A Stellar Combination for Wraparound Sound

Dolby Atmos® and DTS:X® technologies enable engineers to position sound anywhere within a 3D soundscape, creating the effect of audio moving seamlessly from one speaker to another. This immersive mapping surrounds the audience with sound from every direction, enhancing the experience of both modern blockbusters and timeless classics.

Smooth Sharp Action

HDMI 2.1a enables support for higher video resolutions and refresh rates such as 8K60 and 4K120, along with Dynamic HDR formats. The 60Hz refresh rate delivers smooth and crisp playback of fast-moving scenes, while HDMI 2.1a with 8K capability ensures your system is prepared for the clearest, most detailed picture both today and into the future.

Clarity and Color Like You've Never Seen

See on-screen images with greater clarity and richer color. Dolby Vision and HDR10+ technology enhance your favorite content, delivering sharp visuals and vibrant, dynamic colors so you can sit back and enjoy the latest entertainment from the comfort of your couch.

Perfect Positioning Without Effort

AccuEQ Room Calibration simplifies the setup of your home theater by properly aligning your receiver and speakers to the acoustics of your room. It adjusts for differences in speaker size and distance, balancing the response so that you experience clear, consistent audio performance in any space.

Hear Every Whisper

The TX-SR3100’s Vocal Enhancer technology is designed to make dialogue and vocals stand out more clearly. By blending the Center channel information into the Front Left and Right speakers, it enhances speech intelligibility so conversations are easier to follow. Whether in loud action sequences with heavy effects or in subtle, quiet moments, you’ll hear voices with greater clarity at any volume level.

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, enabling Dolby Atmos Height Virtualizer creates a more immersive audio environment by simulating surround and height effects from standard speaker setups without additional height or surround speakers. The result is a convincing three-dimensional listening experience that feels natural and expansive. Sounds that should be coming from above you or far away will feel like they really are.

Additional Features

With Klipsch Optimize Mode, you can seamlessly integrate Klipsch Reference and Reference Premiere speakers with your Onkyo AV receiver. All you need to do is select the specific speaker model assigned to each channel, and the receiver will automatically apply the optimized crossover settings. This ensures that your speakers and receiver are perfectly matched for accurate, high-quality sound performance.

8K/4K Ultra HD provides an incredibly immersive viewing experience by offering double the horizontal and vertical resolution of 4K. With four times as many pixels, images appear sharper, more detailed, and lifelike, making movies, games, and shows more engaging than ever.

Any audio playing on your phone, tablet, or PC app can be streamed directly to the receiver using Bluetooth wireless technology. Once paired and remembered, your device will automatically trigger playback whenever the receiver detects an incoming Bluetooth audio stream.
