Custom Toroidal Transformer and Hi-Current Amps for Ultra-Low-Frequency Sound
Backed by 70 years’ experience building amplifiers and high-grade audio components, the TX-RZ900’s custom toroidal transformer and capacitors help to reproduce ultra-low frequencies down to 5 Hz so you can feel the bass impact in your chest. Our high-current amplification system also enables enhanced control of the speakers for accurate and dynamic sound.

Non-Phase-Shift Amp for Realistic Audio Imaging
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.

VLSC™ for Noiseless Audio Processing
Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the signal in its original form following processing. Unlike conventional filters, VLSC completely removes pulse-noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity.

Parallel Push-Pull Amplification with Three-Stage Inverted Darlington Circuitry
Parallel Push-Pull Amplification on the front channels enables high instantaneous current through low-impedance Three Stage Inverted Darlington Circuitry, delivering power, current, and efficiency that is simply unrivalled in its class.

DTS:X™ and Dolby Atmos® Support
DTS:X is a next-generation object-based surround-sound technology that includes height to deliver a fully immersive listening experience in your living room. DTS:X provides the ultimate in flexibility, immersion, and interactivity. Dolby Atmos transports you from an ordinary moment into an extraordinary experience with captivating, multidimensional sound that fills your room and flows all around you to move your mind, body, and soul.

THX®-Certified Amp Quality
THX certification guarantees the same high-volume, low-distortion sound you experience in a commercial cinema in your listening room. THX® Select2™ Plus is recommended for screen-to-seat viewing distances of 3-4 m.

Premium 384 kHz/32-bit DAC for Hi-Res Audio
Onkyo A/V receivers are engineered for universal Hi-Res playback including DSD 5.6 MHz and 192 kHz/24-bit FLAC files. A top-quality AK4458 DAC from Asahi Kasei extracts the best possible performance from any format for transparent, lifelike sound.

HDMI® 8 In / 2 Out Including 1 Front (4K UltraHD / HDCP 2.2 / 4:4:4 Color)
HDMI terminals support 4K/60 Hz video as well as HDCP 2.2 for next-generation UltraHD streaming and broadcasting.

Bluetooth Audio, Wi-Fi®, and AirPlay with Spotify
Stream virtually any audio to your home cinema with zero hassle. Available internet radio and music subscription services include Spotify and many more.
