gy inefficient.

These days, multi-channel receivers are much smarter about energy use and multi-channel audio is ubiqutous. So after replacing my favorite plasma display, I decided to use some of the power saved by switching to OLED to get surround sound back. My ancient SONY 5.1 receiver used to suck a constant 300W of wall power whether the volume was at maximum or 1 dB above mute. This 7.1 (or 5.1.2) amplifier, which has a rated energy consumption peak of 600W draws nowhere near that at THX reference volume (82 dB). The most I've measured the receiver draw continuously is 86W; if it ever came anywhere near the 600W number listed in the specifications it'd overload the UPS in my A/V rack and I'd be writing a very different review right now ;)

Basically what you're buying here is a receiver and speaker bundle adequately balanced to earn THX I/S Plus certification (viewing distance should be ~6-8 feet). I'm not one for flashy brand names, but THX is a name I trust from my experience in video and certifying theater audio performance is the entire reason the brand was created. Matching receiver and speakers for room size as determined by certification class makes going multi-channel almost as effortless as buying a soundbar and it is a great thing that consumer THX certifications exist.

The bundled front / center channel speakers are pretty much what I expected, but I'm very impressed with the satellite speakers; they're full range. I was pleasantly surprised to hear just as much range of detail out of the surround channels as the front. That said, they're much heftier than many satellite speaker stands are designed to accommodate (8 lbs each) and you need to be careful if you go with a floor stand solution because without adequate base weight these stands are very likely to tip over. I picked up a pair of these http://www.amazon.com/LOCH-SS-1-Speaker-Stands-set/dp/B00W3S8XTM/ to hold the satellites, they have enough of a counter-weight in the base that they are less prone to tip over than other stands I tried (there's a very good reason these stands are rated for weight, and it has nothing to do with the strength of the stand). The keyhole mounting bracket on the satellite speakers doesn't quite fit the hardware supplied with those stands, but if you reverse the thumb screw and move it 1 notch above where it's engineered to go you can attach these speakers securely. I'm only mentioning this here rather than a separate product review because there are a couple of other satellite stands on the market with identical mounting hardware designs but less of a counterweight on the bottom (which is why they tip over)... attaching these satellites to any of those stands is a bit awkward but can be done.

If you're looking at this receiver's HDMI 2.0 4K/60 Hz and HDCP 2.2 support and thinking that buys you a little bit of future proofing, I would strongly suggest a bit of caution here. It's absolutely true that the receiver is HDCP 2.2 compliant (you will need this for Ultra HD Blu-Ray) and will allow you to pass through a 4K 60 Hz signal, but there's a slight caveat that plagues a lot of HDMI 2.0 devices right now. This caveat is the maximum pixel clock (how much data the cable can carry), and it is identical to HDMI 1.4 (340 MHz) on this receiver. There's a sort of hidden gotcha with HDMI 2.0, where the 600 MHz pixel clock (arguably its most important improvement over 1.4) is actually an optional feature. A 600 MHz HDMI 2.0 device can do 4K 60 Hz using traditional color encodings such as YCbCr 4:2:2 or YCbCr 4:4:4 / Full Range RGB (what PCs prefer to output), but to do 4K 60 Hz with a 340 MHz pixel clock requires sampling color at 1/4 the resolution of brightness. HDMI 2.0's 4:2:0 subsampling creates visible color artifacts on just about anything rendered on a PC because you effectively get 4K resolution for brightness and 1080p for color. High contrast text, narrow fonts and thin lines in graphical user interfaces are almost impossible to make out clearly at 4:2:0, so if you plan on doing anything non-TV/movie related at 4K 60 Hz, don't route the signal through this receiver.

I have a very high-end PC that plays games at 4K, and what I wound up doing to integrate this receiver into my setup without sacrificing image quality required a bit of ingenuity. I have the HDMI 2.0 output on one of my GPUs connected directly to my TV (allows full range 24-bit RGB at 4K/60 Hz instead of the nasty YCbCr 4:2:0 HDMI 2.0 hack I discussed earlier), and I have a DisplayPort to HDMI adapter that feeds an uncompressed 7.1 audio signal to the receiver. In lieu of this, you might also be able to pickup a dedicated sound card with S/PDIF output and either DTS Connect or Dolby Digital Live encoding support in order to get 6.1 or 7.1 audio to the receiver while playing games at 4K 60 Hz. It's not ideal, but that may be necessary on some setups if you don't have enough HDMI and/or DisplayPort outputs on your GPUs. I had to resort to this prior to picking up a DisplayPort to HDMI adapter (my GPUs only have 1 HDMI output, but 3 DisplayPort outputs).

Minor videophile and gamer annoyances aside, there's some undeniable value in this system for a small sized room (the THX certified 6-8 foot viewing distance means this would be best paired to a 55" or smaller display). Incidentally, if you're interested in the THX certified speaker package by itself you can get it for ~$400 less (SKS-HT993THX) - you might use the savings to buy a reiver that handles 4K signals better than this one does (I suspect they all handle 4K poorly at the moment though, HDMI 2.0 and most other UHD related standards are poorly implemented across all consumer electronics right now).

