The all-new 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

Features:

A stellar combination for wraparound sound
Dolby Atmos and DTS:X formats allow engineers to map sound anywhere in 3D space, meaning effects can move from speaker to speaker all around the room to wrap your audience in the latest films and games or with your favorite classic titles.

Smooth, sharp action
HDMI 2.1a supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, as well as Dynamic HDR formats. Combined, 60Hz refresh rate enable smooth and sharp viewing of high-speed action, and HDMI 2.1a with 8K ensures your system is ready for the clearest and cleanest picture available both now and down the road.

Clarity and color like you've never seen
See images on-screen with new clarity and vivid color. Dolby Vision and HDR10+ technology will level-up your favorite content so you can relax and enjoy the newest content with crisp, clear visuals and dynamic colors, all from the comfort of your couch.

Perfect positioning without the effort
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.

Hear every whisper
Emphasize dialogue and vocals with the TX-SR3100's Vocal Enhancer technology. By adding the Center element to your Front Left and Front Right speakers, it allows you to more clearly pick up on conversations during action scenes with loud explosions or quiet moments in heady dramas---no matter what where the volume is set.

Hear the musical nuance
Our 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 audio files back to their original lossless quality by creating new signals to restore minor details left out during the compression process.

Virtually immersive
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. Sounds that should be coming from up high and far off will sound like they really are.

8K/4K Ultra HD
8K/4K Ultra HD delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels.

Rated 5 out of 5 by from Fits the Bill, Good Price I bought this to replace a 20+ year old Yamaha receiver to gain Dolby Atmos support and fix an annoying audio sync problem I had caused a conflict between my TV audio settings and Apple TV settings. This unit is used for a home theater setup. I am pleased with this receiver. Pros: the automatic level setup that uses the included microphones, being able to select the exact speaker models that are connected to the unit. Cons: (minor) the volume button location on the remote is awkwardly toward the bottom (not where my thumb rests), only one set of outputs for main left and right speakers

Rated 5 out of 5 by from Only tx-nr3100 I bought this a month ago glad I did. I love the surround sound performance of TX-nr3100 I only use it for movie nights on Saturdays, the only thing is how many watts I'm getting into 4 ohms load per channel.

Rated 5 out of 5 by from Clean, Crisp and Earthshaking I love this receiver. The 4K upgrade is awesome. I have an entire Klipsch 5.1 system with 2 subs. The entire room shakes. Get you one.
