What is a 7.2 home theater system?
A 7.2 home theater system arrangement consists of seven speakers and two subwoofers. It will improve your overall viewing experience in that you can hear sound originating from different directions. Also, you may get higher audio quality because of the increased number of speakers located all over your room. This improves the sound distribution and reduces the overall pressure on every speaker. As a result, each of them produces a narrower range of sounds it can do better, giving a clearer immersive experience.
The 7.2 configurations can be quite expensive for all its benefits, especially if you’re using premium components. Installing such a system can also be quite complicated and take a lot of time. Because to achieve optimal sound quality, you need to place your speakers and subwoofers correctly. Of course, you cannot forget about your room’s acoustic parameters.
All things considered, a 7.2 home theater system is a good option for anybody seeking a premium audio experience. The advantages of genuine surround sound, improved audio quality, and Dolby Atmos compatibility makes it a worthy purchase, even if it can be pricey and difficult to set up.
How to choose a 7-channel receiver
So, before we get to the review of receivers, let’s focus on the main points you should consider when choosing a model of this configuration.
How much power do you need
That’s a very slippery question. Why? Because power is actually not as important an indicator as it may seem at first glance. First of all, a heavy-duty receiver will not make you happy if it starts to “wheeze” at maximum volume and makes other not-quite-pleasant sounds. Secondly, you do not plan to constantly use your audio equipment at maximum volume. Thirdly, you need to evaluate several parameters together: the size of your room, the quality of the speakers, the power, and THD.
For 7-channel receivers, the optimum power is in the range of 75-100 watts. This is quite enough for a uniform sound filling of a room of about 300-400 square feet. A distortion factor of 1% or more for receivers is considered bad. For example, a receiver model with 75 watts (THD – 0.08%) can sound identical or even louder than a receiver with 100 watts (THD – 0.8%). And most importantly, the sound will definitely be “cleaner” at maximum RPM.
HDMI inputs and 4K/8K
Having multiple HDMI inputs is something you should pay close attention to. And here, the simple rule “the more, the better” works. After all, the receiver is a device that should provide communication with other components of your multimedia system. Therefore, analyze what equipment you already have and what you are planning to buy and, based on this, determine the necessary minimum of connectors that the receiver should have.
Pay attention only to HDMI version 2.1 ports, as they have the latest functionality (eARC, HDCP 2.3, CEC, and advanced features for gamers), and you won’t need to upgrade your receiver for a long time.
Another important aspect is the receiver’s support for 4K/8K video resolutions and the ability to upscale to these quality levels. Yes, there isn’t much 8K video content out there yet, but you have to think ahead. Also, technologies like Dolby Vision, HDR, HDR10, and HDR10+ can seriously improve picture quality. Many 7K models usually support some of these. It’s worth checking your TV to see if it can handle these technologies and screen resolutions.
Dolby Atmos and DTS:X
Yes, surround sound is the highest priority among other AV receiver features. Surely, you want to watch the world’s blockbusters with incredible sound. So what to look out for?
In addition to working with the basic 3-D sound formats, many modern 7-channel receivers support the now very popular Dolby Atmos and DTS:X. Indeed, these technologies provide a deeper immersion in the soundstage and configure the effect of a real movie theater when the sound surrounds you from all sides.
But you should realize that a 7.2 configuration (or 5.2.2 for Dolby Atmos) cannot fully utilize the full capabilities of Dolby Atmos and DTS:X. That’s why I recommend you pay attention to receiver models that support their virtual versions (Dolby Atmos Height Virtualizer and DTS Virtual:X).
Multi-room audio and wireless connection
Typically, 7-channel receivers have more wireless connectivity options than their 5-channel counterparts. They are equipped with built-in Wi-Fi and Bluetooth. In addition, many modern devices provide support for DTS Play-Fi, AirPlay 2, and Chromecast, as well as can work with aptX, SBC, or AAC codecs for Bluetooth 4.2. Such capabilities positively impact the overall quality of lossless signal transmission in high quality.
The availability of advanced wireless capabilities allows you to build audio systems for multi-room broadcasting. You can turn your home or apartment into unique audio zones with HEOS (Denon, Marantz), MusicCast (Yamaha), and Sonos multi-room technologies.
How much do 7.2 AV receivers cost
The price depends on a number of parameters, such as the manufacturer, the capabilities of the device, and the availability of additional features. But on average, the price for 7-channel AV receivers ranges from 450 to 1500 dollars. So expect that for 1000$ you will be able to buy quite a decent 7-channel receiver.

