Onkyo TX-SR3100 5.2-Channel AV Receiver - Dolby Atmos, Dolby Height Virtualizer, Dolby Vision and More

The first emotions when I received this receiver: How huge and heavy it is. After I connected it temporarily to my old speakers from the old receiver, and decided to listen to Dolby Atmos music from Apple Music and I was very delighted! My speakers from 2008 from budget LG acoustics began to sound much cleaner, and the Dolby Atmos sound amazed me. I really liked the way the receiver distributes the sound to all the speakers, each speaker has a separate signal, which gives the sound that you are on stage and the artist is standing in front of you and singing. I also can't help but mention games and movies. The sound is divine both there and here. In the game Until Dawn, for example, the sound gave even more atmosphere so much that I did not go into this game without the speakers turned on. When watching movies, the sound is as if you are in a movie theater. But there are also disadvantages. The first is that in many cases the receiver cannot determine the input codec. Sometimes the Dolby signal is received as stereo or vice versa, but this is only with the phone, with the computer everything is fine. The 2nd is the volume via Bluetooth. It is very quiet and there are no codecs for HiRes. And so, basically I did not notice any other disadvantages. I ordered Polk XT15 speakers for this receiver and I think that it will turn out to be an excellent audio system for this budget. The quality of the receiver itself is excellent, no complaints about it. It has enough power and the installation and setup are very simple, I figured it out the first time. I did not check the image quality, since my receiver is connected to a monitor, and I do not display an image from it. If anything, is it normal that when outputting from an iPhone, the sound is in Dolby Atmos format, the Dolby Surround mode is turned on on the receiver

great price at under $250 brand new. worked out of the box. full user manual (70 pages) available online from onkyo. suggest using 2.1 level HDMI cables to carry best hidef video and sound. multiple assignable sources. limited optical ports. great sound, great picture. also comes with automatice sound level balancing module with options to save time on setup. very impressed.

So far so good. Lots of input options and clean sound Runs my 5.2 home theater system.

It's an excellent entry-level receiver. The good: it's easy to set up, nice sound. Good, simple remote. Very useful info button displays input & output audio format. Other useful modes: quick adjust, vocal enhancement, night mode. 8K HDMI Video switching with no hiccups. Solid binding posts for all the speakers. (A rarity at this price point). Surprisingly attractive & hefty unit for the price. Overall, a terrific value for the money, provided one is not after an effective EQ & room correction tuning. Unbeatable amplification and processing at this price point—$250. (Sometimes it goes on sale for $200!!) The bad: It is not possible to adjust each channel's level individually post calibration, only the front speakers & the subwoofer. Otherwise, you are forced to run the calibration routine all over again. AccuEQ was ineffective for my dorm room, it kept choosing the wrong crossover frequencies. It consistently picked 70 Hz for the fronts/center/rear channels. These Klipsch speakers roll over -3db at 110 Hz and were not included in the pre-set cross-over modes available. I had to perform a 100% manual calibration on my Klipsch 5.1 Reference HT using an SPL meter + DVD Audio test tones (All channels frequency sweep 15–20 kHz, bass management 15Hz to 150 Hz) to dial in a proper blend between the subwoofer & the satellites. The Odyssey EQ calibration on Onkyo's past receivers was far superior.

