Driving Home Theatre with Pinpoint Accuracy, Potent Power and Multi-Entertainment Options

To create an AV home theatre receiver of exceptional quality, the challenge lies in incorporating the delicate processing circuits and amplifier components into the same chassis. When they both draw on the same power source, the amplifier dominates at peak moments. In a good design, it all works smoothly-as with the THX Select2 certified TX-SR804 7.1-channel AV surround home theatre receiver. You have video switching and up-conversion through HDMI (version 1.1) and component video enabling an effortless, high-bandwidth transfer of video and audio signals to the latest HDTV displays. Also, the inclusion of a Time Base Corrector (TBC) will effectively prevent any picture deterioration caused by timing inaccuracies. With numerous other features that help the TX-SR804 to stamp its class-Wide Range Amplifier Technology (WRAT), Vector Liner Shaping Circuitry (VLSC), multizone playback with a 12 V trigger, a wide-ranging crossover adjustment, RS232 & IR connectivity and iPod integration-this receiver stands out for its seemless, powerful functionality.

Onkyo TX-SR804

Key Features

  • HDMI and Component Video Up-conversion for HDTV Connectivity with Video Switching Capabilities.
    As the most advanced interface for transporting both uncompressed high definition (HD) video and uncompressed multi-channel audio in all HD formats including 720p, 1080i and 1080p, HDMI has become the most desirable connectivity option for home entertainment. This is superbly demonstrated with the TX-SR804. Its two HDMI (version 1.1) inputs will receive pristine video from HDMI-enabled components like DVD players or set-top boxes for a single-cable output to a display device with an HDMI or DVI connection. If that's not enough, it'll also up-convert any other source connected by component, S-Video or composite connections. In effect, you have the power to accommodate all your entertainment needs, from digital recording to spectacular gaming. And if your HDTV doesn't have HDMI capability, or you have yet to take the plunge, you can use the HD-quality component video connections (also with up-conversion) to get the best video images available.
  • THX Select2 Certified and THX Surround EX.
    With THX Select2 certification, the TX-SR804 demonstrates that it has met the rigorous design and performance standards set by THX. For the end user, it enhances the overall system's ability to accurately present movies the way they were mixed by the filmmaker on the dubbing stage and its additional THX listening modes enhance playback performance of music, movies and video games. Furthermore, its Adaptive Speaker Array (ASA) technology optimizes playback of multi-channel movies, music and video games. THX Select2 also includes the THX Surround EX decoder, which enables sound mixers to encircle the audience with 360-degree pans and more realistic fly-over and ambient sound effects.
  • Vector Linear Shaping Circuitry (VLSC) for All Channels.
    The TX-SR804 incorporates Onkyo's VLSC, which employs a unique D/A conversion circuit to mitigate the effect of signal noise. As noise is magnified during the conversion process, even minimal amounts of noise can adversely affect audio quality. With VLSC, data is converted between the sampling points and these discrete sampling points are joined with analog vectors in real-time to produce a smooth output wave form. The result - a noiseless, smooth analog signal based on the digital source.
  • Access to the Most Advanced Surround Sound Formats.
    The TX-SR804 has the onboard codecs - Dolby Digital EX, Dolby Pro Logic IIx, DTS-ES, DTS 96/24 and DTS Neo:6- to effectively reproduce stereo and multichannel sources in enveloping 6.1 or 7.1 surround sound. By connecting an HD-DVD or Blu-ray Disc player with 5.1- or 7.1-line level outputs to the TX-SR804's 7.1-multichannel inputs, you will be able to enjoy the full potential of high-definition audio formats like Dolby Digital Plus, Dolby True HD, DTS-HD and Master Audio.
  • Multiroom Playback Capabilities through Powered Zone 2 with 12 V Trigger.
    Powered Zone 2 gives you the option of different sources throughout your home. With the Powered Zone 2 function, you can enjoy one input source in the main room and a different source in another room through two different connection methods: using a receiver/integrated amp in Zone 2 (automatically activated by a 12 V trigger) or a pair of speakers in Zone 2. In the former method, you can enjoy 7.1 surround sound in the main room and play a different stereo source in Zone 2. With the latter method, you can use 5.1 surround sound in the main room and play a different stereo source in Zone 2.
  • Independent Crossover Adjustment for Bass Management.
    With the TX-SR804's crossover adjustment for bass management, you can independently set the frequency of your front, center, surround and surround back speakers at 40/60/70/80/90/100/120/150/200 Hz giving you greater scope to match different speakers and subwoofers to your system.
  • RI System and iPod Integration.
    The TX-SR804's Remote Interactive (RI) capability enables you to integrate different Onkyo components for control through one remote. Also, you can simply connect the iPod to the TX-SR804 through the Remote Interactive Dock for the iPod. The latest Remote Interactive Dock offers you onscreen menus, remote control, recharging capacity, and even photo/video playback.
