Onkyo PR-RZ5100: AV Reciever with flagship level quality

Onkyo is committed to creating products that bring joy to listeners. The RZ Series is the culmination of 70 years of experience in high-end audio: forward-looking, but with analogue tradition at heart. Every design element, every hand-selected detail contributes to a flagship level of quality: full range reproduction, sonic transparency and high resolution, lightning-fast dynamics, a sense of rhythm and the soul of the music… performance that captivates you and fills your soul with emotion.

With 11.2 channels of preamp, you can enjoy a full multi-dimensional surround sound experience through a 7.2.4 channel home theater speaker configuration. Object-based Dolby Atmos® and DTS:X™ formats free audio from conventional channels and allow it to move freely above and around viewers’ heads – for the ultimate in immersive 3D audio experience

The THX Ultra2 Plus certified 11.2-channel Onkyo PR-RZ5100 AV processor is the top of the RZ series and supports 4K resolution (60Hz, 2160p), as well as Dolby Atmos and DTS:X 3D audio formats 7.2.4 channel configuration.

The model’s arsenal includes two 32-bit Analog Devices SHARC DSPs, producing up to six billion operations per second, and its digital and analog circuits are completely separated. The following DACs are available on board: two AK4490 chips (32 bit/384 kHz) for front channels, two multi-channel AK4458 (32 bit/768 kHz) and a pair of AK4388 (24 bit/192 kHz) for zones 2 and 3. Clear the signal from pulses noise reduction is helped by VLSC technology. The speaker auto-calibration function is assigned to the AccuEQ system with AccuReflex technology, which allows the speakers for Dolby Atmos to be phase-matched with other speakers. In this case, DSP correction for the “fronts” is not applied in order to ensure natural sound in stereo mode.

AccuReflex is part of the AccuEQ calibration system, which phase-matches the vertical channel speakers with the sounds coming from the other speakers – for transparent and seamless reproduction of object-based surround sound. AccuEQ equalizes and optimizes the surround sound system to match room acoustics without affecting the performance of front speakers designed for pure stereo mode.

In addition to the AM/FM tuner, the AV processor has a wide range of tools for receiving audio content wirelessly, including Bluetooth, Wi-Fi, Google Cast (available with new firmware) and AirPlay. Connection to a local network via LAN/WLAN and playback of Hi-Res formats (including DSD 11.2 MHz) from computers and NAS servers is available. Supported online services include TuneIn and Spotify. FireConnect technology allows you to transmit a signal without using a cable to speakers that support this function and control the broadcast using the application, which is convenient when organizing a multi-room system.


The case has a new design with retro reminiscences. The volume knob is located on the right side of the aluminum facade. Above it there are buttons for selecting a source and for working with additional zones. The left side is occupied by power/standby keys and Pure Audio mode activation keys, as well as a pair of tandems (button + rotary knob) for selecting listening modes and adjusting timbres. In the center there is a display with a cover underneath that hides controls for various functions of the processor, as well as an HDMI input, a 6.3 mm headphone jack and a jack for a calibration microphone.


The model has wide switching capabilities. Five of the seven HDMI inputs on the rear of the case and two HDMI outputs support the HDCP 2.2 4K content copy protection protocol. You can also select 11.2-channel output in balanced and unbalanced versions, MM phono preamp connectors, USB port and RCA outputs for zone 2 and 3.
