Onkyo 7.1 HDMI Up Conversion A/V Receiver TXSR674
To move to a level beyond purely functional home theater, the TX-SR674 gives you everything you need for audibly powerful, visually expressive home entertainment. The first consideration should be the essentialslike rock-steady amplifier power and performance through Wide Range Amplifier Technology (WRAT) and the cleanest audio signals generated by Vector Linear Shaping Circuitry (VLSC). And with HDTV in mind, the TX-SR674 also offers High-Definition Multimedia Interface (HDMI) and connectivity with the latest high-definition disc formats. Capping it off with Audyssey 2EQ room acoustics correction technology, the TX-SR674 stands out as one of the more complete A/V receivers in its class.
- HDMI 2 Input / 1 Output, 1080p bandwith - ready for next generation DVD players
- Auto Speaker Calibration with Audyssey 2EQ - Creates an optimal listening area, not a point - perfect for families
- Video Upconversion to HDMI with deinterlacing - ensuring your video looks the best on the newest tv's
Key technology Features:
192 kHz/24bit AD Converters: Costly, extremely powerful digital-to-analog converters , that not only boast a dynamic range of 120 dB, they process information faster and are virtually resistant to clock jitter, to ensure the best possible performance from DVD-Audio, DVD-Video and audio CD.
Dolby Digital EX / Pro-Logic IIx: Home theater realism reaches new heights with the creation of Dolby Digital EX. By adding a matrix-encoded surround back channel derived from the existing discrete left and right surround channels, the lack of rear surround in 5.1 channel is eliminated. The result - a fuller 360º experience is created even from 5.1-channel DVD releases. Best results are obtained when Dolby Digital EX is used with movie soundtracks recorded with Dolby Digital Surround EX. Pro-Logic IIx is the latest improvement on the original Pro-Logic and subsequent Pro-Logic II standards. Pro-Logic IIx adds post-processing to 5.1 channel and stereo signals, creating a realistic 7.1 channel surround environment from 5.1 channel movies and stereo sources, such as CD, Tape, FM Radio.
NeuralSurround: Neural Surround represents the latest advancement in surround technology developed for music and is adopted by XM Satellite Radio for digital radio broadcast of surround recordings and live events in surround sound. Neural Surround employs psychoacoustic frequency domain processing which allows delivery of a more detailed sound stage with superior channel separation and localization of audio elements. System playback is scalable from 5.1 to 7.1 multi channel surround playback.
VLSC (Vector Linear Shaping Circuitry): Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but cant remove it completely. Previously only found on our high-end components, VLSC (Vector Linear Shaping Circuitry) employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analog vectors in real-time to produce a smooth output wave form. The result a virtually noiseless, smooth analog signal based on the digital source to bring out even the most subtle of nuances in your music, movie soundtracks and even MP3s.
XM Ready: The XM "Connect-and-Play," is a revolutionary technology platform designed to integrate XM into virtually any home or portable consumer electronics entertainment device. By matching XM Ready® audio systems with a simple, elegant antenna/receiver, getting XM becomes even easier for home audio listeners.
CinemaFILTER: The tonal balance of a film soundtrack can be edgy and bright when played back over audio equipment in your homethis is because film soundtracks are designed to be played back in large theaters, using commercial equipment. Onkyo has developed its own solution that restores the correct tonal balance of a movie soundtrack in the smaller environs of your home theater.
DTS-ES 96/24 Neo6: There are two DTS®-ES (Extended Surround) formats: DTS®-ES Discrete 6.1 and DTS®-ES Matrix 6.1. The DTS®-ES Discrete 6.1 format is, as the name implies, a 6.1-channel system with a discrete back surround channel, while DTS®-ES Matrix 6.1, like Dolby® Digital Surround EX, provides a matrix-encoded back surround channel. Theres also DTS® Neo:6, which derives a 6-channel surround output from a stereo soundtrack, and regular DTS®, which, like Dolby® Digital, is a discrete 5.1-channel system, but which uses less compression than Dolby® Digital. Receivers carrying the "96/24" designation are able to decode a new high-resolution audio format, DTS-96/24. This breakthrough allows for high quality, 5.1 channel audio encoded at 96kHz/24-bit resolution to be stored on a DVD-Video disc (or the DVD-Video portion of a DVD-Audio disc). This format is compatible with all DVD players, with those able to pass a 96kHz signal providing the highest quality output (DTS-96/24 is also backwards compatible with older 48kHz DVD player models).
HDMI Video Upconversion: Converts incoming composite, S-Video signals (like a VCR to S-Video equipped TV), and component signals all the way to HDMI on most models.
Powered Zone 2: By dedicating a pair of channels on receivers with this capability, you dont need an external amplifier to enjoy an independent stereo audio source in a remote room. For example, on higher-end models this allows for a full 5.1 channel movie to be enjoyed in the home theater, while simultaneously sending a song from a CD (or other source) to speakers in another room.
WRAT (Wide Range Amp Technology): Imagine turning up the volume and filling your entertainment room with noise-free, impressively powerful, true-to-life sound. That's the benefit of Wide Range Amplifier Technology. Originally developed for our most expensive high-end amplifiers to handle the sonic demands of today's digital age, you'll now find WRAT even in our lowest-priced A/V receivers. The WRAT family of technologies includes a broader frequency range with lower noise entering the signal path perfectly suited for new high resolution DVD-Audio and SACD formats.

Sound and picture are better than before. A comination of a great receiver and HDMI in place of component. I had two issues in the set-up.
1. I only have five speakers (plus sub) and no plans for seven. I tried to run the Audessy auto set-up and it kept failing. I called Onkyo and was told by tech support that I needed to attach my "rear" speakers to the "surround" inputs. I did, and the auto-set up then ran perfectly. Tech support was great. My only complaint is that the documentation didn't make this clear in the first place.
2. The Samsung unit is their newest combo recording DVD/VCR -- the DVD/VR357. I bought it to replace an older, non-HDMI DVD as well as a VCR that had given up the ghost. I connected it to the receiver via HDMI and could not get a clean signal onto the TV. I figured it might be a function of the HDCP protection. I hooked up component cables along with an optical audio cable and it worked fine. However, this was not my preferred way of connecting. Samsung tech support said it could be a bad cable, but more likely it was a function of the copyright function and/or inability of the components to make a proper "handshake." Their suggestion was to plug the Samsung directly into the TV instead of the receiver. Fortunately, the TV has a spare HDMI input but it kind of defeats my original purpose to do this.
Overall, happy. I am going to try another HDMI cable from a different supplier to see whether that works. If not I will just leave as is.
Added information: Tried a different HDMI cable. Didn't work either. It appears you cannot run HDMI out of a DVD player, into the Onkyo, and out to the TV via HDMI. Component works fine, though. When I break down and buy an HD DVD player or Blu-Ray I will just run it directly to the TV.
Update-I've now had this for 2 years. I run a Panasonic BR and cable HD-DVR into the HDMI inputs. I upgraded the sub-woofer to a Yamaha powered sub-woofer. I use the remote speaker outputs for audio in the rest of the house.
I would like more HDMI inputs. But I still love that this is a switching unit for HDMI. BUT...the picture goes blank every once in a while for a few seconds. Other than that, it's still a great unit.
