Key technology Features:
HDMI: HDMI (High-Definition Multimedia Interface) This high-bandwidth interface supports not only brilliant digital video, but digital audio as well. Up to 5 Gbps of datamore than twice whats needed for a high-definition movie with surround soundcan be handled, with room for future requirements. All this data is kept in the digital domain, as there are no D/A or A/D conversions needed, to ensure the highest sound and video quality available.
THX Select 2: THX Select2 certified receivers deliver optimal quality audio and video presentations to small and medium sized home theaters. A viewing distance of approximately 10 feet / 3 meters from the display to the listening position is best served by these specifications, which translates to a 2,000 cubic foot room. Based on the same values and principles of THX Ultra2, THX Select2 certified receivers deliver exceptional quality to smaller home theater environments. THX Select2 specifications are designed to address the growing needs of the newest generation of home entertainment enthusiasts - those who crave immersive DVD, music, and video game experiences, but do not have the space for a dedicated 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).
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.
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.
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.
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.
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.
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.
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.
7.1 Multichannel Inputs: The emergence of HD-DVD and Blu-ray discs promises to bring unparalleled realism to home theater. Dolby and DTS have each developed improved audio formats to be encoded on these new DVD discs that will superbly complement the latest in highdefinition video. By connecting a player compatible with these new audio codecs to an Onkyo A/V receiver equipped with 7.1 multichannel inputs, you will be able to experience extreme sonic clarity from these new discs, while retaining the full use of the receivers other onboard codecs.
RI (Remote Interactive): With Onkyos exclusive RI (Remote Interactive) system capability, you can integrate and operate all compatible components through a single remote control. Whats more, RI capability enables you to simply connect the iPod® to your receiver through Onkyos RI Dock for the iPod (DS-A1). Your iPod effectively becomes another Onkyo component from which you can relish a fuller sound that just cant be experienced through headphones. RI capability will also give you remote operability of your iPod for hands-off control over your digital music.

Pros: - Total system looks great, more than I could have asked for. I used the auto set-up micophone that comes with the receiver to adjust the speakers, and that worked well - but I did tweak the rear surround speakers slightly to get the sound I wanted. I put in the DVD movie "The Incredibles" as a test for the sound system - blew me away! shook the walls! Scared the kids! The Polk RM6750 speakers look and sound great - I am glad I didn't spend more to get the Polk RB6880 (from Circuit City)at twice the cost! You will not be disapointed with these speakers. I went from using 5 remotes to using just one - the one that came with the receiver. I also have only one HDMI cable from the receiver to my TV. You can also transfer specific remote functions of your choosing from each component remote - you don't have to transfer "all" remote functions if you don't need all of them.Read more ›
The shipment from Amazon was amazingly fast, appearing in just two days. Packaging of the unit by Onkyo was excellent, and installation/ integration into my setup was very straight-forward. I must say that I am accustomed to home theatre installations with lots of wires, read (and follow) instructions, and expect instructions to be confusing. In this case, the manual is very well written, in legible English, a decided plus. The Audyssey system was in no way difficult to use, and the results (speaker distances read by the system) were extremely accurate. One note here is that reviews of the Denon have stated that same Audyssey system measures sound in three separate areas, to maximize the listener's enjoyment even if they are not in the one "sweet spot." The Onkyo system measures just one location. Since I am the one sitting in the single sweet spot, I was not overly forlorn.
The unit automatically detects the incoming digital sound (DTS, Dolby, etc) so I have not had then need to fiddle with them on the fly. There are a host of settings if you indeed feel the need to modify them, but any incremental gain I might attain by fine-tuning those myriad settings just doesn't seem worth the effort.Read more ›
