Details Review


The Onkyo TX-RZ840 is seriously impressive with its sleek and minimalist design. It's the perfect addition to any home entertainment setup. The front panel is super clean and not at all cluttered, giving off a really elegant vibe. And the display is pretty user-friendly, showing you all the important stuff in a quick glance. The well-made metal body not only looks good but also shows that the receiver is built to last. The buttons are positioned just right, so you can effortlessly reach all your favourite features. Plus, the display is super bright so you can easily see it even in those low-light situations.

I really dig the front-panel HDMI and USB ports. They make it super easy to hook up my phone or gaming console whenever I want. This cool little feature saves you the trouble of having to reach around to the back of your gear when you want to set things up in a jiffy.


The Onkyo TX-RZ840 9.2 Channel Receiver is really impressive because it has so many ways you can connect to it. This device has multiple HDMI inputs and outputs, so it can easily connect to a variety of devices like gaming consoles, Blu-ray players, and streaming devices. This is a great option for anyone looking to create a complete home entertainment system.

By the way, just so you know, not all HDMI inputs can handle 4K resolution. If you have multiple 4K devices, it might be a bit of a hassle to decide which ones to connect to the limited 4K-capable inputs. You should definitely check the specifications to make sure everything works smoothly with your 4K sources.

However, the receiver does have other connectivity options to make up for this limitation. With built-in Wi-Fi and Bluetooth, you can easily stream content from your compatible devices. This means you don't have to rely only on HDMI connections to access your favorite media.


The Onkyo TX-RZ840 is a real star when it comes to performance. It delivers such incredible, immersive sound that you'll be blown away. The audio experience is truly remarkable for its 9.2 channels, especially when you pair it with high-quality speakers. The receiver is amazing at handling all frequencies, from soft whispers to thundering explosions. It creates a captivating cinematic experience that really pulls you into the heart of the action.

The THX certification really takes the audio quality to the next level, making sure you catch every little nuance and detail in your favorite films, music, and games. You know, whether it's the gentle rustling of leaves or the energetic roar of a sports crowd, the sound always manages to captivate you, no matter how loud or soft it is.

Just so you know, if you use it for a long time, the receiver might get a little warm. Proper ventilation is super important to keep things running smoothly! To prevent any potential overheating issues, just make sure there's enough space around it and let the air flow freely. 

Where and When to Use

This receiver is wonderful for any home theater or media room setup. I thought it was really cool for watching films, sports events and gaming sessions. It's perfect for action-packed movies and thrilling video games because it can handle complex soundtracks and deliver deep bass. But if you have a smaller living space or a limited budget, this might be a bit too much.

Compatible Devices

I tried out the Onkyo TX-RZ840 with different devices like my 4K TV, PlayStation, and even a turntable. It handled all those devices flawlessly, making it super easy to switch between them and set them up. The AccuEQ room tuning system helped optimize the sound for my room's acoustics, which further improved the performance.

Ease of Use

Setting up the receiver was really easy because of the user-friendly on-screen menu. I can see how the initial setup might feel a bit overwhelming for beginners. There are just so many features and customization options to choose from. The remote control that comes with it is really well-designed and responsive. It would have been even better if they had added backlit buttons so it would be easier to use in dim lighting.


The cost of the Onkyo TX-RZ840 is in the mid-to-high range for AV receivers. However, it's worth the price considering its performance and features. But it could be quite expensive for people on a tight budget or those who don't need all the fancy features.



Can the Onkyo TX-RZ840 connect to Wi-Fi and stream music?

Yes, the Onkyo TX-RZ840 has built-in Wi-Fi connectivity, allowing you to stream music wirelessly from various music streaming services, such as Spotify, Pandora, TIDAL, and more. Additionally, it supports AirPlay 2, allowing you to stream music directly from compatible Apple devices.

How can I troubleshoot connectivity issues with the Onkyo TX-RZ840?

If you experience connectivity issues with the Onkyo TX-RZ840, here are a few troubleshooting steps you can try:

  • Ensure that both your receiver and the connected device are running the latest firmware.
  • Verify that the cables are correctly connected and securely plugged in.
  • Restart your receiver and the connected device.
  • If using Wi-Fi, check your network settings and ensure a stable connection.
  • Reset the network settings on the receiver if necessary.

If the issue persists, contact Onkyo customer support for further assistance.
