Bringing both high-definition audio and video into an entry-level Onkyo A/V receiver for the first time, the TX-SR576 breaks barriers that were thought impregnable just a short time ago. Thanks to the TX-SR576s HDMI platform, this receiver stands out with three masterful high-def advantages: 1) The ability to switch three 1080p video sources; 2) The scope to handle enhanced Dolby Digital Plus encoded audio; and 3) The capability to integrate and operate compatible components from the leading consumer electronics brands. In recognition of the need for home theater to adapt to spacious living rooms as well as to cozy apartment spaces, the TX-SR576 features new Audyssey technologies that let you tailor surround sound to your home and ensure an enveloping soundscape, even at low volumes. When it comes to digital music, this receiver draws on Onkyos own technology to spark life into digital audio files such as MP3s.
