Onkyo TX-RZ70

Onkyo TX-RZ70 – High-End Home Theater Without Compromise

With the TX-RZ70, Onkyo makes a clear statement in the premium AV receiver segment. This model is consistently designed for performance – both in signal processing and amplifier architecture.

The massive chassis construction not only contributes to the feel but also specifically reduces mechanical resonances that could negatively affect signal purity. Inside, a cleanly structured layout with separate signal paths and generously dimensioned power supply is apparent.

The result is a receiver that effortlessly controls even complex setups and remains sonically stable.

Discrete 11.2-Channel Power Amplifiers – Control Even at High Levels

The TX-RZ70 relies on fully discrete power amplifiers for all eleven channels. This architecture allows for more precise control of the loudspeakers and prevents the sonic limitations that can occur with integrated amplifier solutions.

With up to 140 watts per channel (8 ohms, 20 Hz – 20 kHz, 0.08% THD, 2 channels driven), ample power reserves are available to confidently drive even demanding loudspeakers.

In practice, this means:

• clean dynamics even at high volumes
• stable control in the bass range
• precise spatial staging

Especially with 7.2.4 setups, the TX-RZ70's ability to differentiate complex sound information is evident.

Dirac Live Full Bandwidth – Precision in Time and Frequency Domain

A central feature of the TX-RZ70 is the integrated Dirac Live room correction in the Full Bandwidth version.

Unlike classic calibration systems, Dirac analyzes not only the frequency response but also the impulse response of the loudspeakers in the room. This corrects temporal delays, leading to significantly better coherence.

The result:

• more precise localization of effects
• clearly defined soundstage
• significantly more homogeneous reproduction

Optionally, the system can be expanded with Dirac Live Bass Control, which makes the low-frequency range even more controlled and uniform.

THX Certified Ultra – Cinema Reference in the Living Room

The THX Ultra certification ensures that the TX-RZ70 achieves consistent, cinema-quality reproduction even in larger rooms (up to approx. 85 m³).

This not only checks power reserves but also parameters such as:

• frequency linearity
• dynamic behavior
• distortion-free reproduction

For the user, this means reproduction that clearly adheres to professional cinema standards.

HDMI 2.1 – Full Support for 8K and High-Frame-Rate

The TX-RZ70 is fully HDMI 2.1 compatible and supports:

• 8K/60 Hz
• 4K/120 Hz
• HDR10, HDR10+, Dolby Vision, HLG

In addition, modern gaming features are supported:

• VRR (Variable Refresh Rate)
• ALLM (Auto Low Latency Mode)
• QFT (Quick Frame Transport)

This means the receiver is designed not only for movies but also for high-end gaming.

Extensive Audio Formats – Immersive 3D Audio

The TX-RZ70 supports all relevant 3D audio formats:

• Dolby Atmos
• DTS:X
• IMAX Enhanced

This allows complex sound designs to be reproduced precisely – from subtle spatial details to large-scale effects.

Streaming & Network – Modern Integration

In terms of streaming, the TX-RZ70 is also fully equipped for current requirements:

• AirPlay 2
• Chromecast built-in
• Spotify Connect
• TIDAL, Deezer (depending on region)
• Roon Tested

Additionally, integration into multi-room systems is possible, allowing music to be played synchronously throughout the house.

Pre-Outs & System Integration – Maximum Flexibility

A decisive advantage of the TX-RZ70 is its complete 11.2-Pre-Out section. This allows the receiver to be expanded into a separate pre/power amplifier system at any time.

This enables:

• use of external high-end power amplifiers
• targeted upgrading of individual channels
• long-term scalability of the system

Especially for ambitious users, this is a clear plus.
