    Dynamic Audio Amplification: The TX-NR555 AV receiver features Onkyo's Dynamic Audio Amplification with a 7-channel amplifier rated at 80 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). Onkyo's new Dynamic Audio Amplification technology incorporates a Hi-Current amplifier design, WRAT (Wide Range Amp Technology), H.C.P.S (High Current Power Supply), and Optimum Gain Volume Circuitry for dynamic, detailed, and clear sound.

    • Hi-Current Amp Design: The unique elements of Onkyo's Dynamic Audio Amplification system comprise high-current, low-impedance architecture to accurately and precisely control large speaker cones while enabling instantaneous response to dynamic changes for authentic audio reproduction.
    • Wide Range Amp Technology (WRAT): Onkyo's Wide Range Amp Technology (WRAT) circuit layout prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image.
    • H.C.P.S. (High Current Power Supply): Under the anti-resonant cover of any Onkyo receiver, you'll instantly notice the High Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power supply design and high-capacity filter capacitors, it delivers the large amounts of power necessary for reproducing the wide dynamics of movie soundtracks and the detail and clarity of your music.
    • Optimum Gain Volume Circuitry: Optimum Gain Volume Circuitry adjusts the gain so that less than half the amount of attenuation is needed, ensuring the signal never comes close to the noise floor. This protects the signal against noise, resulting in a dramatically clearer sound.

    Amplifier Assignment: The 7-channel amplifier can be configured in a variety of ways to match your type of speaker setup.

    • Surround Back (7.1ch): The Onkyo TX-NR555 provides 7.1ch surround in your main listening area with dedicated Surround Back speakers.
    • Front Bi-Amp (5.1ch): The Surround-Back/Height speaker terminals can be reassigned and used along with the Front terminals to bi-amp the front speakers, providing improved bass & treble performance. When bi-amping the front speakers the receiver is limited to a 5.1ch speaker system in the main room (no Surround Back or Front Height speakers)
    • Powered Zone 2 (7.1ch + Zone 2): In this configuration, you can connect Front, Center, Surround, Surround Back, and Zone 2 speakers to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back (or front height) channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power.
    • Dolby Atmos (5.1.2ch): The Surround-Back/Front-High speaker terminals are assigned to power a pair of Front-Height, Overhead Ceiling, or Dolby Atmos-enabled speakers to create 5.1.2ch Dolby Atmos surround sound. Zone 2 speaker can still be powered by the receiver in the configuration. When Zone 2 is off, all seven channels will be used in the Main Zone for Dolby Atmos. However, when Zone 2 is on, power to the Dolby Atmos channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power without Dolby Atmos.

    Advanced 32-Bit DSP Engine: The Onkyo TX-NR555 AV receiver employs a powerful and highly accurate 32-bit DSP (Digital Signal Processor) engine for better surround sound reproduction.

    384kHz/32-Bit Hi-Grade DAC: The Onkyo TX-NR555 utilizes one premium-quality AK4458 digital-to-analog converter from Asahi Kasei for all channels. This 384kHz/32-bit DAC 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, WMA Lossless, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD). The TX-NR555 offers additional DAC signal processing to make sure your movie & music soundtracks sound their best.

    • Vector Linear Shaping Circuitry (Front Channels Only): Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the signal in 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 signal's data is converted between sampling points and joined with analog vectors in real time to produce a smooth output wave form. The result is a virtually noiseless, smooth, analog signal that brings out even the most subtle of nuances in music sources.
    • PLL Jitter-Cleaning Circuit Technology: PLL (Phase Locked Loop) jitter-cleaning circuit technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves audio quality. Jitter-cleaning technology works both for digital signals input via HDMI and for digital signals converted from analog signals inside the receiver itself

    AccuEQ w/ AccuReflex: AccuEQ conducts two measurements: (1) it measures and sets the distance, sound pressure level and crossover of your speakers and subwoofer to ensure all channels are treated equally (2) it evaluates your room's sonic characteristics and adjusts your speaker's frequency response to prevent standing waves from forming. AccuEQ incorporates AccuReflex technology to align 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. You can save up to 3 AccuEQ presets. The included microphone plugs into the front-panel of the receiver.

    Note: You can choose bypass the AccuEQ for your front speakers or all speakers, and manually set the distance, crossover, EQ, and level of each speaker.

    Compatible Digital Audio Formats: The AV receiver supports the following stereo & multichannel digital audio formats through its HDMI jacks and optical/coax digital inputs.

    Digital Audio Connector Audio Signal Type Audio Signal Format
    HDMI 2Ch Linear PCM 2ch, 32-192kHz, 16/20/24-bit
    Multichannel Linear PCM 8ch, 32-192kHz, 16/20/24-bit
    DSD 2ch, 2.8 MHz, 1-bit

    Multichannel Linear PCM 6ch, 32-96Hz, 16/20/24-bit
    Bitstream Dolby Digital, DTS, DTS ES,DTS 96/24

    Immersive Surround Sound: The Onkyo TX-NR555 AV receiver goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos, & DTS:X.

