Nine amplification channels, built-in Dirac Live room correction at no extra cost, and connectivity ready for 8K and 120 Hz gaming: the TX-NR7100 brings together in a single chassis features usually reserved for higher-end models. THX Select certified and compatible with object-based audio formats, this AV receiver lets you build a 5.1.4 or 7.1.2 system without external amplification.
An amplification section worthy of large systems
The TX-NR7100 houses nine amplification stages capable of delivering 100 W per channel into 8 ohms in hi-fi conditions, and up to 250 W peak into 3 ohms. This power reserve makes it easy to drive 5.2.4 setups with four in-ceiling speakers or height speakers, or 7.2.2 setups with rear surround speakers. THX Select certification, which requires thousands of tests throughout the processing chain, guarantees faithful reproduction of the source material in rooms up to around 55 m³.
Onkyo’s “Dynamic Audio Amplification” philosophy is reflected in the circuit architecture: TI PCM1690 32-bit DACs feed the main section (7.1 channels) with a dynamic range of 113 dB, while the proprietary VLSC (Vector Linear Shaping Circuitry) technology comes into play after conversion to smooth the signal and eliminate residual impulse noise. The bandwidth extends from 10 Hz to 100 kHz, putting the amp in an ideal position for playing high-resolution files up to 192 kHz / 24-bit and DSD 5.6 MHz.
Dirac Live and AccuEQ: two approaches to room correction
The TX-NR7100 stands out thanks to the native integration of Dirac Live in its full-band version, covering the entire spectrum from 20 Hz to 20 kHz. This Swedish technology analyzes the room’s acoustics from several listening positions and corrects both the frequency response and time alignment of the speakers. Calibration is carried out via the Onkyo Controller app on a smartphone or via the Dirac Live software on a computer for more fine-tuned adjustment, with the option to manually tweak target curves.
The in-house AccuEQ alternative remains available for those who prefer a quicker setup. This built-in system measures up to nine positions and applies automatic correction, often resulting in more pronounced bass. The two systems cannot be used simultaneously: you choose one during configuration. Comparative tests show that Dirac Live generally offers a more coherent soundstage and better three-dimensional imaging, while AccuEQ focuses on bass impact.
HDMI 2.1 and gaming: ready for current consoles
The video section is built around seven HDMI inputs, including one on the front, and two outputs. The first three rear inputs (1 to 3) support a 40 Gbps bandwidth, allowing 8K 60 Hz or 4K 120 Hz signals to pass through without compression. Inputs 4 to 6 are limited to 24 Gbps, sufficient for 4K/120 with DSC compression. The front input remains HDMI 2.0 and is limited to 4K/60.
All HDMI 2.1 gaming features are present: VRR (Variable Refresh Rate) synchronizes the display with the source frame rate to prevent stuttering, ALLM (Auto Low Latency Mode) automatically switches the TV to game mode, and QFT (Quick Frame Transport) reduces display latency. HDR support covers HDR10+, Dolby Vision, HDR10 and HLG. The main HDMI output includes eARC to retrieve uncompressed audio streams from TV apps, while the second output can feed a zone 2 in 4K/60.
Audio formats and listening modes
Native decoding includes Dolby Atmos and DTS:X for object-based soundtracks, with their respective upmixers (Dolby Surround and DTS Neural:X) to spatialize stereo or traditional 5.1 content. IMAX Enhanced certification ensures optimized handling of films mastered to this standard. The four THX modes (Cinema, Music, Games, Surround EX) apply specific processing validated by THX engineers.
For setups without height speakers, Dolby Atmos Height Virtualizer simulates a vertical dimension from a conventional system. Theater Dimensional mode, for its part, attempts to create a surround effect with only two or three front speakers. A partnership with Klipsch has also resulted in Klipsch Optimize mode, which automatically applies crossover settings tailored to the brand’s Reference and Reference Premiere speakers.
Comprehensive connectivity for varied sources
Beyond HDMI, the TX-NR7100 accommodates analog sources via six stereo RCA inputs and an MM phono input for turntables. Digital sources can use two optical and two coaxial inputs. Dual-band Wi‑Fi, Ethernet and aptX HD Bluetooth (transmit and receive) round out the connectivity options.
Network integration provides access to streaming services Spotify, Tidal, Deezer, TuneIn and Pandora directly from the receiver. AirPlay 2 compatibility lets you stream from Apple devices and integrate the amp into a multiroom system. Chromecast built-in and DTS Play-Fi further extend the options. “Works with Sonos” certification allows control via the Sonos app when the receiver is paired with a Sonos Port, with volume and input selection management.
