It supports 4K and 8K formats, offering a range of advanced features usually reserved for higher-end models. This combination of user-friendliness and performance makes it an outstanding value for money.
The TX-SR3100 supports Dolby Atmos and DTS:X, creating a three-dimensional sound field where audio can move in all directions, including overhead. This capability ensures an immersive listening experience that faithfully reproduces the intentions of sound engineers and content creators. The inclusion of Dolby Atmos Height Virtualizer further enhances this experience by creating virtual surround and height effects, even without additional speakers.
With HDMI 2.1a support, the TX-SR3100 is future-ready, capable of handling a wide range of video resolutions and refresh rates, including 8K60 and 4K120.

The receiver also integrates Dolby Vision and HDR10+ technologies, enhancing visual quality with sharp, clear images and vibrant colors.
AccuEQ room calibration technology streamlines setup by automatically calibrating the receiver and speakers based on room acoustics, compensating for differences in speaker size and distance. This feature ensures optimal audio playback across different environments.
The Vocal Enhancer technology brings dialogs and voices to the forefront by adding the center channel element to the front left and right speakers, ensuring clear speech even during action scenes or quiet moments.
For music lovers, the TX-SR3100’s DSP Music Optimizer listening mode restores compressed audio files to their original lossless quality by reconstructing data lost during compression. This is particularly beneficial for formats such as WMA, AAC, and MP3, allowing users to fully experience the depth and richness of their music collection.
The Onkyo TX-SR3100 sports a sleek, modern design that should complement any home theater setup. It offers versatile connectivity options, including HDMI 2.1 inputs for 8K and 4K resolutions and built-in Bluetooth 5.0, meeting a wide range of modern connectivity needs.