    • Dolby Atmos: With Dolby Atmos, sound comes alive from all directions, including overhead, to fill your home theater with astonishing clarity, power, detail, and depth. The TX-NR555 has the processing power to run a more enveloping 5.1.2ch Dolby Atmos layout utilizing ceiling mounted or Dolby Atmos-enabled speakers (sold separately). A 5.1.2ch speaker configuration is based upon a traditional 5.1 speaker layout complemented by 2 overhead or Dolby Atmos-enabled speakers.
    • DTS:X (via future firmware update): DTS:X will be enabled through an online firmware update coming later this year. DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.

    Post Decoding Formats: The Onkyo AV receiver supports Dolby Surround, DTS Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and multichannel decoding formats.

    • Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
    • DTS Neural:X (via future firmware update): DTS Neural:X will be enabled through an online firmware update coming later this year. DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
    • DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that takes any two-channel source (including television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience.

    Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital & DTS processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:

    • Orchestra: For classical or operatic music.
    • Unplugged: For acoustic instruments, vocals, and jazz.
    • Studio-Mix: Suitable for rock or pop.
    • TV Logic: Adds realistic acoustics to TV shows.
    • Game: The receiver offers four different Gaming modes - RPG, Action, Rock, and Sports.
    • All Ch Stereo: Stereo sound from all speakers. Ideal for background music.
    • Full Mono: All speakers output the same sound in mono.
    • Theater-Dimensional (T-D): Theater-Dimensional circuitry takes the complexity out of conventional surround-sound setups and lets you experience the excitement of surround sound from as few as two ordinary speakers. Theater-Dimensional's unique multi-speaker modes let you place up to five speakers conveniently by the TV, for the most realistic virtual-surround sound possible.

    Direct Mode: In Direct mode, audio from the input source is output without surround-sound processing. This mode delivers pure sound with minimum sound quality adjustment and filtration.

    Audio Enhancements: The Onkyo TX-NR555 receiver provides various audio enhancements to deliver a high-quality listening experience every time.

    • CinemaFilter: The CinemaFilter softens overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
    • Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz, analog input signals, and Bluetooth audio.
    • Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.

    Bass Management: The Onkyo AV receiver offers Tone Control, Phase Matching Bass technology, and a Double Bass feature to get the most bass impact out of your system.

    • Tone Controls: You can independently adjust the Bass (90Hz) and Treble (7.5kHz) of the receiver's Front L/R channels from -10 to +10 dB.
    • Phase Matching Bass: Onkyo's Phase-Matching Bass optimizes low frequencies while preserving mid-range clarity. This means that powerful bass plays back with clear vocals; it doesn't overpower them.
    • Double Bass: You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer.

    Volume Setup: The Onkyo AV receiver provides the following volume settings.

    • IntelliVolume: With IntelliVolume, you can set the input level for each input (+/-12dB) selector individually. This is useful if one of your source components is louder or quieter than the others. This function does not work in Zone 2.
    • Maximum Volume: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 30-79 (max), or Off (disabled).
    • Power On Volume: Use this feature to set the volume level when the power is turned on. You can choose between Last (same as the volume when the unit was turned off), Min (0), or 1-79.
    • Mute Level: Set the volume lowered from the listening volume when "Mute" is selected. Choose from 0, -40dB, or -20 dB.
    • Headphone Level: With this setting, you can specify the headphone volume (+/-12dB) relative to the main volume. This is useful if there's a volume difference between your speakers and your headphones.

    Phono Input: The Onkyo AV receiver is fitted with a Phono (MM) input and ground terminal for connection of a turntable, so you can enjoy listening to your vinyl records.

    Front-Panel Aux Input: The TX-NR555 is fitted with a front-panel 3.5mm Aux input for connecting a portable audio player.

    Analog Audio Outputs: The Onkyo TX-NR555 is outfitted with the following analog audio outputs.

    • Binding-Post Speaker Terminals: There are binding-post terminals for all speaker connections - Front, Center, Surround, Surround Back/Height, and Zone 2. The binding post terminals will accept bare-wire, pin-connectors, and banana plugs (single only). Use 6- to 16-ohm speakers.
    • Dual Subwoofer Outputs: The receiver is fitted with two subwoofer outputs to connect dual powered subs for extra bass. The dual outputs are wired in parallel and share the same input signal (the are not discrete).
    • Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.
    Video Features

    HDMI 2.0a: The Onkyo TX-NR555 has six HDMI 2.0a inputs and one HDMI 2.0a output. Thanks to the latest HDMI 2.0a specification, the receiver can support 4K/60 Hz Ultra-HD video, HDCP 2.2 compatibility, 4:4:4 color sub-sampling, High Dynamic Range (HDR), and BT.2020 Wide Color Gamut.

    • 4K/60Hz: The TX-NR555 supports up to 4K (3840x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI
    • HDCP 2.2: The receivers HDMI 1-3 inputs and HDMI monitor output support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
    • 4:4:4 Color Subsampling: The receiver's HDMI 1-3 inputs and HDMI monitor output support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail. HDMI inputs 4-6 only support 4K 60/50Hz @ YCbCr 4:2:0.
    • HDR (High Dynamic Range): HDR provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth.
    • Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
