Meet the first of Onkyo’s new A/V receivers built to embrace high-definition media such as Blu-ray Disc and HD DVD.The TX-SR605 7.1-channel A/V receiver embodies this new generation, with its remarkable processing capabilities courtesy of HDMI (High Definition Multimedia Interface).With the ability to keep everything in the digital domain, the TX-SR605 provides complete control of every video and audio format available today. Bringing high-definition A/V processing to Onkyo’s renowned approach to sound gives this A/V receiver a distinct advantage in the home. Delivering the latest in usability and versatility—such as multi-room playback, a full connectivity suite (with switching and upconversion), room calibration and integrated system control—the TX-SR605 is poised to set new benchmarks in performance-driven home theatre.

HDMI™ (High-Definition Multimedia Interface)
|
|
|
The latest in digital interface technology is here and it goes by the name of HDMI (High-Definition Multimedia Interface). This high-bandwidth interface supports not only remarkable amounts of uncompressed digital video but audio as well. Up to 5 Gbps of data, more than twice what’s needed for a high-definition movie with surround sound, can 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. Unparalleled amounts of compressed or uncompressed digital audio and video—up to 5 Gbps of data—can be handled with just one high-speed cable.

Benefit 1: Uncommonly Low Negative-Feedback Design—so you’ll enjoy cleaner sound on programme peaks
|
Although NFB (negative feedback) is the most cost-effective way to reduce noise at lower frequencies, there’s a sonic price to pay: larger amounts of NFB severely inhibit an amplifier’s transient response—the ability to respond to large signal gains (e.g. explosions and musical finales)—and actually distort sound at high frequencies. That’s why our engineers use a low negative-feedback design, with audiophile-grade, close-tolerance components at critical points in the signal path, to achieve a frequency response out to 100 kHz. That means you can fully enjoy the sonic benefits from such high-resolution formats as DVD-Audio and Super Audio CD as well as your regular CDs and DVDs.
|
|
Benefit 2: Closed Ground-Loop Circuits—so you’ll enjoy greater maximum volume without distortion
|
If an amplifier’s ground potential (voltage) fluctuates during playback of movie soundtracks or musical performances, you wind up with unpleasant noise. In an open-loop circuit design, all circuits are connected to the power supply via one loop. If all circuits share the same loop (like on many amplifiers), the noise multiplies exponentially. Onkyo’s sophisticated closed-circuit design allows each circuit to go and return directly to the power supply. This cancels any individual circuit noise, and keeps the ground potential free of distortion.
|
|
Benefit 3: High Instantaneous-Current Capability—so you’ll enjoy film soundtracks with greater impact
|
Audio signals are very complex. After the amplifier outputs such signals to a speaker, the speaker itself accumulates energy. When the speaker reflexes, it sends energy back to the amplifier. The amplifier must immediately be able to supply a large amount of high current to cancel the speaker’s reflex energy, and instantaneously send out the next signal. The same high current is also necessary to handle speaker impedance fluctuations, which on occasion force an amplifier to provide four to six times its usual current load. The instantaneous current capability of even Onkyo’s least expensive WRAT receivers is far better than that of most conventional units. This is because competing designs commonly have less than half the current capability. The result? The high-current capability incorporated into all Onkyo receivers means your receiver can deliver movie soundtracks with theatre-like dynamics and clarity—so you’ll get the same exciting sonic slam that you experienced in the cinema.

7.1-Channel Input
|
|
|
|
With the upcoming release of HD-DVD and Blu-ray Disc, Dolby Digital and DTS have prepared audio formats that represent the future of digital audio entertainment. By connecting an HD-DVD or Blu-ray Disc player with the respective high-definition audio codecs to the receiver via its 7.1-multichannel inputs, you will be able to enjoy superior audio quality.

CinemaFILTER™
|
|
|
|
The tonal balance of a film soundtrack can be edgy and bright when played back over audio equipment in your home - this 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.

Multizone Playback through Powered Zone 2
|
|
|
|
Powered Zone 2 brings multi-zone entertainment to your home. With Powered Zone 2, 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 amplifier in Zone 2, or using only a pair of speakers in Zone 2. In the former case, you can enjoy 7.1 surround sound in the main room and play a different A/V source in Zone 2. In the latter case, you can have 5.1 surround sound in the main room and play a different (stereo) AV source in Zone 2.

Theater Dimensional
|
|
You can experience the excitement of surround sound from as few as two ordinary speakers.
|
Onkyo's exclusive Theater-Dimensional circuitry takes the complexity out of conventional surround-sound setups 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.

Video Upconversion for HDTV Connectivity
|
|
|
|
As the most advanced interface for transporting both uncompressed highdefinition (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. 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 upconvert any other source connected by component, S-Video or composite connections. 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 upconversion) to get the best video images available.

Audyssey 2EQ
|
|
|
Even though loudspeakers are designed to deliver sound without distortion or coloration, the acoustic problems presented by a room’s profile will determine the overall sound presentation. Walls, furniture and other objects reflect and absorb sound creating distortion that is unique to your own space. To counter this, Audyssey 2EQ detects speaker polarity & distance, and then sets levels, delays, and crossovers and measures room acoustics at two listening positions. In this way, a wider listening area is covered than by simply measuring at one position as with many systems. Some systems try to correct for multiple positions and then average the results out for a solution. However, this simply smooths out the frequency response peaks and dips. Audyssey 2EQ corrects problems in both frequency response and time domain (where most of the problems lie) in the entire listening area. The results are immediately obvious—a clear, precise and natural sound.

DTS-HD® Master Audio Codec for Next-Generation Audio
|
|
|
|
The leading audio codecs for the new multichannel formats for Blu-ray Disc and HD DVD are Dolby TrueHD and DTS-HD Master Audio. Both technologies enable a lossless, bit-forbit reproduction that is identical to that of the studio master. In other words, the same audio quality as in the studio engineer’s final mix. All high-resolution channels can be received from compatible Blu-ray Disc, PlayStation® 3, HD DVD and Xbox™ 360 components.
