The receiver offers a total of seven HDMI inputs and three outputs, all supporting eARC and ready for 8K/4K Ultra HD, which we found to be more than sufficient for connecting multiple devices, from gaming consoles to Blu-ray players and streaming devices. The inclusion of legacy connections like component and composite inputs was a pleasant nod to enthusiasts with vintage equipment. Additionally, the 13 preamp RCA connectors with two independent subwoofer outputs ensured flexibility for diverse audio setups.Onkyo TX-RZ70 front connections

Setting up the TX-RZ70 was remarkably intuitive. Plugging in the provided calibration microphone, we initiated the Dirac Live® Room Correction system. The process was streamlined, with the system intelligently recognizing the connected speakers and adjusting the audio output to optimize performance for the room’s acoustics. The on-screen interface, displayed on our test television, was easy to navigate, guiding us seamlessly through each step.

For us, from unboxing to complete setup, the experience with the TX-RZ70 was both smooth and gratifying.

Amplifier and Sound Performance

One of the main aspects we were eager to delve into was the TX-RZ70’s amplification capabilities. With a formidable 140W x 11 channels at 8 ohms, we anticipated a powerful sound delivery, and the unit did not disappoint. We began our testing phase with a demanding soundtrack, wanting to push the receiver’s Class AB amplifier to its limits. It was evident that Onkyo had engineered this device for resilience; even at higher volumes, the sound remained crisp, distortion-free, and dynamic. The layers of audio were distinctly discernible, with both the highs and the lows maintaining their clarity. The two independent subwoofer outputs enhanced the bass performance, resulting in a deep and resonant low-frequency response. We have selected the TX-RZ70 among the best 11.2 AV Receivers for 2023.

Transitioning to movie content, we activated the Dolby Atmos mode to evaluate its surround capabilities. The TX-RZ70 effortlessly recreated a cinematic atmosphere in our testing room, enveloping us in multi-dimensional sound that seemed to emanate from every direction. Dialogue remained clear and centered, while ambient sounds and soundtracks were presented with a spatial accuracy that truly immersed us in the on-screen narrative. It became evident that, beyond the technical specifications, the TX-RZ70’s genuine prowess lies in its ability to translate audio files into a real-life auditory experience, proving itself as an essential addition to any serious home theater setup.