Sony STR-DH790 – budget
The Sony STR-DH790 is a 7.2-channel home theater AV receiver released in 2018. Sony positions this model as a versatile and affordable option for people who want to join the world of high-end audio. The device is part of Sony’s entry series of AV receivers, which includes models designed to balance affordability and a rich set of technologies. The STR-DH790 is a successor to the popular STR-DH770 model and offers several upgrades over it.
Without a single doubt, Sony always aspirated to bring new notes into the niche of AV receivers. The STR-DH790 offers to a certain extent unusual design for the receiver. It has a compact size, measuring 17″ x 5-1/4″ x 11-3/4″, and a weight of 16 lb 6 oz. The front panel is elegant, featuring large display and control surfaces shifted to the side. Thus, this model looks non-standard, stylish, and, most importantly, practical.
The Sony STR-DH790 supports from 6 up to 16 ohms speakers. Additionally, the device can serve as a 5.1.2 receiver with separate decidable channels and 7 channel output of 145W per single one (6 ohms, 1kHz, 1ch THD 0.9%). The power with 8 ohms speakers is going to be a bit lower. The manufacturer guarantees the sound quality both with 6 and 8 ohms speakers. The unit features various sound fields, including 2ch Stereo, Direct, Multi Ch Stereo, Dolby Surround, Neural: X, Front Surround, Audio Enhancer, and Headphone 2ch.
The interface offers 4 HDMI inputs with HDCP 2.2 support, a single HDMI output, and audio input options for optical, coaxial, and analog connectors. The amplifier also features a pre-out subwoofer, headphone output, and a USB connector. It also features Bluetooth connectivity but lacks Wi-Fi.
Talking about video features, those include the ability to transmit 3D signals over HDMI and 4K 60p 4:4:4. The device also has A/V SYNC. Additionally, the Sony STR-DH790 supports ARC and eARC. The device also features BRAVIA SYNC helping to use a single remote. Finally, this unit offers HDR technology, including HDR10, HLG, and Dolby Vision compatibility. Yet, it doesn’t come with HDR10+.
The STR-DH790 does not graze the rear with its audio features, as it has the latest audio codecs, including Dolby Atmos and DTS:X. Additionally, the STR-DH790 offers the following lossless codecs FLAC, ALAC, and DSD files. I also enjoyed Sony’s proprietary S-Force PRO front surround sound technology. Surely, it’s far from an honest 5.1 or 7.2 setup, but even with two speakers, it can still deliver a miracle of surround-like sound.
When testing the STR-DH790, I notice stunning clarity and accuracy in reproducing audio. Action movies, emotional romantic comedies, noisy older movies – all sounded well and greatly balanced with a defined sound stage. Bass sections were another miracle I enjoyed – free from distortion, and punchy lows are what one needs to enjoy a movie. The unit also showed itself capable with music. Due to its supreme power, it didn’t max out even a single time. Also, multiple sound adjustment features allowed me to make the music sound exactly as I love without making it seem unnatural.
Overall, the Sony STR-DH790 is an impressive 7.2-channel home theater AV receiver that offers an excellent balance between affordability and advanced features. It has an interesting design, featuring a compact size and weight while still being fully packed with capabilities. This model boasts numerous sound fields and supports various audio codecs making it the best budget 7.2 home theater receiver.

The RX-A2A is the successor to the popular RX-A680 model and offers several upgrades over it, including advanced technologies. So, here I uncover the truth about Yamaha RX-A2A and compare it to some of its main competitors.
The receiver comes with a typical Yamaha design, with a large control knob right in the middle, a display shifted to the side, and a smaller control surface located even further left. As for me, the other side looks somewhat empty. Yamaha uses quality materials to build every device – the RX-A2A is no exception. It has a relatively compact size, measuring 17-1/8″ x 6-3/4″ x 14-7/8″ and weighing in at 22.5 pounds. Overall, the look of this model is pretty disputable, and it is also pretty average in size and weight.
The Yamaha RX-A2A offers 100W with 8 ohms speakers, 0.06% THD per channel. It doesn’t hold a power record but is sufficient for small to medium rooms. The built-in DAC module is 384 kHz / 32-bit BB PCM5102A. This chip is famous for accuracy and fidelity. Theoretically, this should mean that the RX-A2A is a universal unit for all tasks, but is it?