For a bit of scale, I have attached an image that shows the speaker package against a 55" display. You can arrange L/C/R horizontally underneath a 55" or larger display if you have no room on the sides... I did that originally and used the AccuEQ room calibration to fix up the center channel, but eventually I just decided to stack my second display on top of the subwoofer.

目前，多频道接收机在能源使用方面更加智能化，而多声道音频则是无可比拟的。所以在更换我最喜欢的等离子显示器之后，我决定使用切换到OLED模式节省下的一些电能来获得立体环绕声。我的古老的SONY 5.1接收机，无论音量是最大还是只比静音高1 dB，都能使用300W的功率。这个额定功耗峰值为600W的7.1（或5.1.2）扩音器在THX参考音量（82 dB）左右的时候能源利用率也很低。我测得的最大的接收功率是86W;如果它接近规格中列出的600W数字，它会使我的A / V机架中的UPS过载，然后我现在就会正在写一个非常不同的评论;）

基本上你在这里购买的是一个接收器和扬声器的充分平衡，以获得THX I / S Plus的认证（距离应该是6-8英尺）。我不是热衷于一个华而不实的品牌的人，但是THX是我在视频播放器的经验所得和很信任的品牌，而音乐表演得到认证是品牌创立的全部理由。根据等级确定的房间大小，获得接收器和扬声器的匹配使得多频道几乎像买条形音箱的时候那样轻松，消费者THX认证的存在是一件好事。

捆绑式的前/中置声道扬声器几乎和我所期望的差不多了，但卫星扬声器给我留下了非常深刻的印象。他们是全方位的。我很惊喜地听到很多关于前方环绕声道的细节。据说，它们比许多卫星扬声器支架的容量要大得多（每个8磅），不过您使用落地支架解决方案时需要小心，因为没有足够的基重，这些支架很可能会翻倒。我拿起一对这样的卫星扬声器，他们有足够的配重，也比我尝试过的其他展位更不容易倾倒（这些看台按重量比率来算是一个很好的理由，这与展台的强度无关）。卫星扬声器上的锁孔安装支架与这些支架随附的硬件不太匹配，但是如果反转拇指螺钉并将其移动到设计位置的上方的1个凹槽处的话，则可以安全地连接上这些扬声器。我只在这里提到这一点，而不是单独的产品评论，因为市场上还有一些其他的卫星支架，它们的安装硬件设计完全相同，但底部的配重较少（这就是为什么他们会倾倒）这些卫星扬声器对这些展台中的任何一个都有点尴尬，但还是可以做到。

如果您正在查看接收机的HDMI 2.0 4K / 60 Hz和HDCP 2.2支持，并且认为这会给您以后选择带来一些标准的话，那么我强烈建议您在此谨慎一些。确实，接收机符合HDCP 2.2标准（您将需要Ultra HD蓝光光盘），并且可以让您通过4K 60 Hz信号，但是现在有一点需要注意的是现在很多HDMI 2.0设备。这个警报用的是最大的像素时钟（电缆可以携带多少数据），并且与这个接收器上的HDMI1.4（340MHz）相同。 HDMI 2.0有一个隐藏的问题，其中600 MHz的像素时钟（可以说是1.4以上版本最重要的改进）实际上是一个可选功能。一个600 MHz的HDMI 2.0设备可以使用YCbCr 4：2：2或YCbCr 4：4：4 /全范围RGB（PC更喜欢输出）等传统颜色编码来实现4K 60 Hz，而4K 340兆像素的时钟需要使用1/4的亮度分辨率的采样颜色。 HDMI 2.0的4：2：0子采样在PC上渲染的任何东西上都会产生可见的彩色伪像，因为您可以获得4K分辨率的亮度和1080p的色彩。图形用户界面中的高对比度文本，窄字体和细线几乎不可能在4：2：0清晰地显示出来，所以如果您计划在4K 60 Hz下执行与非电视和电影相关的任何操作，请勿让路由信号通过这个接收器。

我有一台非常高端的个人电脑，可以在4K上玩游戏，而我最终所做的就是将这个接收器集成到我的设备中，而不牺牲图像质量，这需要一点创造力。我有一个直接连接到我的电视的GPU上的HDMI 2.0输出（允许在4K / 60赫兹的全范围的24位RGB，而不是我讨论过的令人讨厌的YCbCr 4：2：0 HDMI 2.0黑客）一个DisplayPort转HDMI适配器，为接收器提供一个未压缩的7.1音频信号。取而代之，您也可以拾取带有S / PDIF输出的专用声卡，以及支持DTS Connect或Dolby Digital Live编码，以便在以4K 60 Hz频率播放游戏时获得6.1或7.1的音频。这并不理想，但如果您的GPU上没有足够的HDMI和/或DisplayPort输出，则在某些设置中可能需要这样做。在拿起DisplayPort转HDMI适配器（我的GPU只有1个HDMI输出，3个DisplayPort输出）之前，我不得不求助于此。

