In terms of the evolution of home entertainment systems, the Onkyo TX SR805 7.1-channel 300 watt receiver stands as a formidable device. This receiver boasts 1080p, high-definition video and broadcasts with THX Certified Ultra2 lossless surround sound. This receiver offers a spectacular gaming experience with stunning motion and graphics, and also has portable satellite radio programming. Bundling all of this potential, the device includes an easy-to-navigate interface and a pre-programmed learning remote that enables comprehensive control over movies, music, broadcasts, and gaming. This receiver goes even further by providing you with sophisticated room-correction technology, multi-zone capabilities, powerful bi-amping, and dual push-pull amplification.Onkyo chose to incorporate numerous input source options with the TX-SR805 receiver. This is because of the diverse array of sources such as computer-based lossless audio formats and vinyl. On the visuals side, the increasing range of possible video resolution has broadened the potential ways for high-quality content to be stored and transmitted. The Onkyo TX-SR805 is ideally suited for such an environment. With seven channels, it delivers a true surround-sound home theater experience and drives each speaker with a powerful 300 watts. That is more than enough to host a party in a large room. The clarity and soundstage of the ensuing audio are excellent and stay true to the source, reflecting Onkyo's commitment to letting better source signals speak for themselves.The video side of this Onkyo 300-watt receiver is just as impressive. Not all video content is in 1080p-plus format, like that in DTS-HD for Blu-ray. For people with extensive movie collections that include DVDs, you still great imaging and sound through the speakers. That is why the SR805 includes upscaling to boost those older sources and update playback technology. That is an important feature because many older movies are not optimized for newer TVs, so they are often not as visually sharp. The upscaling resolves the problem. The receiver is compatible with several different a/v inputs, providing quality output each time.Special features include a radio tuner with 40 preset stations and the ability to adapt audio settings separately to each individual room component for the best sound. It offers Burr Brown onboard DACs, a detachable power cord for safety and ease of use, and the ability to push those 300 watts through each of its 7 channels. The right set of speakers takes full advantage of that wattage to create detailed, clear high-volume audio performance. A large HDTV capable of 1080p or greater resolution and HDMI connection refreshes the look of your older movies and TV shows. Onkyo has designed and built these premium receivers with the intent of doing the best job they can of showcasing each and every source. All of this comes in a relatively small package that is easy to fit into your media console or other furniture.
