Onkyo's mission is to deliver outstanding audio and video quality to your home, no matter what budget you're on. With the 7.1-channel TX-SR508, you get an entry-level home theater centerpiece built to unleash the potential of your favorite entertainment sources. The TX-SR508 arrives brimming with processing and connectivity features previously unheard of at this level. Four 3D-ready HDMI 1.4a inputs for connecting your high-definition sources, studio master-quality HD audio formats from Dolby and DTS, Dolby Pro Logic IIz for new surround-sound possibilities, powered Zone 2 and bi-amping for more speaker flexibility, and a Universal Port and front-side input for connecting peripherals and portable devices. Meanwhile, Audyssey volume and equalization technologies ensure comfortable listening and a room-fitting soundstage. Underpinning it all is decades of Onkyo amplifier expertise in the form of WRAT (Wide Range Amplifier Technology) and a high-current, low-impedance drive.
The TX-SR508's four HDMI inputs let you simultaneously connect high-def sources such as a Blu-ray player, a gaming console, and a cable/satellite tuner. 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 HDTVs on the near horizon--the TX-SR508 gets you ready for this next generation of content at a surprising value.
The Onkyo TX-SR508 A/V receiver can decode Dolby® TrueHD and DTS-HD Master Audio™—two lossless formats that enable delivery of a bit-for-bit soundtrack identical to the studio master track. Previously available only on mid-range and high-end receivers, now you can take full advantage of your Blu-ray movies for a true cinematic audio experience. The TX-SR508 also handles Dolby® Digital Plus and DTS-HD High Resolution Audio™.
Beginning with the TX-SR508 all 2010 Onkyo A/V receivers come with a suite of Audyssey technologies that help create the most suitable listening environment for your home.
Changing your A/V receiver's settings is now more seamless than ever, thanks to the TX-SR508's new overlaid graphical On-Screen Display (OSD) feature. Simply press the Home button on the included remote controller, and semi-transparent graphical set-up menus appear overlaid on the video image you're watching. This means you can adjust the settings immediately, without having to switch back and forth from a blank screen background.
A proprietary Universal Port located on the rear side of the Onkyo TX-SR508 lets you connect an optional UP-A1 Dock for iPhone/iPod or UP-HT1 HD Radio Tuner (both sold separately). If you have both peripheral devices, they can easily be "daisy chained" via an input on the UP-HT1. 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.
The cornerstone of any Onkyo A/V receiver, WRAT supports high-quality audio reproduction of the latest high-definition A/V formats. It comprises three key elements: A low negative feedback design for cleaner audio across the frequency range; a closed ground-loop circuit to cancel individual circuit noise and keep the ground potential free of distortion; and a high instantaneous current capability to handle speaker reflex energy and impedance fluctuations.
With Powered Zone 2, you can enjoy surround sound entertainment in the main room, while playing back a different stereo source in a second zone equipped with a pair of speakers. Alternatively, you can use the Zone 2 line out to send an unamplified audio signal to an amplifier (and speakers) in the second room.
These four gaming modes create an audio experience with more realism and impact. You can select from Rock, Sports, Action, or RPG (Role Playing Game) modes to match your gaming content.
While MP3 or AAC files may sound fine on a portable digital player, the limitations of these compressed files can be exposed when played back through a home entertainment system. Onkyo has designed onboard Music Optimizer technology to improve the quality of compressed audio signals. Compressed music loses a substantial amount of bit information at higher frequencies, so the Music Optimizer technology works to overcome this limitation and enhance audio quality.
Onkyo's TX-SR508 offers compatibility with optional tuners for both HD Radio and SIRIUS Satellite Radio. HD Radio broadcasts your favorite AM and FM stations digitally, with none of the hiss, distortion, or station drop-off of analog radio. SIRIUS provides exclusive access to over 130 channels of commercial-free music, sports, news, talk, and comedy.
Onkyo's exclusive Theater-Dimensional circuitry takes the complexity out of conventional surround-sound set-ups and lets you experience the excitement of surround sound from as few as two ordinary speakers. Want more? Theater-Dimensional's unique multi-speaker modes let you place up to five speakers conveniently by the TV, for the most realistic virtual-surround sound possible.
Onkyo A/V receivers offer integrated system control with certain HDMI-compatible high-definition displays, DVD and hard-disk recorders, and Blu-ray Disc players. With one remote control, you can control functions such as Standby, Volume, and Direct Change.
If you have an iPod® or other MP3 player, you can connect it to the TX-SR508's front panel for quick and convenient audio playback. Your player's compressed digital music files can then receive a quality boost from the receiver's Music Optimizer technology.

I purchased a used receiver said to be in good shape. The sound quality is excellent, but it was unusable for my purpose because it could not pass the HDMI out. Read morePublished 16 months ago by A.Firebrand

Would never consider anything else for sound. Whenever this gives out (I use it quite a bit), another Onkyo it would be.Published on May 25, 2013 by KYLE
