an HD set-top box, an upscaling DVD player, and a PlayStation® 3 gaming system. HDMI is also the conduit for the superb, master-quality audio of Dolby® TrueHD and DTS-HD Master Audio™. The very latest Dolby technology, Dolby® Pro Logic® IIz, gives you the option of incorporating front height channels to enhance the spatial sensation of music, movies, and video games. When it comes to balancing volume levels and customizing the multichannel soundstage to the dimensions of your room, the TX-SR577 employs a suite of intelligent Audyssey surround-sound listening modes. Rounding out this versatile A/V receiver is a rear-side universal port that lets you connect an optional Onkyo Dock for the iPod or Onkyo DAB+ Radio Tuner.
