Get tomorrow’s features today with original Dynamic Audio Amplification in the value-packed TX-NR555 Network A/V Receiver. This smart hub supports Dolby Atmos® and DTS:X enhanced with AccuReflex phase-calibration technology for crystal-clear object-based sound, and also includes the latest HDMI® spec for 4k video.
Backed by 70 years of experience building high-grade audio components, the TX-NR555 amplifies accurate, noise-free signal processing with high-current power for dynamic speaker control. The result is pure, rich and authentic sound.
Onkyo's dynamic audio amplification delivers massive power at 140 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven)/ 80 W/Ch (8 Ohms, 20 Hz-20 kHz, 0.08% THD, 2 Channels Driven).
Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the audio signal to its original form following processing. Unlike conventional filters, VLSC removes pulse noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity for a smooth analog signal.
The TX-NR555 Powered Zone 2 brings audio to speakers connected to the receiver into a second room. With the dedicated Zone 2 DAC, you can send internet audio sources to your second listening zone.
Dolby Atmos moves sound around you in three-dimensional space, so you feel like you're inside the action. The TX-NR555's Dolby Atmos decoding transports you from the ordinary into the extraordinary.
Sound designers and artists mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.
Additionally, the Dolby surround up-mixer processes content not mixed for Dolby Atmos to fill the flexible speaker layouts of a Dolby Atmos system.
DTS:X is an object-based surround sound technology that includes height channels for a fully-immersive listening experience. DTS:X provides listeners flexibility, immersion, and interactivity. You will be able to personalize your audio experience, for example, by turning up JUST the dialog within a mix. DTS:X allows you to customize to your room layout as well as control dialog and dynamic range.
*Available via firmware update.

No matter what you're listening to, it will sound powerfully full, clean and clear. A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).
AccuEQ conducts two measurements- one to set the level, the other to set the distance and crossover for ALL speakers, including the subwoofer. In the second round of measurements, your room’s sonic characteristics are evaluated. Using this information, AccuEQ is able to prevent standing waves from forming by adjusting frequency response.
Choose to include or bypass EQ measurement for front left and right speakers, and choose to automatically or manually set the EQ. Further, you can save your own manual EQ settings into three available presets.
The new AccuReflex technology aligns the phase of upfiring "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object-based soundtracks.
FlareConnect™ mirrors network audio, analog, Bluetooth and USB
sources connected to the TX-NR555 and allows distribution
to compatible speakers and components in other rooms.
Music selection, speaker grouping, and playback management
across the home are built into the Onkyo Controller app for iOS
YOUR Home. YOUR Music. NO Limits
Note: FlareConnect™ is enabled with a firmware update. Multi-room audio enabled by this technology requires an optional Onkyo wireless speaker. Onkyo cannot guarantee the compatibility of its A/V receivers with other devices featuring FlareConnect™. Sharing audio from external inputs depends on the model and is enabled via firmware update. Sampling rates of 44.1 kHz and 48 kHz are supported. Please consult the Onkyo website for further announcements regarding these technologies.
