Review: Excellent receiver for those who want to listen to Dolby Atmos on a budget and with high quality - 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
Review: Incredible performance for the price - 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 desertcart 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 (desertcart 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.

## Features

- DOLBY ATMOS HEIGHT VIRTUALIZER: When playing any Dolby format, engaging Dolby Atmos Height Virtualizer enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.
- DOLBY ATMOS AND DTS:X FOR STELLAR SOUND: Dolby Atmos and DTS:X formats allow engineers to map sound anywhere in 3D space, effects moving from speaker to speaker all around the room and wrapping your audience in the latest films and games. You can also enjoy your 3D speaker layout with classic titles.
- HDMI 2.1A WITH 8K: HDMI 2.1a supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, as well as Dynamic HDR formats. Combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action, HDMI 2.1a with 8K ensures your system is ready for the clearest and cleanest picture available both now and down the road.
- ACCUEQ ROOM CALIBRATION: Streamlines the initial setup of your home theater by ensuring your receiver and speakers are properly calibrated to the room they’re in. This technology compensates for differences in speaker size and distance to equalize response so you get exceptional audio playback no matter the space you’re in.
- BLUETOOTH: Whatever audio is playing on your phone, tablet, or PC app can be streamed to the receiver with Bluetooth wireless technology. Once the receiver has paired with and remembered your device, it will start playback automatically whenever it detects an incoming Bluetooth audio stream.
- ADVANCED MUSIC OPTIMIZER: o Our Advanced Music Optimizer DSP listening mode reconstructs data that can be lost when audio files are compressed, which can happen with WMA, AAC, and MP3 formats. This technology brings files back to their original lossless quality by creating new signals to restore the minor details left out during the compression process.
