Description:

  • 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.

  • The TX-SR3100 powers epic movie nights, much-needed binge sessions, gaming marathons, and more with the most immersive and sought-after AV tech of the day. Elevate your home entertainment system with this user-friendly, feature-packed AVR.

    5.0 out of 5 stars Excellent receiver for those who want to listen to Dolby Atmos on a budget and with high quality

    M. · February 15, 2025

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } The media could not be loaded. 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

    5.0 out of 5 stars OMG what a perfect product for a five channel setup with multiple HDMI sources

    P.D. · March 2, 2025

    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.

    I have owned this brand of receivers before, and they have always lasted the test of time so it was in a no-brainer when it came time to upgrade to purchase another one. The receiver does everything that states it will do swimmingly although I’ve only had it for a week so far so good. One of the best features I like about this receiver is the audio calibration set up and may put this thing together easy. The receiver captured all the right frequencies from subwoofers to the tiniest of my speakers so there was not much for me to do but sit back and enjoy for those of you looking for something extremely simple but with updated features go with this sit back and enjoy your new sound stage. Also the biggest reason for me purchasing the receiver was the fact there is an audio option for increase Voice enhancement. This was a huge plus and a huge deciding factor on purging this receiver.

    4.0 out of 5 stars Excellent entry level receiver, with some caveats one should be aware of.

    L.R. · March 15, 2025

    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.

    5.0 out of 5 stars POWERFUL!

    Onkyo X Denon

Qual não foi minha surpresa, um tanto negativa, ao perceber que o som não era, digamos, impactante como o do Onkyo. Fiz então uma comparação real entre os dois, colocando um trecho de um filme de ação, com direito a explosões, perseguições de carro, e demais ingredientes. E se confirmou a minha primeira impressão. O Denon S760 parecia não ter "pressão sonora", apesar do som muito limpo. Mas tudo é uma questão de gosto pessoal. Devolvi então o Denon e adquiri este Onkyo SR3100. Fiz o mesmo teste e confirmei as suspeitas. O Onkyo SR3100, mesmo com dois canais a menos (Sem caixas Dolby Atmos) me agradeou muito mais. Portanto, se você procura um receiver com essas características, este modelo Onkyo atende perfeitamente. Se puder investir em caixas de som de qualidade, como JBL, melhor ainda.

    Muy buen amplificador 5.2, 80W

    F.B. · April 11, 2025

    Llego a tiempo y con empaque sin problema. Amplificador 5.2, 80W excelente, recibe 4 entradas en HDMI (4K) y una salida, 2 en señal audio digital (una optica y otra coaxial) y 3 entradas audio analógico. Receptor AM/FM y receptor Bluetooth. Maneja Dolby Atmos, Dolby Vision, DTS-X. Realiza calibración del sitio de escucha mediante AccuEQ. Si no requiere THX o 7.2 o conexión a red datos, este equipo cumple. Le quito una estrella porque el micrófono incluido para calibración no sirvió y tuve que usar uno de un amplificador Onkyo anterior, lo demas excelente.
