Product Description

Product Description

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.

From the Manufacturer

Made for iPod®/iPhone®

Onkyo receivers allow you to and play audio files stored on your iPod/iPhone or even a USB flash drive. The on screen display lets you see exactly what is playing. As the audio signals are played back in digital form, rather than analog, there is much less chance for signal degradation. Onkyo's exclusive Advanced Music Optimizer also compensates for lost bit information and improves the quality of compressed audio signals.
End result: Your music sounds cleaner and more faithful to the original.

3D and ARC

All Onkyo A/V receivers support the latest in 3D technology. Play 3D movies, games, and broadcast content in cinematic quality in your own home and be amazed by the realistic quality. The HDMI® inputs let you connect multiple high-def sources, such as a Blu-ray player, a gaming console, and a cable/satellite tuner. The HDMI output, on the other hand, lets you send a pristine signal to a compatible high-resolution display. Audio Return Channel allows audio content received directly by your HDTV’s tuner to be sent “upstream” via HDMI to your A/V receiver, without the need for a separate S/PDIF audio cable.

Change Your Receiver's Settings Seamlessly

Thanks to Onkyo's overlaid graphical on-screen display (OSD), set-up menus appear on top of the video image you're watching, so you don't have to switch to a blank screen background. Easily navigate intuitive menus to maximize all of the features and benefits of your Onkyo A/V receiver. The OSD and Graphical User Interface (GUI) both operate over HDMI, making excellent use of that versatile interface.