对于小型的视频发烧友和游戏玩家来说，这是一个不可否认的价值（THX认证的6-8英尺的观看距离意味着这可以与55英寸或更小的显示器最好的配对）。顺便说一句，如果你对THX认证的扬声器包装本身感兴趣，你可以得到价格低于400美元的同类产品（SKS-HT993THX） - 你可以用节省的钱购买一个比这个更好的4K信号处理器（我怀疑它们在4K、在目前HDMI 2.0和其他大多数的UHD相关标准上以及在所有消费类电子产品中的实施效果不佳）。

对于一些小规模的作品，我附上了一个显示55" 显示屏的扬声器包装的图像，如果你的侧面没有空间，你可以把L / C / R水平地放在55”或更大的显示器下面。最初我这样做了，并使用AccuEQ房间校准来修正中心声道，但最终我决定将第二台显示器叠放在低音炮的顶部。

on the ceiling, yet the size that came with the other unit was just too big. Then, by luck, this new setup came out. It has everything I needed. Just 5 speaker enclosures with the extra 2 being apart of the fronts. They point up and bounce the sound off of the ceiling. Look up Dolby Atmos enabled speakers and you'll see what a deal it is to get them with this package.

Setup is stupid easy. Clearly labeled connections on the back of the receiver. All of the speaker wire is also color labeled. The AccuEQ Room Acoustic Calibration is nice.

More inputs that I will ever use.

If your TV is new enough, it can either control the volume of the TV or keep sound from going to it completely to only use the surround sound. It can also be programmed to power on and off when you turn the TV on/off. I was also able to program my satellite box's remote to control the receiver without having to switch the remote settings back and forth to AV1/AV2.

Bass speaker THUMPS and I only have it turned up to half way!

For most people, including myself, it will seem weird that you have to turn the volume setting up into the 50's-60's after setup, even though there is really nothing wrong with it. There is an option to increase the volume output for each device connected and you can vary that amount for each device. Let's say that your satellite box has a comfortable level around 30 while watching TV. Then you try to stream a movie from Amazon with your PS3/4/Xbox one and the volume is really low (we all know this happens). Well, instead of cranking up the volume of the receiver each time, you can go into Setup-->Source-->IntelliVolume and increase the volume for just that device. You must be currently listening to the device you are changing at the time though.

安装非常简单。在接收器背面标记清楚连接位置。所有的扬声器电线也是彩色标记的。 AccuEQ的室内声学校准非常好。

更多的输入，我将会持续使用。

如果您的电视足够新，它可以控制电视的音量或保持完整的声音，只使用环绕声。当您打开或者关闭电视机时，也可以通过编程来打开和关闭电源。我还能够通过编程使我的卫星箱可以通过遥控器来控制接收器，而不必将遥控设置来回切换到AV1 / AV2。

低音扬声器THUMPS，我只用了它最高音量的一半！

对于包括我自己在内的大多数人来说，这看起来很奇怪，你必须在设置后，将音量也调整到50到60之间，即使它没有任何问题。可以选择增加连接的每个设备的音量输出，并且可以改变每个设备的音量。假设您的卫星电视在观看电视时的音量舒适水平在30左右。然后你试着用PS3 / 4 / Xbox从亚马逊流出一部电影，音量非常低（我们都知道这发生了）。那么，这不是每次启动接收机的音量，你可以进入设置 - >来源 - > IntelliVolume，并增加该设备的音量。您当时必须一直用耳朵听着您正在调整的设备。

is little room for future upgrading. The sub is connected with speaker wire and not a sub cord. The speakers are also crimp clips and not banana plugs. There are compatible speaker kits that are crimp clips, but the good ones are banana plugs. Do yourself a favor and buy a spool of 14 gauge speaker wire. The included wire is 22 gauge and is a joke. For the price and for what you get I do not blame Onkyo for the substandard speaker wire. The remote works well up to about 10 feet away and then it is a gamble. Also, for some reason, the remote eats batteries. I have to replace mine every several months but I also use these units every day.

As a side note, the unit I just ordered arrived looking brand new. No scratches, properly packaged, packing material in all the correct places. After hooking everything up I, at first, could not get the speakers to work. I tried every sound parameter, doubled and tripled checked all my wires. As a last hope effort, I reset the unit to factory settings and it instantly worked after powering back on. I have not had any issues since the day I set it up. I do not think it was pre-owned and I could have easily hit something on the remote in the beginning without realizing it. If you run into the same situation, try resetting the unit before contacting tech support or returning. Tech support can be a headache as well.

作为一个侧面说明，我刚刚订购的配件，是我找到的全新的。没有划痕，包装很好，所有包装材料都在正确的地方。把所有东西都连接上之后，起初扬声器不能工作。我尝试了所有的声音参数，加倍仔细的检查了所有的电线。为了最后尝试一下，我将设备重置为出厂设置，并在重新开机后立即开始工作。自从重启之后，我就没有任何问题了。我不认为这是二手的机器，我可以很容易地在遥远的距离碰到一些难题，但却没有想过到这一点。如果遇到同样的情况，请在联系技术支持或退货之前尝试重置设备。技术支持也是一件令人头痛的事情。
