ONKYO TX-SR313 5.1-Channel 3D-Ready Home Theater Receiver

3D Video and Audio Return Channel via HDMI
Four HDMI inputs on the TX-SR313 allow seamless integration of high-definition devices such as Blu-ray players, cable/satellite tuners, and gaming consoles. HDMI implementation on this receiver also supports an Audio Return Channel, allowing TV audio to be sent upstream to the A/V receiver. That means you can enjoy television programs in magnificent Onkyo sound. HDMI also supports 3D video and other popular high-resolution formats.

Direct Digital Connection: The Cleanest Your iPod Can Sound
The front-panel USB port lets you play MP3 and AAC stored in an iPod/iPhone, and MP3, WMA, AAC, and FLAC audio files stored on a flash-memory device, and you can use the system's own remote for track selection and playback. Your music will sound much cleaner and clearer, as the audio signal is transported in digital rather than analog form through the direct digital connection.

ONKYO's Proprietary WRAT Technology
WRAT improves the fidelity of amplified audio and reduces noise across the frequency range, guaranteeing a well-balanced performance even with the most dynamic soundtracks. It achieves this by employing a low negative-feedback amplifier design; using "closed" ground-loop circuitry to cancel noise from individual circuits; and by ensuring high instantaneous-current capability. Also Onkyo uses discrete transistors, which help guarantee a consistent, stable supply of current to the speaker system for an open and assured performance.

Easy Access For Settings Changes
The TX-SR313's overlaid On-Screen Display (OSD) feature makes changing the settings on your A/V receiver quick and easy. On-screen set-up menus appear over the video image you're watching so you can adjust the settings immediately, without having to stop the program and switch to a different screen to access menus..
