The all-new TX-RZ800 is designed for today's audiophile
Separate amp and processing blocks, custom high-current transformer, custom capacitors, Asahi Kasei 384 kHz/32-bit DAC, discrete low-impedance amp circuitry, and a 32-bit digital signal processor extract every drop of performance from DTS:X and Dolby Atmos soundtracks.

The high-current amp grips the speaker drivers
This amplification provides steady speaker control for effortlessly clear sound that extends down to 5 Hz without phase shifting, meaning you enjoy a perfectly focused audio image and earth-shaking bass. Combine this with original Vector Linear Shaping Circuitry (VLSC) technology,which cleanses the signal of pulse noise, and you have a receiver that just begs to be turned up to THX Reference levels, whether you're playing an object-based movie soundtrack over the latest spec HDMI terminals or an album

Ultra-Low Frequency Hi-Current Amp
Backed by 70 years experience building amplifiers and high-grade audio components, the TX-RZ800 reproduces ultra-low-frequencies down to 5 Hz so you can feel the bass impact in your chest. Our high-current amplification system also enhances control of the speakers for accurate and dynamic sound.

This delivers massive power at 185 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven) 135 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven).

Realistic Audio
Wide Range Amp Technology (WRAT) prevents phase shifting by pushing the roll-off point higher than the listening level frequency. Amplifying sound without phase shift creates an uncommonly clear, well focused, and realistic audio image.

Smooth Analog Signal
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.

THX-Certified Audio Quality
At the cinema, you practically feel the sound of the movie you're watching. With your own Onkyo THX certified receiver, you get that same thrilling tactile sound in your own home. THX certification guarantees the same high volume, low distortion sound you experience in a commercial theater in your listening room.

The TX-RZ800 meets the most demanding & rigorous performance certification: it has to pass 75 test categories, 2,000 tests, covering 14,000 data points. THX Select2 Plus is recommended for screen-to-seat viewing distances of 10-12 feet.

DTS:X Compatible
DTS:X is a next-generation object-based surround sound technology that includes height to deliver a fully-immersive listening experience. DTS:X provides listeners the ultimate in flexibility, immersion, and interactivity. Unlike channel-based audio, you will be able to personalize your audio experience.

For example, you can turn 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.

Supports Dolby Atmos
With Dolby Atmos, sound comes alive from all directions, including overhead. The format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the room, creating a breathtakingly realistic and captivating sonic atmosphere.
Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.

Additionally, a new Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system.

Ready for Ultra HD
The latest HDMI specification and HDCP 2.2 compatibility support the latest formats and technologies planned for Hollywood content. This latest HDMI spec offers a significant increase in bandwidth (up to 18Gbps) to support new features such as 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution, and 4:4:4 color space.
This Onkyo AVR enables transmission of High Dynamic Range (HDR) formats, and provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image.

Multi-Zone Audio & Video
The TX-RZ800 features Powered Zone 2 and Zone 2/3 Pre/Line-Outs for distributed audio playback, including Zone 2 digital audio and network audio output. Control the audio content in the zones via remote app; play the same song in all zones using Whole House Mode; or enjoy a different song in each room.

Further, there is Zone 2 HDMI output for HD video in a second Room, with Zone 2 HDMI supported on inputs 1, 2, 3, 4 & 5. Use the HDMI Sub Out to connect a second display in another room. This allows you to route 1080p content from the media players connected to your receiver and play it back on another TV with easy smartphone control.

Wireless and Network Streaming
The TX-RZ800 has AirPlay, Wi-Fi and Bluetooth technologies built in. 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. Or pair up and enjoy whatever's playing on your Bluetooth-compatible device for huge cinematic sound.
