TheOnkyo TX-RZ900 7.2-Channel Network AV Receiveris designed to deliver reference grade audio quality, complete with a custom high-grade toroidal transformer. This receiver features a high-current amplifier design and delivers up to 140W per channel at 8 ohms for robust audio playback. Integrated Advanced AccuEQ room calibration uses the included microphone to automatically adjust sound parameters according to the characteristics of your listening environment. Built-in AirPlay and Bluetooth allow you to wirelessly stream music from compatible audio sources such as computers, MP3 players, smartphones, and tablets. On-board Wi-Fi and Ethernet connectivity gives you the ability to stream music from Internet radio sources and use DLNA technology to share content with compatible networked devices. Two Wi-Fi antennas are on the rear of the receiver for optimized signal range.
The Onkyo TX-RZ900 has eight HDMI inputs for interfacing audio and video sources and the pass-through of 3D and 4K video sources. It is also HDCP 2.2 compliant, with dedicated HDMI ports. Other connectivity options include digital optical, digital coaxial, stereo RCA inputs, and more. These interfaces allow you to connect a wide variety of source components. Its dual HDMI outputs allow you to connect to external displays. Onkyo also offers a free remote app for controlling your receiver from a smartphone or tablet. Built-in high-resolution audio support allows you to take advantage of dynamic surround sound formats like DTS-HD Master Audio and Dolby TrueHD.
Custom Toroidal Transformer and Hi-Current Amps
The TX-RZ900's custom toroidal transformer and capacitors help to reproduce ultra low frequencies down to 5 Hz. Its high-current amplification system also enables enhanced control of the speakers for accurate and dynamic sound.
Realistic Audio Quality
With parallel "push-pull" amplification, the receiver's transistors alternately "push" and "pull" the current. In pairs, one output device (i.e. a transistor) will amplify the positive half of the waveform, while another output device will amplify the negative half of the waveform. Push-pull amplification has the advantage of efficiency, but it can be affected by occasional distortion. Onkyo has countered this by including a three-stage inverted Darlington circuit to significantly reduce distortion.
Three-Stage Inverted Darlington Circuitry incorporates a low negative feedback design that is designed to result in natural sound. This circuitry gives the amplifier power, high instantaneous current, and efficiency.
Vector Linear Shaping Circuitry (VLSC)
Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the signal in its original form following processing. Unlike conventional filters, VLSC removes pulse noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity for a smooth analog signal. The signal's data is converted between sampling points and joined with analog vectors in real time to produce a smooth output wave form. The result is designed to be virtually noiseless and smooth while revealing the subtle nuances in music sources.
THX Select2 Plus
The TX-RZ900 meets the demanding and rigorous performance guidelines for THX Select2 Plus certification. To achieve this, it has to pass 2,000 tests across 75 test categories, covering 14,000 data points. THX Select2 Plus is recommended for a screen-to-seat viewing distances of 10-12'.
DTS:X is an object-based surround sound technology that includes height channels to deliver a fully-immersive listening experience. DTS:X provides listeners with flexibility, immersion, and interactivity. Unlike channel-based audio, you will be able to personalize your audio experience. For example, you can turn up just the dialog within a mix. DTS:X allows you to customize to your room layout as well as control dialog and dynamic range.
Supports Dolby Atmos Up to 5.1.2-Channels
This format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the room. This is designed to create a realistic and captivating sonic atmosphere. Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels. Additionally, the Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system. Please see the manufacturer's website for DTS:X availability.
Ready for Ultra HD
This receiver supports HDCP 2.2 compatibility. This HDMI specification offers an increase in bandwidth (up to 18 Gb/s) to support features such as 4K at 50/60 Hz (2160p), which offer 4-times the clarity of 1080p/60 Hz video resolution, and 4:4:4 color space. This Onkyo receiver also enables the transmission of High Dynamic Range (HDR) formats, and provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image.
Multi-Zone Audio and Video
The TX-RZ900 features powered zone 2 and zone 2/3 pre/line-outs for distributed audio playback, including Zone 2 digital audio and network audio output. You can control the audio content in the zones via the free remote app; play the same song in all zones using whole house mode; or enjoy a different song in each room.
Furthermore, there is a Zone 2 HDMI output for HD video in a second Room, with Zone 2 HDMI supported on inputs 1, 2, 3, 4 & 5. Use the HDMI sub out to connect a second display in another room. This allows you to route 1080p content from the media players connected to your receiver and play it back on another TV with easy smartphone control.
Convenient Control Options
An RS232 input, an IR input, and a 12 Volt Trigger out give the TX-RZ900 an array of control capabilities.
Bluetooth, AirPlay, and Wi-Fi
The TX-RZ800 has Bluetooth, AirPlay, and Wi-Fi technologies built-in. The free Onkyo Remote app puts a range of streaming options at your fingertips, from universal hi-res audio via network-attached devices to internet streaming services to music on your smartphone and tablet. You can also wirelessly stream audio from your Bluetooth sources directly to the receiver. It also comes loaded with Spotify, Pandora, SiriusXM Internet Radio, Slacker, and TuneIn. You can select a station and search for music available on these services via the Onkyo Remote app on your smart device.
This receiver incorporates a premium-quality AK4458 digital-to-analog converter (DAC) from Asahi Kasei. This DAC implements unique low-distortion filtering technologies for clear sound, that's designed to unlock the potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).