At the same time, in my tests, it showed itself to be less impressive but still delivered quality. First of all, I enjoyed the light crispness of sound in movies. Combined with a clean special effect, this crisp sound adds points to the atmosphere.
On the other hand, in music, it truly felt that the unit should avoid pumping so much bass because it felt overwhelming. So yes, I managed to adjust it via built-in modes. Still, this shouldn’t be the case, especially when discussing an out-of-the-box solution.
Overall, the Onkyo TX-SR494 is a reliable and durable AV receiver with plenty of features that make it a good choice. However, it may not be an option for music enthusiasts as it lacks certain features, is not optimized enough for this, and has fewer connectivity options than other models.

Pioneer Elite VSX-LX105
Last but not least comes Pioneer Elite VSX-LX105. This 7.2-channel unit came to market as the company’s attempt to deliver a powerful and immersive sound to new customers at a fair price. Pioneer has its name for creating high-quality products, so the Elite VSX-LX105 was an obvious choice for this review.
The Pioneer Elite VSX-LX105 is a well-designed device with a solid chassis and a quality look and feel. Even despite its outdated design layout, the unit still looks stunning. The face of the unit features a convenient display screen, a volume dial, and many control buttons for convenient access to the receiver’s capabilities. The chassis is composed of high-quality materials, making it sturdy and assisting in heat dissipation. Talking about sizes WHD: 17-1/8 x 6-13/16 x 14-9/16 inches, and weight is 21.6 lbs.
The Pioneer Elite VSX-LX105 AV receiver can drive as much as 100 watts per channel (with 8 ohms speakers, 20 Hz-20 kHz, THD 0.08%, 2ch Driven FTC) and 210 watts per channel (with 6 ohms ones, 1 kHz, THD 10%, 1ch Driven). The DAC chip is 192 kHz/24-bit D/A. The unit comes with numerous features, including Dolby Atmos, DTS:X, and others. It also has several Advanced Surround Modes, allowing you to adjust them.
The Pioneer Elite VSX-LX105 offers six HDMI 2.1 inputs and 2 outputs (one for the main display and one for a sub/zone 2). They can work with 8K/60p and 4K/120p content. The receiver also has a USB input, an MCACC setup MIC input, an Ethernet, phono, and digital coaxial and optical ones. It also offers gold-plated audio, a headphone jack, and a subwoofer. Additionally, the unit has FM/AM antenna inputs.
The model supports HDMI 2.1 with 8K resolution, VRR, ALLM, QFT, and DSC. It also supports HDR10+ and HLG. The device can display 8K/60p, 8K/30p, 4K/120p, 4K60p, and BT.2020 color, DeepColor, LipSync, and HDCP 2.3. Additionally, it is compatible with Dolby Vision and supports 8K upscaling.
During testing, the device performed well, providing a clear and bright sound in movies. Altogether, I am very satisfied with the performance of this receiver, but there is still a fly in the ointment. Thus, I noticed that even despite its great power, it lacks bass depth in music. Sometimes this shows itself in movies, but it is almost always clearly seen in music. I managed to fix this via a built-in subwoofer tuner to make the sound deeper. However, if your woofer has no controls, then you definitely may struggle with this.
In conclusion, the Pioneer Elite VSX-LX105 is a quality model with a worthy list of technologies. Pioneer also doesn’t seem to save on quality, so it feels rigid and solid. At the same time, the problem with bass adds inconveniences to using this 7.2 surround sound receiver. It may be fixed in no time by adjustments on your subwoofers, but what if you don’t have that option?

FAQ
Is 7.2 surround sound worth it?
The sound quality of a 7.2 surround sound system is better than that of a 5.1 surround sound system because this configuration not only produces sound effects from different directions but also has higher bass effects and depth perception. Therefore, if you have a 5.1 receiver, the transition to 7.2 will be for you like a transition to the Super League from an amateur team.