I already owned 2 previous higher end Onkyo 7.2 surround receivers. The most recent one was an Onkyo TX-NR7100 9.2 Surround high power receiver that I bought to replace a fully functional 25 year old TX-DS787. I needed a newer model that supported HDMI, HDMI Arc, Bluetooth, and a host of other more modern features to connect the TV and run the main Surround system in the family room I took the DS787 into the Master bedroom to run the two stereo speakers. After about 3 weeks, the old Onkyo finally died, distorting everything regardless of input or output source at much reduced gain. So I started looking for simple stereo receivers at a low price range. What I found in the $200-$300 range were a bunch of stereo only, 2-channel receivers with limited digital input and outputs. So I expanded the search to 5.2 Surround models and found the Onkyo TX-SR3100 5.2-Channel AV Receiver. Although it had capabilities way beyond my present 2-speaker bedroom needs, I couldn't rationalize saving a few bucks and buying a Sony or Pioneer dedicated stereo receiver. The Onkyo TX-SR3100 5.2-Channel AV Receiver 80 Watt/channel at $250 has met my expectations for Onkyo based on the new TX-NR7100 9.2 that I also bought through Amazon for a little under $650, which I also found to exceed expectations. The TX-SR3100 has all the digital inputs and outputs (including an HDMI Arc/sArc for connection to and from the TV) and there is no longer any need for any analog inputs from the cable box, Media player or TV. It's all digital now. The on-screen display (OSDlets you easily customize all adjustable parameters on the receiver without having to use the one line display on the receiver itself. There is an OSD autosetup that I used once everything was connected that worked fine (but see below). It comes with a very easy to use remote that does everything. I have not touched the receiver itself since the final configuration I would say that the setup was easy, but that's a relative term. I needed to set up for OSD, Cable TV, several streaming channels and the media player to not interfere with each other. This also required a bit of fiddling with inputs on the xTX-SR3100 as well as on the new 43" Smart TV. The initial setup to just get the TV sound to play through the Onkyo probably only took 25 minutes to connect 2 speakers and 3 inputs, but it was probably 2 days of fiddling here and there for a few minutes at a time to get all the inputs and settings on the TX-SR3100 and the smart TV (Amazon 43" Insignia) just exactly perfect. Are there any cons to the TX-SR3100? Only when comparing it to the TX-NR7100 which cost nearly 3 times as much. In comparison, the TX-SR3100 has much more limited tone controls. The TX-NR7100 has a separate 9 band equalizer for each of the speakers, and I was expecting the same for the TX-SR3100. But it only has a system-wide bass and treble control from 0-10 dB boost. Just fine for the bedroom but might be limiting if you are at least an above average user using it to run a true 5.2 surround system. I couldn't be more pleased with the TX-SR3100. For the price, I think it is absolutely unbeatable. Below are a few screen shots from the back panel (from the download only) manual to aid you in your selection and probably setup if you buy this.

This is my third Onkyo AV receiver. I bought my first before the days of HDMI. The one that followed was replaced by this one only because I need HDMI 2.1 support. Reliability has been incredible over the years and I expect this one to be obsolete before it dies like its predecessors. Then of course, the quality of the amplifier and the other associated circuitry. The auto set up feature does a great job of setting speaker volumes appropriately. I’ve never used such a system, but they are generally found on receivers costing 2 to 3 times the price. While the wattage claims may be somewhat exaggerated, it has more than enough power for a typical large family room. I was able to score mine in a flash sale for $199. Even at $250 the price performance blows away pretty much everything out there. Grab one while you can.

After two months of use, my receiver stopped working and displayed the message "call customer service" which I tried to do on numerous occasions. I found that there is no customer service. Since the receiver malfunctioned after the 30-day return period, Amazon would not take it back or make an adjustment. Amazon tried calling the manufacturer on my behalf but had no success. Therefore, I am out the money I paid for the receiver (it was new, not refurbished) and stuck with a receiver that stopped working after 60-days. This is wrong and poor customer service by both Onkyo and Amazon. Since I cannot trust the manufacturer's warranty nor Amazon to correct this situation, I will not purchase these types of item from Amazon. Buyer be aware.

I had no issues with movies or games and the sound quality with anything wired. Receiver was very easy to plug and play. The deal breaker for me is the bluetooth connection. I constantly use my receiver's bluetooth abilities to play music when I'm cooking or cleaning. For some reason I can't get rid of the interference on this receiver. Everytime I hook up the bluetooth, whether it be through my phone or my computer, I get a loud background buzzing. This never happened with my old receiver, nor does it happen with any other bluetooth speakers I own. I haven't made any changes to other devices since replacing my old receiver. So I'm going to return it and try my luck with a different one.

Great

Se debe instalar vida usb el firmware para sacarle el mejor provecho, lo tengo con unas torres polk audio tx70 y pensaba acoplarle un sub woofer pero creo que no es necesario, con esas bocinas y la señal que manda el onkyo son suficientes bajos

5.1 canais, excelente.

Awesome player. Easy to set up. Sounds great. Works great with my Sony tv.

For the the price it totally worth it! The only downside it doesn't support WIFI or ethernet connection!
