“Experience Seriously Capable Home Theater with Stunning Versatility To best appreciate the versatility of the TX-SR505, think of the home entertainment components that define today’s consumer electronics landscape. It’s a formidable selection, with HD-ready displays (from the first generation to the latest 1080p models), DVD players (including the latest Blu-ray and HD DVD players), gaming consoles (such as the Xbox and PlayStation 3), set-top boxes (consider PVRs offering HD transmissions) and MP3 players (specifically the dominant iPod).With the TX-SR505′s HDMI transport enabling pass-thru sources up to 1080p and component video supporting 720p and 1080i sources, this A/V receiver is a fine investment for those who want the best of what’s available today…and tomorrow. Also, with the ability to tune the TX-SR505 to your room’s surroundings through Audyssey 2EQ, you’re looking at a seriously capable entertainment control center, without the excessive price tag.

192/24 digital-to-analog 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.

Audyssey 2EQ to Counteract Room Acoustic Problems
Loudspeakers are specifically designed to deliver sound without distortion or coloration. Nevertheless, walls, furniture and other objects reflect and absorb sound, creating distortion that is unique to your own space. To counter this, Audyssey 2EQ corrects problems both in frequency response and in the time domain (where most of the problems lie), across the entire listening area. The results are immediately obvious—a clear, precise and natural sound.

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. There’s 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
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 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.

HDMI is fully backward compatible with PCs,displays and consumer electronics devices incorporating the Digital Visual Interface (DVI) standard. Both HDMI and DVI were pioneered by Silicon Image and are based on TMDS, Silicon Image’s powerful, high-speed, serial link technology. HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel digital audio, and with 5 Gbps of bandwidth, HDMI can accommodate future enhancements and requirements. Because HDMI was designed specifically for consumer electronics applications, it offers an array of additional consumer enhancements. As digital content can manifest itself in a variety of sizes, resolutions and formats, HDMI-enabled systems will automatically configure to display content in the most effective format. In addition, HDMI enables a single remote point and click, allowing manufacturers to deliver home theater systems that automatically configure from a single command from a remote control — turning on or off the components necessary to view a DVD, listen to a CD, or watch cable or satellite TV.

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.

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 receiver’s other onboard codecs.

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.

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 360 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.

RI (Remote Interactive)
With Onkyo’s exclusive RI (Remote Interactive) system capability, you can integrate and operate all compatible components through a single remote control. What’s more, RI capability enables you to simply connect the iPod to your receiver through Onkyo’s RI Dock for the iPod (DS-A1). Your iPod effectively becomes another Onkyo component from which you can relish a fuller sound that just can’t be experienced through headphones. RI capability will also give you remote operability of your iPod for hands-off control over your digital music.
