THX-Certified for Theater Reference Sound

THX certification guarantees the same high volume and low distortion levels you experience in a commercial theater right in your listening room. THX Select2 is recommended for screen-to-seat viewing distances of 10-12 feet. To achieve THX certification, amplifiers must undergo a barrage of the industry’s toughest independent bench testing to satisfy THX requirements.

Your Speakers Will Thank You

Good speakers can be demanding and difficult to drive correctly, and most amps out there can’t do it. The TX-RZ3100’s amps deliver high instantaneous current to grip and control speakers, moving them through their entire range. It’s a significant boost to the dynamism, detail, and accuracy of music and movie soundtracks for a thrilling listening experience.

High-Current Digital Amplification Power Meets Control

The TX-RZ3100 combines high-current architecture with sophisticated digital amplification and filtering technology. Noise-reduction hardware and a custom high-output transformer delivers fast dynamics, thrilling power, and stunningly precise detail resolution. The result is velvet-smooth and emotionally evocative audio reproduction.

Noiseless Audio Processing

Vector Linear Shaping Circuitry (VLSC) virtually removes digital pulse noise for a smooth analog signal across all channels. Data is converted between sampling points, and these points are joined with analog vectors in real time to produce a smooth output wave form. The result is a virtually noiseless, smooth, analog signal based on the digital source, bringing out even the most subtle of nuances in audio sources.

Dolby Atmos

With 11.2 channels of instantaneous power, the TX-RZ3100 enables the current maximum Dolby Atmos and DTS:X home-theater layout of 7.2.4 channels in a self-contained component for the ultimate in multidimensional object-based surround sound.

FireConnect Multi-Room Audio

A firmware update enables almost any audio source connected to the receiver – from vinyl to streaming audio – to be sent wirelessly via FireConnect, powered by Blackfire, to an optional speaker placed anywhere in your home. Stable, fast, and easy to control with a mobile, it’s the smart way to set audio free.

Cohesive Multidimensional Sound

AccuReflex, part of the AccuEQ room calibration suite, phase-matches height and floor-standing speakers for transparent and seamless reproduction of object-based sound. AccuEQ optimizes the entire system to suit your space without affecting front-speaker characteristics for pure stereo listening.

Limitless Performance; Installation Friendly.

From multi-zone audio and video options, to dedicated RZ Series phone support and a three-year product warranty, the Onkyo RZ Series delivers superior audio performance in the configurations you want with the support you should expect from the leader in home audio.
