Onkyo TX-RZ50 – 9.2 Channel AV Receiver

11.2-Channel Processing
Supports up to 11.2-channel processing with pre-outs for 7.2.4 system layouts, enabling premium home theater setups with flexible speaker configurations.

Dirac Live® Room Correction
Dirac Live calibrates your system to your room’s acoustics, improving clarity, bass, and imaging across the full frequency spectrum (20 Hz–20 kHz). It uses either the included wired microphone or optional USB mic via smartphone, tablet, or PC/Mac application for precise, balanced measurements.

THX® Certified Select Theater-Reference Sound
Ensures the same reference volume and tonal balance as commercial cinemas in rooms with a screen-to-seat distance of ~12 ft (3.5 m). Certification requires passing more than 2,000 tests across 75 categories.

IMAX® Enhanced
Delivers master-quality IMAX content with immersive 3D object-based audio and optimized video processing, replicating the cinematic IMAX experience at home.

Dolby Atmos® and DTS:X® with Height Virtualizer
Immersive 3D audio maps sounds as perceived in real life, with up to 7.2.4 or 5.2.4 speaker layouts. Height Virtualizer creates virtual surround and height effects using standard speaker setups. Legacy content can be upmixed with Dolby Surround® and DTS® Neural:X for full 3D playback.

Supports 8K/60p, 4K/120p, Dynamic HDR formats (HDR10+, Dolby Vision™, HLG), VRR, ALLM, and QFT for low-latency, tear-free gameplay. eARC passes high-bitrate audio from TV to AVR for decoding and amplification.

SMART AV Receiver™ Multi-Room Streaming
Integrated support for Chromecast built-in, AirPlay 2, DTS Play-Fi®, and Works with Sonos allows seamless multi-room audio. Built-in access to Spotify, TIDAL, Deezer, TuneIn, Pandora, and Amazon Music HD.

Sonos Certified
Easily integrates with existing Sonos systems or starts a new multi-room setup. Supports up to three Sonos devices independently for different streaming sources and zones.

Voice Control Integration
Compatible with Google Assistant and Amazon Alexa for hands-free control of playback, volume, and input selection.

Bidirectional Bluetooth® Wireless Audio
Send or receive audio via Bluetooth. Stream from devices to the AVR or transmit from the AVR to wireless headphones using SBC, AAC, aptX™, or aptX HD codecs.

Multi-Zone Audio Flexibility
Dedicated Zone 2 and Zone 3 outputs, including DAC support, allow independent or synchronized audio playback in multiple rooms. Zone B line-out supports wireless headphone playback. HDMI and SPDIF inputs support PCM audio.

Optimized for Klipsch Speakers
Klipsch Optimize Mode automatically applies recommended crossover settings for select Klipsch Reference and Reference Premiere speakers.

Advanced Music Optimizer™
Enhances compressed audio to restore harmonics and improve clarity and fullness.

Vocal Enhancer
Boosts dialog intelligibility for movies, TV, and streamed content.

Exclusive Refinements for Clear Sound
Short HDMI signal paths, isolated SoC board, reinforced power-supply lines, and refined power-amp grounding reduce noise for clearer, more detailed audio.

Flexible Setup & Automation Integration
12 V trigger output and CEC allow automated control of external devices like projectors. Ethernet and RS-232 ports support integration into home automation systems. IR repeater input allows hiding the AVR from view.
