However, if you are an American with a disability we are here to help you. Please call our disability services phone line at 920-459-2480 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves.

Dynamic Audio Amplification

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).

Image Feature

Smooth Analog Signal

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.

Image Feature

Multi-Zone Audio

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.

Image Feature

Supports Dolby Atmos ® up to 5.1.2 Channels

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.

Image Feature

DTS:X ™ Ready

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.

Image Feature

Music Made Easy with Chromecast built-in

Stream any music from your smartphone, laptop, or PC to the TX-NR555 with ease. Control playback with Chromecast enabled apps you know and love from your iPhone, iPad, Android™ phone or tablet, Mac® or Windows® laptop, or Chromebook™. Available via firmware update.

Image Feature

Supports HDR10, Dolby Vision ™ , BT.2020, 4K/60 Hz, and HDCP 2.2

SIX rear HDMI® inputs (HDMI 1-7), Main Out, and Sub Out support pass-through of HDR10, Log-Gamma), and Dolby Vision; the BT.2020 4K color standard; 4K/60 Hz video playback; and HDCP 2.2 for premium video content. Front HDMI terminal is ideal for temporary device connections. Dolby Vision is supported through inputs 1-3 and is available via firmware update.

Image Feature

Bluetooth / Wi-Fi ® with Pandora, Spotify, and AirPlay

The TX-NR555 has AirPlay, Wi-Fi and Bluetooth technologies built in. Stream virtually any audio from a smartphone, tablet or PC to your home theater for powerful sound. With Spotify, Pandora, and TuneIn built-in, as well as Deezer and Tidal (via firmware update available now), you can select a station and search for music available on these services via the Onkyo Controller app on your phone. The free Onkyo Remote app puts a range of streaming options at your fingertips, from universal hi-res audio via network-attached devices to internet streaming services to music on your smartphone and tablet.

Image Feature

384 kHz/32-bit Hi-Grade DAC

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).

Image Feature

AccuEQ & AccuReflex

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.

Image Feature

FlareConnect ™ Wireless Multi-Room Audio

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 and Android™.
