The Ideal Compact Partner for Your Flat-Screen Display

Movies and games look great on today's widescreen TVs. But let's face it, the audio from your typical flat-panel display leaves a lot to be desired. That's where the HTX-22HDX steps in. In its basic 2.1-channel configuration, the HTX-22HDX gives you a combo subwoofer and A/V amplifier plus two front speakers for stunning mid- and high-range audio. Connections? Check. Three HDMI® 1.4a inputs let you hook up a Blu-ray player, console, and cable/sat tuner. HDMI 1.4a is not only compatible with upcoming 3D video, it also lets you run an Audio Return Channel from your display's tuner back to the amplifier. Audio processing? Check. The HTX-22HDX handles HD formats from DTS and Dolby; employs quality Burr-Brown DACs for all channels; and includes Onkyo’s very own Theater-Dimensional. The latter creates an immersive and convincing surround effect through just 2.1 channels. Meantime, a new on-screen display makes it easier to adjust settings on the fly, so you can get back to the action sooner.

HDMI® Support for 3D Video and Audio Return Channel

The three HDMI inputs on the HTX-22HDX 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. The HDMI implementation on this model supports both 3D video and an Audio Return Channel, along with numerous
high-resolution formats. 3D video brings exciting possibilities to home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible TVs now on the market. Meanwhile, the Audio Return Channel allows audio content received directly by your HDTV’s tuner to be sent “upstream” via HDMI to your A/V component, without the need for a separate S/PDIF audio cable.

Decoding of High-Definition Surround-Sound Codecs

The HTX-22HDX 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. These codecs, previously available only on mid-range and high-end receivers, take advantage of the high data capacity of the Blu-ray format.

Immersive Surround Sound from Just Two Speakers

Onkyo’s Theater-Dimensional circuitry streamlines the conventional surround-speaker set-up by allowing you to experience the excitement of surround sound from as few as two standard speakers. What’s more, it also offers multi-speaker modes that you can use if you augment the HTX-22HDX with Onkyo’s optional SKS-22X center and surround speaker package. To save space, you can place up to five speakers beside the TV and still enjoy impressively realistic virtual surround sound.
