Onkyo TX-SR608 7.2-Channel Receiver: Your Versatile Home Theater Centerpiece
Experience an entry-level A/V receiver that delivers performance above and beyond its value. The Onkyo TX-SR608 features six of the latest HDMI 1.4 inputs (including one front input) for simple, 3D-ready hookup of all your high-def sources, with true 1080p upscaling video. The Universal Port for Onkyo peripherals lets you enjoy your iPod or iPhone using optional Onkyo docks (sold separately). Its audio processing incorporates quality Burr-Brown DACs, lossless Dolby and DTS codecs, and the expanded surround formats of Audyssey DSX and Dolby Pro Logic IIz. Three-stage inverted Darlington circuitry and jitter-cleaning technology work to ensure extremely precise and faithful amplification.
HDMI® 1.4a Support for 3D Video and Audio Return Channel
The TX-SR608's six HDMI inputs let you simultaneously connect high-def sources such as a Blu-ray player, a gaming console, and a cable/satellite tuner. As the latest version of this connector, HDMI 1.4a adds the exciting possibilities of 3D video and an Audio Return Channel. 3D video is the next big thing in home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible HDTVs on the near horizon--the TX-SR608 gets you ready for this next generation of content at a surprising value.
The Latest Hi-Def Audio Decoders for Rich, Lifeike Movies and Music
In addition to full THX® Select2 Plus™ certification, the Onkyo TX-SR608 A/V receiver can decode Dolby® TrueHD and DTS-HD Master Audio™—two lossless formats that enable delivery of a bit-for-bit soundtrack identical to the studio master track. Previously available only on mid-range and high-end receivers, now you can take full advantage of your Blu-ray movies for a true cinematic audio experience. The TX-SR608 also handles Dolby® Digital Plus and DTS-HD High Resolution Audio™.
Audyssey DSX™ and Dolby® Pro Logic® IIz Add New Dimensions to Surround Sound
The TX-SR608 offers two new surround-sound technologies from Audyssey and Dolby that offer exciting new ways to set up the speakers in your home theater system. Audyssey DSX lets you incorporate "front wide" speakers in place of the usual surround back speakers to expand the width of the soundstage. Set up at a recommended 60° off center, these channels help to produce a more realistic soundstage and a more immersive listening experience.
Alternatively, Audyssey DSX can reconfigure the TX-SR608's surround back channels to deliver "front height" channels. These channels carry ambient, non-directional audio that adds a new vertical dimension to your movies and games. Dolby Pro Logic IIz provides a similar front height speaker option that likewise works to create a more enveloping home theater experience.
A Suite of Audyssey Technologies Crafts Your Ideal Listening Environment
Beginning with the TX-SR508 all 2010 Onkyo A/V receivers come with a suite of Audyssey technologies that help create the most suitable listening environment for your home.
- Audyssey 2EQ™ tailors multi-channel audio for your home theater speaker set-up by measuring three room positions and applying a resolution filter to the satellite speakers to correct for room acoustics.
- Audyssey Dynamic Volume™ automatically compensates for volume fluctuations in different audio content—for example, during commercial breaks—while optimizing the dynamic range.
- Audyssey Dynamic EQ™ maintains a consistent bass response, tonal balance, and surround-sound effect at different volume levels, so you can enjoy the natural dynamics of your content regardless of the volume.
Advanced Faroudja Video Processing with 1080p Upscaling
Faroudja DCDi Cinema (Directional Correlational Deinterlacing) video processing offers several advantages. This processor can accept any video signal, regardless of the source resolution, and upscale it to 1080p to match the native resolution of your high-definition display. What's more, DCDi Cinema effectively removes video artifacts such as jagged edges during the video signal deinterlacing process. Enjoy smooth progressive-scan video images, even during fast-moving sports and action scenes.
Convenient Overlaid Graphical On-Screen Display via HDMI
Changing your A/V receiver's settings is now more seamless than ever, thanks to the TX-SR608's new overlaid graphical On-Screen Display (OSD) feature. Simply press the Home button on the included remote controller, and semi-transparent graphical set-up menus appear overlaid on the video image you're watching. This means you can adjust the settings immediately, without having to switch back and forth from a blank screen background.
Universal Port for Single-Cable Connection of Optional Onkyo Dock for iPhone™/iPod® or HD Radio™ Tuner
A proprietary Universal Port located on the rear side of the Onkyo TX-SR608 lets you connect an optional UP-A1 Dock for iPhone/iPod or UP-HT1 HD Radio Tuner (both sold separately). If you have both peripheral devices, they can easily be "daisy chained" via an input on the UP-HT1. A key advantage of the Universal Port is that it accepts video and audio signals through the same cable that sends a power supply from the receiver to the devices. Net result: more connectivity, less cable clutter.
Wide Range Amplifier Technology (WRAT)--A Total Design for Amplification Power
The cornerstone of any Onkyo A/V receiver, WRAT supports high-quality audio reproduction of the latest high-definition A/V formats. It comprises three key elements: A low negative feedback design for cleaner audio across the frequency range; a closed ground-loop circuit to cancel individual circuit noise and keep the ground potential free of distortion; and a high instantaneous current capability to handle speaker reflex energy and impedance fluctuations.
- Onkyo's low negative-feedback design with audiophile-grade, close-tolerance components achieves a frequency response out to 100 kHz for high-definition and regular DVD formats, high-resolution DVD-Audio and Super Audio CD, regular CDs, digital music files and the latest gaming software.
- A sophisticated closed-circuit design enables each circuit to go and return directly to the power supply which, coupled with the use of thick brass grounding plates, helps cancel any individual circuit noise and keeps the ground potential free of distortion.
- The instantaneous current capability of Onkyo's WRAT receivers exceeds that of most conventional units, which commonly have less than half the current capability. An Onkyo receiver will deliver movie soundtracks with cinema-standard dynamics and clarity.
Additional Audio Features for the Most Versatile Home Theater Applications
Playback of Different Audio Sources in Two Different Zones
With Powered Zone 2, you can enjoy surround sound entertainment in the main room, while playing back a different stereo source in a second zone equipped with a pair of speakers. Alternatively, you can use the Zone 2 line out to send an unamplified audio signal to an amplifier (and speakers) in the second room.
Four Game Modes for More Realistic Action
These four gaming modes create an audio experience with more realism and impact. You can select from Rock, Sports, Action, or RPG (Role Playing Game) modes to match your gaming content.
Music Optimizer to Support Compressed Digital Music Files
While MP3 or AAC files may sound fine on a portable digital player, the limitations of these compressed files can be exposed when played back through a home entertainment system. Onkyo has designed onboard Music Optimizer technology to improve the quality of compressed audio signals. Compressed music loses a substantial amount of bit information at higher frequencies, so the Music Optimizer technology works to overcome this limitation and enhance audio quality.
HD Radio™ and SIRIUS™ Satellite Radio Ready
Onkyo's TX-SR608 offers compatibility with optional tuners for both HD Radio and SIRIUS Satellite Radio. HD Radio broadcasts your favorite AM and FM stations digitally, with none of the hiss, distortion, or station drop-off of analog radio. SIRIUS provides exclusive access to over 130 channels of commercial-free music, sports, news, talk, and comedy.
Theater-Dimensional Circuitry Easily Puts Surround Sound Anywhere
Onkyo's exclusive Theater-Dimensional circuitry takes the complexity out of conventional surround-sound set-ups 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.
Remote Interactive over HDMI (RIHD)
Onkyo A/V receivers offer integrated system control with certain HDMI-compatible high-definition displays, DVD and hard-disk recorders, and Blu-ray Disc players. With one remote control, you can control functions such as Standby, Volume, and Direct Change.
Front-Panel Audio Input for Portable Devices
If you have an iPod® or other MP3 player, you can connect it to the TX-SR608's front panel for quick and convenient audio playback. Your player's compressed digital music files can then receive a quality boost from the receiver's Music Optimizer technology.
Top Customer Reviews
With that caveat, the Onkyo is a terrific performer offering strong power (power consumption is up from the 607 to a very grown up 756 watts), terrific flexibility (four speaker terminals can be assigned to wide, height or zone 2). The Denon is limited to merely 7 speaker terminals and the Pioneer has only a pair of assignable terminals. The Audyssey auto-callibration (2EQ) is a notch behind Denon, but the inclusion of Audyssey DSX (for wide arrangements) is a feature that the Denon does not offer. While it lacks the USB terminal for Ipod playback of the Pioneer and the Denon, it does offer a computer input which might resolve the HDMI handshake nightmare many face with htpcs.
Onkyo rather smartly included a fan atop of the receiver, which is silent and all but eliminates the historical Onkyo toaster oven effect.
I really enjoy this receiver, but found the HDMI video molestation issues to quite problematic and what mar an otherwise incredible buy. Hopefully Onkyo can issue a firmware update.
Anyway, I absolutely love my new Onkyo 608. I never review stuff, but I wanted to give props to this receiver. I was debating between this one and the new Pioneer 1020. However, I've heard that the amps in the Pioneers don't compare to the amps in the Onkyos. Though I cannot verify the truth of this, I do believe that the amp in the Onkyo is of a very high quality. I have already noticed a tremendous amount of power increase over my previous Yamaha receiver (the model that was included with the Yamaha 390 HTIB). This puts out a lot more sound, and I absolutely love the ability to take advantage of HD audio. I noticed a huge fidelity difference in the compressed Dolby Digital track for Dark Knight and the Dolby True HD. The track was intended to include a lot of bass, and the HD includes all of it. The regular Dolby did not compare. Thus, HD audio is definitely worth having if you own a blu-ray player. Just like video quality (some transfers are better than others; aka reference quality), not all sound tracks will have a huge difference, but to me, it's still worth it. Back to the Onkyo: I love it. There are so many settings that you can tweak. If you like the ability to configure your equipment, you will love this receiver! You can also bi-amp with this receiver, which is nice if you don't have 7 speakers.
I really love Audyssey DSX it really gives a much fuller sound to the movie soundtrack. I use the front wide setup as opposed to the front height channels.
The Audessey EQ feature will automaticly detect how many & what size your speakers are. It also sets up the crossover frequency. You can go back in and do it manually. There are also many other settings you can play around with, such as THX mode (if you have THX speakers) Dolby true HD & DTS-HD master audio,
Dynamic volume control,A/V sync , Intellivolume and others. You can reasign and rename the inputs. It is HD radio ready, SIRIUS sattlelite ready and THX select 2 certified.
Our family really enjoys the better sound. I currently have Kenwood HTIB speakers hooked up. The Onkyo makes them sound better.
I have replace the center channel speaker with a Definitive Tech ProCinema 1000. What a Difference! I hope to replace all the speakers with the Def Tech 1000 line. I'm sure it will sound great with the Onkyo TX-SR608.
I noticed a glitch in the HDMI THROUGH feature. When I activated the HDMI THROUGH feature, which is supposed to allow HDMI signal to pass through with the receiver on standby,it kicks off the 4:3 overide off on my Cable box.Read more ›
