A Stellar Combination for Wrap-Around 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

Onkyo's 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.
