I had a chance to test this model and this Onkyo TX-RZ820 review will be helpful for people who look for a good receiver that has many great functions. This model combines high power output (moreover, it is THX certified) and a high number of features. The reliable wireless modules allow you to avoid using wires and access various audio streaming services. Onkyo’s technologies are also used to enhance the output audio signal.
The design does not include any unnecessary or fancy elements. It has a large LCD display that shows the most crucial information. It has two knobs on the left side and a big one on the right side. There are also many small buttons on the right side to change the source, control different zones and turn on/off the Bluetooth module. The front flap covers additional buttons (like “sleep”, “info”, “setup”, etc.) and ports (phones, AUX HDMI, setup mic). You can find a huge amount of ports on the backside of this model. It has ports of different kinds so you can connect almost anything you have. Plus, it has two antennas. The device stands on four metal legs.
The Onkyo TX-RZ820 is built well, nothing shakes and the front flap can be closed tight. The weight of this model is 31 pounds. The Onkyo Company used high-quality materials only to build their receivers and this model is not an exception. Overall, it looks stylish, without any unnecessary elements.
Onkyo TX-RZ820 specs prove that this is a great solution for people who need a modern receiver with many features. This model has the THX certificate, which guarantees the high quality of sound. It supports DTS: X and Dolby Atmos formats providing you with pure and powerful sound. It also has a feature of upmixing, letting you experience multidimensional playback. This feature works with DTS Neural:X and Dolby Surround. The sound quality is crucial for Onkyo and to exclude any noises they use Vector Linear Shaping Circuitry (VLSC). It removes noises caused by the digital pulse and outputs analog signal. The Dynamic Audio amplification frequency response ranges from 5 Hz to 100 kHz.
This model supports the 4K video standard at 60 Hz. It is HDCP 2.2 compliant. It also supports Dolby Vision. The HDR10 and HLG support guarantee perfectly clear and vivid colors. Therefore, you can enjoy the high-resolution video without experiencing any motion blurring.
Onkyo TX-RZ820 lets you forget about using wires when it is possible since it has a Bluetooth module and a dual-band Wi-Fi module (5 Ghz/2.4 GHz) with good range and a stable, high-speed connection which is necessary for streaming audio files with a high bitrate. The wireless modules are used to access internet radio stations and various audio streaming services like Tidal, Deezer, Pandora, etc. however, some customers claim that wireless modules may sometimes work with errors resulting losing connection. This model also supports the Chromecast streaming technology, DTS Play-Fi, and FireConnect.
It is capable to distribute content among several zones. It has pre-outs for Zone 3 and powered Zones 2 A/B. However, only HDMI inputs 1-3 can be used for the Zone 2. Another restriction is that you cannot have multi-channel audio in 2 zones simultaneously.
It also has a special application that allows you to tweak different parameters. Sometimes, the remote control may be more useful than the application.
This model would be perfect for people who want to get the high-quality audio and video. It plays 4K video without any stuttering or lagging. The same is true for audio – no lags, even if you use the wireless connection. The audio quality is very high – it is clear and powerful. Plus, this model is THX-certified. However, many customers state that this model suffers from low-quality HDMI boards. As a result, you get lags, artifacts or it just stops working at all.
It has a powerful codec pack that can play almost all kinds of files, so you should not worry about compatibility.
Designing this model, Onkyo combined the high total output power – 900 W with pureness and clarity of sound. The VLSC technology allows you to output a smooth analog signal and the upmixing technology may envelop you with sound using special algorithms. The sound is distortion and lag-free. At the same time, it preserves all details of the sound, even if you set the volume very high. The total power is enough to cover a large room with sound.
It has many ports – 6 rear HDMI ports, main out, Sub out, etc. even 1 front HDMI input. The number of ports makes it possible to connect a great number of devices. It also has wireless modules that allow you to use Bluetooth or Wi-Fi to connect to smartphones or tablets. Moreover, it supports such wireless protocols as DTS Play-Fi and FireConnect.
The process of setting up is not challenging, you need to connect everything up and run the process of audio calibration - (it is automatic and it does not require too much time). The calibration is quite precise but you can always tweak different parameters to make it sound as you wish. Having set up the receiver, you may need to update the firmware, which can make it work more stable and add new features.
Onkyo TX-RZ820 would be a perfect option for people who need a high-performance receiver. This model will cost you around $600. However, it can generate a high-quality audio and video signal. However, this model may have issues with an HDMI board.
Pros of this model are:
