Onkyo's TX-SR706 packs a high-current amp, sophisticated processing, and plenty of audiophile and videophile extras into its sturdy frame. It's also earned Lucasfilm Ltd's THX Select2 Plus certification for home theater excellence — you'll enjoy thrilling, high-impact surround sound for all of your movies, music, TV shows, and video games. Exclusive THX Plus listening modes keep surround effects detailed and accurate, especially at lower volume levels. The 'SR706 also features decoding for the latest surround sound formats, including Dolby® TrueHD and DTS-HD™ Master Audio — two high-resolution surround sound formats found on many newer Blu-ray players and discs.

Flexible video connections and 1080p HDMI upconversion
This receiver's 1080p-compatible HDMI inputs let you connect up to four digital high-def sources for easy switching. And thanks to analog-to-HDMI conversion, you can pass all of the video sources in your system to your TV via a single HDMI cable. Plus, the 'SR706 can upconvert any non-HD source to a digital video signal with up to 1080p resolution, letting you enjoy maximum picture quality on your HDTV with standard-definition DVDs and older video sources.

Precision auto setup tailors sound to your room
The 'SR706 includes Audyssey MultEQ®, a sophisticated speaker calibration system that helps you get the most accurate home theater sound possible. This receiver uses the included microphone to analyze sound from up to six different listening positions, then automatically adjusts level, equalization, and delay settings for each of your speakers. You get precise response across a wide listening area instead of just a single "sweet spot," so everyone in the room can enjoy optimal home theater sound.

Multi-room music and more
Two-room/two-source audio capability lets you enjoy surround sound in your main room while a housemate listens to a different stereo music source in another room. A handy learning/multibrand remote makes it easy to control all of the components in your system. You can integrate your iPod® by adding Onkyo's handy control dock. This receiver is also XM Ready and compatible with XM's HD surround music channels. Or connect an optional SiriusConnect™ home tuner kit to enjoy SIRIUS satellite programming.

Exceeded Expectations

Written By Dave, Rockford, Illinois on Saturday, April 18, 2009

Crutchfield Customer Review (What's this?)

I purchased the Onkyo 706 after much thought and deliberation. There were so many receivers to choose from and I actually intended to purchase a different brand. However, Brian at Crutchfield patiently and expertly explained the pros and cons of each brand and model and how the Onkyo brand is very effective at recreating the theater like sound and ambiance at affordable pricing. With his help I was able to make an informed decision in selecting the 706. The four HDMI inputs were also a plus.

The sound this unit puts out is outstanding. I don't have surround speakers, so I can't take advantage of THX processing but the "theater dimensional" sound field will rattle your windows and strain your eardrums while watching a movie. The sound is also warm and detailed and I didn't realize what I was missing. I have the volume set to absolute and while it goes up to 99 I listen at 26 to 35 depending on the movie and it still gets very loud while maintaining pristine sound quality.

No buyer's remorse with this beast of an a/v receiver. The manual isn't perfect (no manual is) but I feel it's much better than some people give it credit for. Crutchfield technical advisers lived up to their reputation as knowledgeable and courteous.

Crutchfield Customer Review (What's this?)

My first A/V receiver - goes with my first ever surround sound set-up (7.1 in ceiling w/ sub) so now when we watch a movie on dvd - WOW! I have it paired with a Denon 1940 dvd player which really makes for a great picture (better than Yamaha S18000 as well as great cd sound. I've even purchased a couple of SACD's and again - WOW! It was also really nice using the Audissey speaker set up feature - the easy on screen guide let me know that I had a couple of speakers wired incorrectly - after switching them - el perfecto!

I also like all the available sound modes and the ability to preset what I want for different incoming signals. (stereo,dolby digital, dts, etc.) I can only imagine how good blu-ray will sound! The switching is a little slow but overall I think the amp is of great value which is important to me.

Last thing - the Onkyo's manual and quick set up guide really makes things easy to get up and running.

Better Than Expected!

Crutchfield Customer Review (What's this?)

I have owned the TX-SR706 for a couple of weeks now and it is much more than expected! I chose this model simply because it does more than the compitition for the same price. I have upgraded from a Sony STR-DB940 for the HDMI. I am really impressed with the manual settings that are available for adjustment. The microphone got everything pretty close, however I was required to make a few minor adjustments. I personally can not see any difference in the video upconversion, however other people can, so that is a nice feature for them. I love the late night feature for when the kids are sleeping.
I do not like the fact that the rear or surround sound level is not easily adjusted while watching a video source. Othere than that minor complaint, it is the best receiver I have owned so far.

Onkyo TX-SR706

Crutchfield Customer Review (What's this?)

I am extremely happy with this receiver. I purchased this to replace a very old (more than 5 years) receiver. I recently upgraded to an HD DVR DirecTV receiver and a 52 inch LCD. I wanted to use the HDMI connectors. I can't believe the difference in the picture quality. Now I am able to connect my satellite, Blue-Ray and LCD together to have a great picture.

I'm amazed by the sound that I get through this receiver. My old receiver must not have been able to take advantage of the speakers and subwoofer I had connected to it. The sound now is so much better. I have actually been watching some of my older movies just to hear and see the better quality.

I had been hesitant to upgrade because there seemed to always be a newer option. I'm sure there are better options even today, but for my needs I think this is perfect. When I do upgrade I will definitely come to Crutchfield first. My entire experience has been great.

Aweswome Value

Written By Michael, Ocala, Fl on Monday, March 16, 2009

Crutchfield Customer Review (What's this?)

I have owned Integra components previously and swear by their quality build and superb musical reproduction. However, I replayed a Denon 7.1 receiver which was working perfectly with this Onkyo solely because of the HDMI connections and Audessey speaker room set up. What tipped the scale was Onkyo's reputation for quality even though I was a bit concerned that the receiver was built in Malaysia--previous Onkyos always were built in Japan, but that concern was proved baseless. This is a beautifuly constructed unit and has a very smooth feel to all the controls.

One minor complaint is the relatively slow switching between inputs; it takes some time getting used to--perhaps it's the fault of the HDMI connection--I don't know.

I have owned it and enjoyed it for several months and to close this review I am going to say that I believe the sound reproduction to be slightly inferior to my older Denon without HDMI, especially in the bass. But don't worry, the unit produces very adequate bass especially on action movies on Blu
-ray played through DTS Master and Dolby True HD.

Highly recommended.

Very Nice

I am not usualy one to rate things over the internet. But I had to With this Onkyo. I upgraded my Kenwood VR-707 Reciever to this Onkyo 706, Not only was the autosetup fantastic and the OSD, but the sound just blows me away. I currently have a 6.1 Setup with a bluray player and lcd screen. I really love what this reciever has to offer many more options and with my viera link if I shut my TV off everything goes of if I turn my blu ray on everything comes on. Crutchfield also helped me with a small problem I encountered but I got right over it. So I rate this 5 out of 5 and am now an onkyo fan. I also recomend this reciever to anyone wanting a mid level reciever Thanks Crutchfield.

Crutchfield Customer Review (What's this?)

Unbelievably easy to set up with all the easy to read and follow instructions. I married the receiver with a Sony 350 blue-ray player, Monster power HTS 800, Dish Turbo-HD, an Epson 1080UB projector, and a DaLite screen that comes with JBL speakers built into the frame of the screen. The 7.1 surround and the auto setup on the Onkyo worked wonderfully. I had one question, called Crutchfield and in less than five minutes had the answer, thanks. There is no place in the room where it doesn't sound great. It took all winter long to get the room done by myself but was well worth the wait and is ready for March Madness just in time.

The remote works great and it's easy to switch from input to input. We look forward to many years of excellent listening.

Crutchfield Customer Review (What's this?)

Very nice receiver with TONS of features. I can't believe how many listening options there are. The automatic speaker setup using the supplied microphone was simple and worked flawlessly. On screen display makes it very easy to make changes. 7.1 sound is amazing. Watched Transformers on BluRay and it sounded like the house was coming down in some of the battle scenes.

I upgraded from an older model Denon that didn't have HDMI inputs. Denon is still a great unit and will move upstairs, but the Onkyo will run the Plasma and BlueRay set up downstairs.

For the price, you can't beat it. Don't hestitate, just buy it. Most comparible models on power are $800 or more and don't have the THX certification.

Written By Dale, Duluth, MN on Monday, March 02, 2009

Crutchfield Customer Review (What's this?)

We've been using Onkyo equipment for 14 years and wanted to keep a point of familiarity with our new HDMI AV equipment. Our experience with Onkyo has been great - no defects, problems or failures, PERIOD! This stuff is rock solid. So, why are we buying a new receiver? - Because we need HDMI compatibility. The old system still works perfectly. The new receiver was bought with a 5.1 speaker system and was recommended by one of Crutchfield's sales consultants. I was really pleased that they were able to recommend a completely satisfying sytem within budget constraints. The new receiver arrived quickly and in good condition. It was well doumented and well illustrated. First-time system check was flawless. I haven't made it through advanced setup features yet but can say that I'm very pleased with the new equipment. We'll be adding an HDTV with a Blu-ray DVD player in the very near future - that's when I plan to go through advanced setup and get everything tweaked. Right now, it's connected to our old CRT TV and Sony DVD - it performs as you would expect with this type of equipment.

Crutchfield Customer Review (What's this?)

I am very happy with my new Onkyo TX-SR706 receiver. I have other Onkyo receivers currently and they are still going strong. I needed the 1080p pass through and HDMI connectivity that this receiver has. I really love the sound quality that this receiver has! It fill my entire listening room and you cant tell where the sound is coming from. It is truly top shelf surround sound! Set-up is a lot easier with the set-up mic. It does run hot so plan ahead with good space between your components. Onkyo has a terrific deal with this receiver. Crutchfield support before and after the sale is legendary as always!

I have owned many different sound systems over the years. 30 years In fact, by far and away this receiver packs more features and power for the dollar than any one I every owned. I recommend this product over any other in it's price range and even much higher. I had checked out Denon, Sony, Panasonic and none come close to the performance you get out of this product.

Good but better choices are out there

Written By DD, Fruita, CO on Wednesday, February 25, 2009

Crutchfield Customer Review (What's this?)

One of the easiest to setup, especially with it's great onscreen setup menu! Unfortunately the sound was just average. Sound was OK but for the price it should be much better. No "B" speaker option and multi-room only available if you abort the back surrounds. The remote was good but to change surround modes you have to toggle through each field to find the one your after. I think the the original pioneers in HiFi are still the best choice - Marantz.

Awesome easy setup out of the box

Written By Jeffrey, Lincoln Park, NJ on Tuesday, February 17, 2009

Chose this receiver for a 7.1 system. I just installed it (haven't yet really got into the menus for finer tuning) and it works very easy right out of the box. As in other reviews, it does get very hot so be sure to put it somewhere with vents. During set up it has speaker tones so you can be sure you don't get your left/ right speakers mixed up (I did so it was an easy fix). I didn't even have to read the directions to get the basic setup working. A great receiver that has plenty of potential.

Features and ease of use!

Written By Martin, Albertville, MN on Monday, February 16, 2009

Crutchfield Customer Review (What's this?)

First off I just wanted to say I ordered this on backorder and it ended up coming about 10 days earlier than originally anticipated so that was nice. Setting it up was straightforward, this is my first receiver with hdmi connections, and boy is it nice. Speaker set up was a breeze, no problems at all for my microphone. The system is pretty intuitive and easy to adjust. Of all the things I like about the receiver I think the remote is my favorite, being able to put all the other remotes away is really nice.

The only problems I had were some issues with compatibility on an older model cable receiver, and the record button for my dvr didn't program into the remote for some reason. The cable receiver issues didn't end up being a problem after I got a newer model receiver, the Crutchfield help line was very helpful in solving this, they even contacted Onkyo for me.

Crutchfield Customer Review (What's this?)

This receiver is AWESOME...Most impressive was the way and ability to balance the speakers in the room. I have Infinity towers in the front; another brand in the back and center; and a "weak" 12" sub in my familyroom. This receiver automatically balanced the speakers in perfect harmony. It has EVERYTHING you need in a speaker, including 4 HDMI inputs. With the ability to give sound to a DVD in my familyroom AND AT THE SAME TIME play FM or CD music out on my back deck is exactly what I needed. I'd buy it again in a heartbeat.

No Brainer Setup, Great Features

Written By Nick, Park City, UT on Thursday, February 05, 2009

Great product ... easy to setup and great sound. The Audessy setup was pretty idiot proof ... move the provided mike around the room to where you sit and it figures all the sound setting out.

We do use a Logitech Harmony 880 remote (would highly recommend if you've got multiple components) ... the Onkyo integrated easily with that making controlling all the components a snap.

The only annoyance (minor put why I gave it 4 stars) I see is with the video processing. It does a great job of upscaling the video to 720p from lower resolutions on component connections (our cablebox uses a component vice HDMI connection). But, after a few minutes of being turned on the TV screen will go black for a couple of seconds. I think the video processor spends the first couple of minutes analysing the video signal and then adjusts it during the blank period.

It also it doesn't apprear to do any upscaling for HDMI connections. But, this could just be because my blueray player already does some upscaling so the Onkyo just passes it through.

Replaced a 6 yr old Onkyo to gain HDMI switchability. The old receiver was good but this one is great. Love the on-screen menu for setup, etc. Also, found that the back of the receiver was much more organized for easier wiring setup than the old one. The receiver still has capabilities to explore. I'm using the setup as 5.1 surround in main room and 2 powered channels in a second room. The 2nd zone was easy to setup and operate. Overall, great value!

Bought this Onkyo to replace a 10 year old Kenwood 5.1. I now have a 7.1 speaker system with a blu-ray player and a 40" Sony LCD 1080p. This unit has great sound and many features for the price. The setup was easy and the auto calibration for the sound worked perfectly. My small living room sounds better than any theater. I also use zone 2 for speakers outside on my deck that I send music to from itunes on my computer. As with any new unit, read the directions and spend time tweaking all of the settings to get the most out of it. You will not be disappointed. Blu-ray movies sent through HDMI cables and this receiver look and sound amazing. Jackie at Crutchfield was great in helping me choose between 3 different receivers for the one that was best for my situation. The unit arrived quickly and was well packaged. I would buy from Crutchfield again for any of my electronic needs. Enjoy the Onkyo.

Onkyo lives up to its reputation with the TX-SR706. It's one of the most soidly constructed receivers I have owned and its sound is nothing short of exceptional. I use headphones exclusively for my listening and have coupled the Onkyo with Sennheiser HD-600 fitted with an Equinox cable. The result is full bodied sound that does not grow tired on the ears. The TX-SR706 has more than enough power and though I was happy with the Marantz receiver I had previously, I am thrilled with my choice to go with Onkyo and thanks to Crutchfield for their suggestion.

Purchased Onkyo TX-SR706 to replace older Sony. Unit is connected to Bose front and rear system. Was amazed at the quality and fullness of the sound delivered by this unit. Have added Sony Blue-Ray BDP-S550 since I purchased the receiver, the sound and picture are amazing. I will probably never go a theater to see a movie again.

Best for the money

Written By Kyle, Colorado Springs, CO on Thursday, January 22, 2009

Crutchfield Customer Review (What's this?)

I purchased the 706 to replace another Onkyo, the 603 (no HDMI). I was a fan of the first one, and with this purchase I can now say that I'm an Onkyo devotee. No one else offers the quality and features for the price. Four HDMI ports with up-conversion - enough for the components I've got now plus room to expand. The THX Select 2 enhances sound quality when I'm not listening at reference level, which is nearly always in a house with children sleeping. The Audyssey setup is amazing. I'm still looking over my front door when someone knocks on the TV. Even their instruction manual is good. Stop looking, this is the one.

I've had this for over a month and so far it has been great. The upconversion is excellent and the picture quality and sound is amazing. The only problem I had with it was when I first got it, the automatic calibration of the Audyssey didn't work. I waited and tried it again and it worked perfectly fine the 2nd time around and haven't had any other problems with it at all. It is a great receiver for the money and I would get it again today.

Top Quality and Easy to Use

Written By Anonymous, Philadelphia, PA on Saturday, January 17, 2009

Crutchfield Customer Review (What's this?)

I'll start by saying this is my replacement after first ordering the Denon AVR-1909 and Crutchfield made is easy and painless. This reciever blows away the Denon on many levels but most importantly ease of set up. I won't bash the Denon here but feel free to check out my review of it. I had the Onkyo working in under 1 hour including making connections. It just works out of the box which in this day and age is necessary. To touch on a few, the menus were simple and intuitive, assigning components was a breeze and running audyssey to set speaker levels made it complete. Using HDMI out to your TV is the best way to go to take advantage of all the OSD functions including visual volume level (which the Denon lacked.) Even the remote is great and can replace all your others which again simplifies life. Build quality is strong and sound quality is very acceptable. The Denon may have a slight edge there but I'm willing to sacrifice a tad. My previous receiver was an NAD so I was used to good sound quality but I'm not dissappointed in the least. My main concern was good quality and simple setup so anyone in my house could use the system without calling me to get things working. A great receiver for a good price!

Easy install, great sound

Written By Jeremy, Olathe, KS on Thursday, January 15, 2009

Crutchfield Customer Review (What's this?)

I replaced a Pioneer VSX-815-K receiver with this one. Wow, what a difference. For one, the banana
plugs were much easier to insert and remove from the speaker outputs. The OSD (which the Pioneer did not have) was very well done and easy to navigate. The OSD is also very quick to respond. The only reason I would say it is not is due to the HDMI autodetection but this is very easy to get used to.

About the setup: The setup was so simple that I was done in 20 minutes. Just plug in the mic and let the speaker detection run. Once the calculations are
complete you need to tweak it very little.

The sound quality is a huge upgrade from the other receiver (which is over 5 years old).

All in all, I am very impressed and very happy that I
bought this receiver.

Bang for the Buck

Written By Clyde, Acworth, GA on Wednesday, December 31, 2008

I recently purchased the Onkyo TX-SR706 because of the new sound formats now available with blueray discs. There is a "Bang for my Buck"
advantage for the SR706 when comparring specs/features with simillar brands. I am running a cable box DVR, Toshiba HD-A30 Hi Def DVD player,
DVD Recorder, and PS3 using all 4 HDMI inputs going out to my 50"TV with beautiful video results. The Onkyo, replaced a 6 year old JVC rated at 130Wattsx7 @ 6ohms (which served me well). There is marked improvement in Bass management. I have a 7.1 (8" inwall) set up with a 12" sub, and the deep notes are much more precise, and impactful than I thought possible (ref - Master and Commander Cannon Blasts) because they blend better with the Midbase in my front stage (thanks to flexible x-over options) I screened several 7.1 Master HD soundtracks (War, The Bank Job,) and the discrete sound to the rear, and the full bass during Dramatic transitions was impressive. I was equally impressed with 5.1 soundtracks while using the THX Select 2 surround setting (The Mission Impossible III Bridge scene was incredible,) This setting essentially converts the 5.1 signal into 7.1 playback. I am still tweekin, but I can strongly recommend the Onkyo on the stength of its Bang for your Buck Features, and incredible sound quality for music, but certainly movies. Looking forward to experiencing the Dark knight and Indian Jones with the Family this weekend!

I replaced an older Onkyo receiver with this new one. I am delighted with the ease of set up, the contouring of sound for two speakers in my living
room with the microphone. Using all HDMI connections eliminated the snake pit of RCA cable wires. The rugged construction shows over a Sony I was considering. Thanks to Crutchfield's Sales guidance, and the wonderful after sales tech support, I had it up and running in no time. I sat back watched a DVD and was amazed at the sound quality from this unit. Even at low volume, it's not tinny, but full range. I am both an Onkyo and

Crutchfield Customer Review (What's this?)

With the help of my online advisor Keith, I made the decision to purchase this receiver. It only took 2 days for it to arrive at my location. I couldn't believe how great the system sounds. I have it hooked up as a 5.1 with Zone 2 in a different room. Setup was a breeze and I couldn't be happier.

Excelent Reciever

Written By Robert, Owensboro,KY on Tuesday, November 25, 2008

This reciever is awesome. Very easy to hook up did have a problem with the mic set-up but crutchfield sent me a brand new mic and it work perfectly. The system set up everything perfectly and the THX mode makes it sound exactly like the movie theater. It is very powerful and very easy to hook up, would recommend this reciever to anyone especially since I traded this in for a Sony which this Onkyo blows out of the water. Thanks Crutchfield for wonderful support and I would always recommend them to everyone.

Excellent, High-End Value

Crutchfield Customer Review (What's this?)

When I was an electronics technician I admired the Onkyo brand because of their intuitive and functional design. When I managed service technicians, Onkyo was a brand I trusted for reliability and customer ease-of-use. Those experiences and the cost of the unit made it a natural choice when I started setting up my own small home theater.

This specific model has all the features I need now, and more if I decide to further upgrade my system. It was easy to set up and it functions perfectly for my needs. It has ample power and the quality is impeccable. The buttons are simple and robust, the display has optimal resolution, and the design is attractive. Setting it up was easy, and although I didn't use the automatic set up feature for the speakers it seemed simple enough in the manual. The remote was easy to program and performs most of the functions I need.

The only negative is that Onkyo customer support is weak. They were difficult to reach and unable to provide me an infrared hex code. When I did reach them they were very friendly and wanted to help, they just couldn't provide the code for some reason nor could they tell me why. It may have been a proprietary issue, as these codes indicate the programming logic of the unit. I've since resorted to using the Onkyo remote instead of my old remote.

Bottom line: If this unit matches your functional and power needs, I highly recommend it to A/V novices and installers.

Awesome sound system

This receiver replaces an older system that I have had for a few years. I upgraded because of my new flat panel LCD HDTV. The old system couldn't support it or 1080P.

All I can say is WOW. The sound, versatility and ease of use are second to none. The speakers I already had including the sub woofer worked flawlessly with this new unit.

The only problem I had was with the auto speaker setup. I didn't want to work properly. But setting up the speakers manually was easy to do and much easier then my previous unit.

I recommend this unit highly and that is coming from someone that has been listening to music on stereo systems for 40 years.

You won't be disappointed!

I purchased this new Onkyo receiver to manage a new big screen, blu-ray, surround sound and turntable. I was very pleased with the straight forward on screen set up. The automatic speaker set up made it a lot easier also. Works like a charm. Looks and feels like professional grade equipment, but costs much less. Would I recommend this receiver? Absolutely!

Onkyo TX-SR706

Crutchfield Customer Review (What's this?)

I purchased this product because every Onkyo product I have purchased, in the past still works (11 years later)! This product is a true delight to have in my living room. I used to have a Sony 5.1 DD reciever that worked okay (I thought). I have a inexpensive set of surrond speakers and a HD setup with flat screen and Dish network. After setting up this receiver and turning it on; WOW. My inexpensive speakers sound great, all sound is filtered though the receiver at a digtal level and it sounds great! This stereo has so many options it is hard to determine which one is better. I love how it simplifies the use of all my electronics with 1 remote, and 1 cable to my TV. After doing a lot of research, I bought this once Crutchfield gave it a remarkable price and I am completely satisfied!

If you are looking at this product, know that Onkyo doesn't put out a bad product. Also go to you local electronics stores (Bose, or high end stores) and look at what type of receiver is set up for there demo's on there blueray surrond sound stereo. If the pros use this product to sell there speakers, don't you think you should use this product to listen to your speakers.

Not A Yamaha... But, Very Good

Crutchfield Customer Review (What's this?)

Always owned Yamaha AV Recievers from the RXV-1 on down. (have 3 Yamahas systems in house, now.) Took a chance on this Onkyo.. Set up was a little ticky as I had 14 peiices of A/V equipmemt to hook up.. So had some duplicate inputs to deal with. DSP sound fields are very sparce . But it has "all channel stereo" which is an absolute for me. I like the ease of operation of the Zone 2 as I have three sets of outside speakers and also the 3 - 1.3a HDMI inputs.
Sound quality is good and natural and it seems to have adequate power for my 12 Klispsch speaker system including three subs. That was a hook up challenge. The sales associate at Crutchfield just bought the same unit. I am satisfied..as it is a good bargin..

A pleasant surprise

Need a new receiver to work with my new blue-ray player. Been using Yamaha for a long time, but mine does not have HDMI on it. A friend of mine has an Onkyo TX SR705 and I love the quality of the audio. When I see this SR706 receiver also has Faroudja DCDi chip to do HD upconversion and the price is reasonable, I order it right away.

Hookup is easy, I am particularly impressed with the Audyssey auto setup. It saved me lots of time and effort to define the speaker location and audio level. It works well with my Bose speakers and almost like gives them new life! This receiver performs well in normal volume and the most impressive thing is it also sounds great in low volume setting. I can enjoy a late night movie without waking up the whole neighborhood. DVD looks way much better via the 1080p upconvestion.

I am extremely happy with the receiver, if you are looking for a receiver to work with your new HD TV, Blue Ray player or a game console, increase your budget a little bit and the sound and video quality improvement is well worth the extra money.

Crutchfield Customer Review (What's this?)

Interestingly enough as in another review I too used this receiver to replace another damaged by a lightening strike. This time I have protected it with a more suitable surge protector.Having had a number of high end receivers in the past including Yamaha, Pioneer and so on I find the quality and clarity of output superior to most. Having been in audio sales in the past one watchword of ONKYO is its ability to make the most of any quality level speaker attached to it. The broad array of up to date input, output, and speaker options make this unit a fine selection for the long term, thus making the investment justified. Other buyers need not be deterred by its higher end multiple possible speaker configurations since I have incorporated it into a smaller home office / personal den venue. If in the future I move my seven (7) component five (5)speaker system to a larger area I feel confident that I and my system will be ready.

If I have any criticism it is that the installation instructions and options for some components are displayed in a too complex/ overlapping manner. It would be better if each option would be laid out separately even if it would make the installation manual much thicker.

Finally I would rate this unit as a Top Buy and a real value, yes, a true bargain at this price.

Onkyo TX-SR706

Written By Richard, Central Texas on Tuesday, August 26, 2008

I have always been devoted to the pre-amp, amplifier, and separate components concept using manual equalization, and digital time delay, until recently when our house was struck by lightning. I used this unfortunate incident as an opportunity to up-date my system and, due in part to time constraints, decided try receivers rather than the tried and true separates.

I have always had an Onkyo receiver connected to my home entertainment system, so I decided to buy an Onkyo TX-SR706 for my main stereo system. I cannot begin to tell you how happy I am that I did. The SR706 receiver has preformed far above my sonic expectations, and the Audyssey system makes set-up and equalization as simple as pushing a few buttons. I was so impressed with the SR-706 that I purchased TX-SR606 (that I have been equally impressed with) and up-dated my home entertainment system. I have not experienced the intermittent sonic dropouts that other users have reported, and would strongly recommend the TXSR706, or its little brother SR606, to anyone looking to buy a home entertainment or stereo receiver.

Remote Control
Input and Output Notes


WRAT (Wide Range Amplifier Technology): This technology uses low-negative-feedback circuit topology for accurate signal reproduction, improved dynamic signal-to-noise ratio, and better delivery of power peaks.

Digital-to-Analog Converters (DACs): To decode and playback high-resolution recordings, this receiver is equipped with 192kHz/24-bit DACs for all channels.

Component Video Switching: In addition to HDMI, composite video, and S-Video switching, this unit can switch between high definition component video sources. There are 2 component video inputs and 1 component video output. The component video inputs and outputs have a bandwidth of 5Hz to 50MHz.

HDMI v1.3a Repeater: The TX-SR706 has four HDMI v1.3a inputs and one HDMI v1.3a output for connecting DVD players, HDTV set-top boxes, and other video components to your TV or projector. The receiver's HDMI circuitry allows the receiver to output an HDMI audio signal from its speaker outputs and HDMI out so you don't have to run and additional analog or digital cable. The HDMI inputs are also compatible with DVI, so TVs and displays with a DVI input can be connected by using an HDMI-to-DVI adapter cable, along with audio cables. The receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture. The HDMI inputs can accept and switch 480i, 480p, 720p, 1080i, and 1080p signals to a TV, monitor, or projector. Each of the HDMI inputs can be assigned to any of the five rear panel A/V inputs (DVD, VCR/DVR, CBL/SAT, Game/TV). The receiver's HDMI input also supports the following functions.

  • Audio Formats: 2-channel linear PCM (32-192 kHz, 16/20/24 bit); Multichannel linear PCM (up to 7.1 ch, 32-192 kHz, 16/20/24 bit); and Bitstream (DSD, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD High Resolution Audio, DTS-HD Master Audio).
  • xvColor: Increases detail and color space when watching movies on your television from an external device connected by HDMI through the TX-SR706.
  • Auto Lip Sync: The Lip Sync function can automatically synchronize HDMI audio and video that has gotten out of sync due to the complex digital video processing being performed by your HDMI-compatible TV. With HDMI Lip Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the AV receiver.
  • HDMI Control: This function allows CEC-compatible components or RIHD-compatible components connected via HDMI to be controlled with the TX-SR706.
  • Power Control: This feature allows you to link the power functions of CEC-compatible components or RIHD-compatible components connected via HDMI.
  • TV Control: This function enables you to control this AV receiver from an RIHD-compatible TV connected via HDMI.

HDMI Upconversion With Upscaling: The Onkyo TX-SR706 will convert incoming analog composite video, S-video, and component video signals to HDMI so you can connect all your video sources through the receiver and then to your TV via HDMI to give you the best picture quality possible. Using Faroudja DCDi Edge Technology, the receiver has the ability upscale incoming analog and digital video signals up to 1080p. You can specify the output resolution for the receiver's HDMI output and have the AV receiver upconvert  and upscale the picture resolution as necessary to match the resolution supported by your television. You can select from 480p, 720p, 1080i, 1080p, Auto or Through.

Bi-Amping Front Speakers: The Front L/R and Surround Back L/R terminal posts can be used with front speakers and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for the front speaker, providing improved bass and treble performance. When the bi-amp feature is used, the AV receiver is able to drive up to 5.1 speakers in the main room.

Speaker Impedance: There is a menu adjustment for minimum speaker impedance. Options are 6Ω (for speakers 6 to 16-ohms) and 4Ω (for speakers 4 or 5-ohms).

Dual-Zone Capability: You can use two speaker systems with the TX-SR706 receiver - a surround-sound speaker system up to 7.1 channels in your main listening room (Zone 1), and a stereo speaker system in a second room (Zone 2). The Zone 2 outputs allow you to enjoy one source in your main listening room, while other sources play in remote rooms. Depending on how you configure the receiver, using Zone 2 will require an additional amplifier and speakers, a set of powered speakers, or simply a set of non-powered speakers located in a remote location. You can connect the dedicated Zone 2 stereo RCA line outputs to a receiver/amplifier or powered speakers in one room while powering a 7.1-channel speaker system in the main room; the output level of the RCA line outs for Zone 2 can be switched from fixed for variable, so they can be connected to an amplifier or powered speakers equipped with or without a volume control. You can also connect a pair of speakers to the receiver's dedicated Zone 2 speaker terminals and simultaneously power a 5.1-channel speaker system in the main room. When the Zone 2 speaker terminals are turned on, the Surround Back speaker outputs do not work. When the Zone 2 speaker terminals are off, the Surround Back speaker outputs work as normal. The Zone 2 speaker output volume setting can be controlled with the remote. Only analog sources can be played in Zone 2.

iPod Compatible: The DS-A2x or DS-A3 Remote Interactive Dock for iPod (item # 580DSA2X and 580DSA3) provide an interface between an iPod digital media player and Onkyo TX-SR706. Once the iPod is docked you can control basic functions such as volume control, play, stop, and skip via the Onkyo system's RI-compatible wireless remote control. The dock also charges the battery in the iPod, and allows you to view digital photos and video on an Onkyo home theater system.

Satellite Ready: The Onkyo TX-SR706 features proprietary ports on the rear panel for XM and Sirius Satellite Radio connection. In addition to the following optional satellite tuners needed (sold separately), you will need a subscription to XM and/or Sirius Satellite radio. 

  • XM Satellite Radio Ready: The receiver can be connected to the optional XM Home Mini-Tuner and Home Dock (part # 700XMTUNPK, sold separately), allowing you to receive XM Satellite Radio through the TX-SR706. You can search XM radio stations by Channel, Category or Direct Tuning. You can also choose to display the following XM information on the receiver's display - Channel Name, Channel Number, Category Name, Artist Name or Song Title.
  • Sirius Satellite Radio Ready: The TX-SR706 can also be connected to the optional SiriusConnect Home Tuner kit (part # 607SCH1, sold separately), which allows you to receive Sirius Satellite Radio through the receiver. You can search Sirius radio stations by Channel, Category or Direct Tuning. You can also choose to display the following Sirius information on the receiver's display - Channel Name, Channel Number, Category Name, Artist Name or Song Title.

Multi-Channel Input: The receiver is equipped with a 7.1 multi-channel input for compatibility with external decoders or high resolution audio players such as DVD-Audio or SACD. The input consists of left front, right front, center, subwoofer, left surround, right surround, left surround back and right surround back RCA inputs.

Audyssey MultEQ: MultEQ detects speakers, and then sets levels, delays and crossovers, as well as measuring room acoustics. Using the receiver interface, it takes up to 6 measurements around the listening area and uses high-resolution equalization filters for satellites and subwoofers. MultEQ covers both frequency response and time domain (where most of the problems lie) across the entire listening area. The results are immediately obvious - a clear, well-balanced and natural sound. With the supplied speaker setup microphone, Audyssey MultEQ can measure the number of speakers connected, their sizes, crossover frequencies, and distances from the listening position and calculate the optimal speaker settings for you automatically. The supplied microphone is approximately 1-15/16" in diameter, 7/8" tall, and has a 19-3/4' cable that plugs into the front of the receiver. There is a threaded insert on the bottom of the microphone so it can be mounted on a tripod for accurate listening position placement. If you wish to setup the speakers manually, you can follow the procedure for Speaker Configuration.

  • Subwoofer Setup: You can select whether or not you will be connecting a powered subwoofer to this receiver and the low-pass crossover point for the subwoofer - 80Hz, 90Hz, 100Hz or 120Hz. You can set the level of the LFE channel individually for Dolby Digital, DTS and multichannel PCM sources.
  • Speaker Crossover: This receiver has a built-in high-pass crossover for each speaker in the system. This setting is available when the subwoofer is set to Yes. The frequencies that you can choose from are 40, 50, 60, 80, 100, 120, 150, 200 Hz or Full Range. Frequencies lower than the set crossover point are output by the subwoofer.
  • Speaker Distance: The distance from your listening position to each speaker can also be set manually. The front speaker distance can be set from 1 to 30 feet in 1-foot increments. The center and subwoofer settings can be up to 5 feet more or 5 feet less than the distance you set for the front speakers (30 feet max). The settings for the surround left, surround right, surround back left, and surround back right speakers are each individually adjustable, and they may be up to 5 feet more or 15 feet less than the distance you set for the front speakers (30 feet max).
  • Speaker Levels: You can manually adjust the level of individual speakers between -12dB and +12dB; -15dB to +12dB for the subwoofer.
  • Equalizer: You can adjust the receivers 7-band equalizer (63, 160, 400, 1000, 2500, 6300, and 16000 Hz) for each speaker manually from -6 to +6dB in 1dB increments.

Bass And Treble: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-SR706 from -10 to +10 dB.

  • Dimension: allows you to move the sound field forward or backward
  • Center Width: allows you to adjust the width of the center channel

Center Image: In the DTS Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).

Re-Equalization Circuitry: Re-EQ (re-equalization) corrects a soundtrack with high frequency response that's too harsh, compensating for the fact that sound mixed for large theaters may sound too bright when played back through speakers in the home environment. This can be set to either On or Off.

Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High.

Note: This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.

Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics. Dynamic EQ selects the best possible frequency response and surround levels moment-by-moment as volume is changed. The result is bass response, tonal balance and surround impression that remain constant despite changes in volume. Audyssey Dynamic EQ combines information from incoming source levels with actual output sound levels in the room, a prerequisite for delivering a loudness correction solution. Audyssey Dynamic EQ works in tandem with Audyssey (2EQ, MultEQ, MultEQ XT) to provide well-balanced sound for every listener at any volume level.

Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz and analog input signals.

AV Sync: Occasionally the audio and video signals are not properly synchronized, typically when using a progressive scanning DVD player. You can correct this by delaying the audio; options are 0 (no delay) to 250 milliseconds, in 5 millisecond steps.

IntelliVolume: The IntelliVolume setup function allows you set a volume correction value in the range of -12dB to +12dB, in 1dB increments, for each source to prevent large jumps in volume when switching from one source to another. This feature eliminates the inconvenience of manually readjusting the volume control each time you switch from a source with a weak signal to a source with a strong signal and vice versa.

Volume Setup: The receiver volume can be configured in the following ways:

  • Maximum Volume: prevent the volume from being turned too high by setting a maximum level for Zone 1 or Zone 2; specify any volume in the top half of the volume range
  • Power On Volume: specify the volume setting when the receiver is turned on for Zone 1 or Zone 2; specify any volume or Last to use the same level that was used when the receiver was turned off.
  • Headphones Level: set the headphone volume relative to the main volume, choose a level between -12dB and +12dB

Picture Adjust: Using Picture Adjust, you can adjust the picture quality of the receiver's monitor output and reduce any noise appearing on your connected television display. You can adjust the following picture adjustments - Picture, Brightness, Contrast, Hue, Saturation, Edge Enhancement, and Noise Reduction.

On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The joystick/enter button on the remote makes display navigation and setting adjustment simple and convenient. The setup OSD is passed through HDMI only.

Display Information: You can display various information about the current input source such as Input Source and Volume; Signal Format or Sampling  Frequency; and Input Source and Listening Mode.

Name Edit: You can enter a custom name for each individual input selector and radio preset for easy identification.

Display Dimmer: The display illumination includes the green alphanumeric display and a blue ring around the volume knob. You can dim the display as follows: Normal and Volume light on, Normal and Volume light off, Dim and Volume light off, and Dimmer and Volume light off.

Sleep Function: From the remote, you can set the unit to automatically turn off after as much as 90 minutes or as little as 10 minutes; choices are presented in 10 minute increments.