Alexa and Google Assistant voice assistants are supported via compatible external devices. Three zones can operate simultaneously: the main zone, a zone 2 with audio and video, and a zone 3 limited to audio. The speaker terminals accept impedances from 4 to 16 ohms. Two subwoofer outputs are available, but they are treated as a single channel (no independent management).
Ergonomics and build
The TX-NR7100’s design follows the established NR series codes: a sober black front with a large green fluorescent display, three rotary knobs (volume, sound mode, tone), and a row of buttons for direct source selection. The removal of the flip-down panel found on older models frees up space and simplifies access to the front HDMI socket, the mini-jack audio input and the 6.35 mm headphone output.
Inside, the layout remains classic with the power transformer on the left and the amplification stages on the right, flanked by two filter capacitors. An internal fan may kick in under heavy load, but remains inaudible in most usage conditions. The metal chassis is lighter than on the higher-end RZ series models, and the speaker terminals use screw connectors instead of widely spaced banana posts.
The supplied remote control is compact, with white markings on a black background, but does not have backlighting. The Onkyo Controller smartphone app offers a more comfortable alternative for menu navigation and Dirac Live calibration. The on-screen menus (OSD) displayed on the TV are comprehensive and allow access to all settings.
A clearly assumed mid-range positioning
Within the Onkyo lineup, the TX-NR7100 sits at the top of the NR series, just below the RZ models with their more upmarket design and more robust construction. It shares much of its digital platform with the TX-RZ50, including the same TI Aureus and Cirrus Logic DSPs for audio processing. The difference lies in the finish, the power supply section, and the absence of full pre-outs for external amplification (available only for the main channels and subwoofers on the NR7100).
Pure Direct mode bypasses DSP processing for more direct listening, while ECO mode reduces power consumption. Bi-amping the front speakers is possible by reassiging the rear surround channels. Speaker distance settings are adjusted in 3 cm steps, a precision considered sufficient for most installations but less fine than the 1 cm increments offered by some competitors.
Does the included Dirac Live cover all frequencies or just the bass?
+
The Dirac Live license built into the TX-NR7100 is a full-band version, able to correct the spectrum from 20 Hz to 20 kHz. Some competing receivers only offer a version limited to low frequencies (usually up to 500 Hz) and charge extra for an upgrade. This full inclusion is a notable advantage at this price point.
Can the AccuEQ and Dirac Live calibration systems be used at the same time?
+
No, the two systems are mutually exclusive. Running calibration with one overwrites the settings of the other. You must choose between AccuEQ, integrated into the receiver menus and simpler to set up, or Dirac Live, which is more precise but requires the use of the mobile app or computer software.
Can the TX-NR7100 stream to multiple rooms simultaneously?
+
The receiver manages up to three zones: the main zone with all channels, a zone 2 with audio and video (up to 4K/60), and a zone 3 with audio only. Zones 2 and 3 can use reassigned surround channels or dedicated line outputs. With three Sonos Ports, each zone can play a different stream.
Do all HDMI inputs support 4K/120 Hz for gaming?
+
All rear HDMI inputs (1 to 6) accept 4K/120 Hz, but only inputs 1 to 3 offer 40 Gbps bandwidth for this mode without compression. Inputs 4 to 6 use DSC compression to achieve 4K/120. In practice, with current consoles like the Xbox Series X or PS5, all six inputs work at 4K/120 Hz.

So I replaced my old 5.1 Sony amp. With this excellent Onkyo amplifier, more than enough for a dedicated 22 m² room. The volume level is at 70; I like watching action movies at a fairly loud volume, so there’s still plenty of headroom. I also appreciate the complete calibration and Tidal support. I recommend this home cinema amplifier to anyone who doesn’t want to break the bank and still wants to benefit from the latest audio technologies.

J'ai donc remplacé mon ancien ampli Sony en 5.1.
Par cet excellent ampli Onkyo, largement suffisant pour une salle dédiée de 22m2. Le niveau de volume est à 70, j'aime bien voir les films d'actions avec un volume sonore assez fort il y a donc encore de la réserve. Ce que j'apprécie également c'est le calibrage complet avec Tidal.
Je conseille cet amplificateur HC à tout ceux qui n'ont pas envie de se ruiner et bénéficier des nouvelles technologies sonores.
