TX-SR308

5.1-Channel Home Theatre Receiver
The Ideal Choice for Newcomersa High-Value Home Theatre Centerpiece
At the budget-conscious end of the home entertainment spectrum, youre looking to maximize performance and features without putting undue strain on your finances. At Onkyo, we get it. Thats why weve redefined the entry-level A/V receiver once more, with the high-value TX-SR308. Not only is it ready for the 3D videothanks to its HDMI 1.4a specificationbut it also handles high-definition lossless audio codecs from Dolby and DTS. Advanced A/V processing on a bedrock of classic Onkyo engineering is complemented by a bevy of convenient features: a new overlaid On-Screen Display for easy adjustment of settings; a Universal Port for single-cable connection of peripherals; and a front-panel audio input for direct connection of iPods and other MP3 players. With the TX-SR308, you get an affordable home theatre centerpiece ready to drive the latest high-def entertainment sources.
HDMI 1.4a Support for 3D Video and Audio Return Channel
HDMI has fast become the cable of choice for connecting todays A/V components. The three HDMI 1.4a inputs on the TX-SR308 let you simultaneously connect high-def sources such as a Blu-ray player, a gaming console, and a cable/satellite tuner. A single output then sends a pristine signal to your connected high-resolution display. As the latest version of this connector, HDMI 1.4a adds the exciting possibilities of 3D video and an Audio Return Channel. 3D video is the next big thing in home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible TVs on the near horizon. The TX-SR308 also offers the convenience of an Audio Return Channel via HDMI. Audio content received directly by your HDTVs tuner can be sent upstream to your A/V receiver, without the need for a separate S/PDIF audio cable. designed to accompany high-definition video delivered via disc media, broadcasts, and online content. DTS-HD High Resolution Audio, meanwhile, offers a greater bit rate, a higher sampling rate, and more channels than the core DTS technology.
Universal Port for Single-Cable Connection of Optional Onkyo Dock for iPhone/iPod
A proprietary Universal Port located on the rear side of the TX-SR308 lets you connect an optional UP-A1 Dock for iPhone/iPod. A key advantage of the Universal Port is that it accepts video and audio signals through the same cable that sends a power supply from the receiver to the devices. Net result: more connectivity, less cable clutter.
Convenient Overlaid On-Screen Display via HDMI
Changing your A/V receivers settings is now more seamless than ever, thanks to the TX-SR308s new overlaid On-Screen Display (OSD) feature. On-screen set-up menus appear overlaid on the video image youre watching. This means you can adjust the settings immediately, without having to switch back and forth from a blank screen background.
Decoding of High-Definition Surround-Sound Codecs
The TX-SR308 can decode Dolby TrueHD and DTS-HD Master Audiotwo lossless formats that enable delivery of a bit-for-bit soundtrack identical to the studio master track. These codecs, previously available only on mid-range and high-end receivers, take advantage of the high data capacity of the Blu-ray format. The TX-SR308 also handles two lossy audio formats: Dolby Digital Plus and DTS-HD High Resolution Audio. Dolby Digital Plus is
Four Game Modes for More Realistic Action

Music Optimizer to Enhance Compressed Digital Music Files
While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of highfrequency bit information is lost during the filecompression process. To counter this, Onkyo has designed onboard Music Optimizer technology to compensate for lost bit information and improve the quality of compressed audio signals.
