TX-SR309 5.1-Channel 3-D Ready Home Theater Receiver
 

An Easy Entry Point into the World of Fully Immersive Home Theater

Continuing our mission to bring quality to every level of home entertainment, Onkyo presents the TX-SR309—an entry-level A/V receiver fine-tuned to power your system right out of the box. Set-up is simple and adjustments are easy, thanks to a new overlaid on-screen display. Also new at this level is PLL jitter-cleaning circuit technology to reduce distortion, and a front-panel USB port that provides a high-quality digital link to your iPod®/iPhone®. To get the best from your compressed audio files, the TX-SR309 employs Onkyo’s proprietary Advanced Music Optimizer. Naturally, the receiver also handles high-def, lossless audio in the form of Dolby® TrueHD and DTS-HD Master Audio™. These are carried by three HDMI® inputs that also support immersive 3D video content. And whether you’re gaming in 3D or not, you can choose from four customized audio modes to match your gaming content. It all adds up to one high-value proposition.

  • 4 DSP Gaming Modes: Rock, Sports, Action, and Role Playing
