On the hardware side, 7.2 multichannel pre-outs, powered Zone 2 outputs, and bi-amping capability grant the flexibility to customize. Eight 4K-ready HDMI® inputs including frontside MHL™ enable Dolby® TrueHD and DTS-HD Master Audio™ decoding. Audio processing comes courtesy of Audyssey MultEQ®, Audyssey DSX®, and Dolby® Pro Logic® IIz, while Marvell’s outstanding Qdeo™ technology upscales standard video to 4K. Need music right now? With a tap on your smartphone screen, you can serve lossless audio to your home theater—whether its stored on handset, NAS, PC, or online streaming service—using built-in Wi-Fi, or pair up and stream with onboard Bluetooth technology. Owning an Onkyo A/V receiver is not just about having big sound on movie night—it’s about maximizing the enjoyment of your daily life.
To be awarded THX Select2 Plus certification—the most rigorous performance benchmark for this type of product—the home theater receiver must play at studio reference volume levels with minimal distortion. Select2 Plus is specified for screen-to-seat distances of three to four meters and room volumes of about 56 cubic meters.
The TX-NR828 connects to the wireless home network without LAN cables or adapters. Send a huge range of hi-res, lossless, and compressed files to your home theater from smartphone, PC, tablet, NAS, and online sources using our remote control app. Or pair devices for quality wireless streaming using the built-in Bluetooth technology.
Onkyo’s WRAT (Wide Range Amp Technology) includes discrete low-negative-feedback amplifiers for punchy, true-to-life sound; closed ground-loop circuits to reduce noise; and high instantaneous current to counter impedance fluctuations. Three-Stage Inverted Darlington Circuitry is featured on all channels to handle reference-level playback without distorting.
Audyssey DSX lets you augment your setup with two Front Wide channels, expanding the width of the soundstage, or two Front Height speakers to add a vertical dimension to movies and games. Dolby Pro Logic IIz offers Front Height channels with 7.1-channel upmixing from stereo sources.
The TX-NR828 uses Qdeo technology from Marvell to upscale standard video sources to brilliantly smooth 1080p (for regular HDTVs) and to an incredible 4K on compatible displays.
The TX-NR828 features Powered Zone 2 outputs and Zone 2/3 line-outs. This lets you assign two channels to power audio in a room equipped with speakers. An existing hi-fi system in a third room can also be connected via the line-out, enabling the use of the A/V receiver as a pre-amp and audio server. Control content in all three zones via remote app; play the same song in all zones using Whole House Mode; or enjoy a different song in every room.
THX Select2 Plus components are ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters. THX Loudness Plus is included in the specification.
Selected Onkyo receivers offer 4K (4096 x 2160) upscaling of standard video sources such as 480i/p, 720p, and 1080i/p. Interlaced-to-progressive conversion and scaling are performed by Qdeo video processing technology from Marvell. Qdeo uses algorithms to erase video noise and artifacts such as jaggies and feathering. Played back on a compatible wide-screen display, your content will look more detailed and cinematic than ever.
Selected Onkyo network receivers are able to pass native or upscaled 4K Ultra HD video content from media player through to a compatible 4K TV display or video projector via HDMI.
All Onkyo A/V receivers are capable of carrying high-resolution 3D video formats from source devices to your 3D-capable display via HDMI.
Transporting high-definition (HD) video, 3D encoded HD video, and multi-channel HD audio, HDMI is the most desirable connection for home entertainment. Onkyo’s HDMI-enabled A/V components send and receive HD signals, connecting components such as Blu-ray Disc players, DVD players, media streamers, and gaming consoles to compatible HDTVs. Recent versions of HDMI also incorporate an ARC (Audio Return Channel) for sending audio from the TV tuner through the connected receiver, and for enabling the use of an overlaid high-definition GUI (Graphical User Interface) on Onkyo A/V receivers.
Dolby TrueHD is Dolby’s next-generation lossless technology developed for high-definition disc-based media. Dolby TrueHD audio is bit-for-bit identical to the highest-resolution studio masters. Together with high-definition video, it offers an unprecedented home theater experience. Now listeners can enjoy sound as stunning as the high-definition picture.
Dolby® Pro Logic® IIz
Dolby Pro Logic IIz adds a vertical dimension to your home theater soundstage, delivering an expanded surround-sound experience from any 5.1-channel or stereo source. Dolby Pro Logic IIz enables the inclusion of two Front Height speakers into your surround-sound setup. The Height channels carry ambient, non-directional audio that helps immerse you even more deeply into your movies and games. With Dolby Pro Logic IIz, rain seems to burst from clouds right above you, and helicopters fly realistically overhead.
DTS-HD Master Audio™ is capable of delivering audio that is bit-for-bit identical to the studio master. DTS-HD Master Audio™ delivers audio at super-high variable bit rates—24.5 Mbps on Blu-ray Disc—which is significantly higher than standard DVDs. This bit stream is so fast, and the transfer rate is so high, that it can deliver 7.1 audio channels at a sampling frequency of 24 bits—identical to the original. With DTS-HD Master Audio™, you will be able to experience movies and music exactly as the artist intended: clear, pure, and uncompromised.
Audyssey DSX lets you augment a standard 7.1-channel surround set-up with two “front wide” channels*. Two extra speakers expand the width of the soundstage and help to produce a more realistic and immersive listening experience. Alternatively, Audyssey DSX can be configured to deliver “front height” channels. These channels carry non-directional audio that adds a new vertical dimension to your movies and games.
*Front Wide channels are not available with TX-NR616 and TX-NR609.
Audyssey MultEQ seamlessly equalizes and balances the output of your satellite speakers and subwoofers to suit the unique shape of your listening space, compensating for unwanted acoustic reflections from the walls, floor, and furniture. This creates a more enveloping, cohesive soundstage, projects movie dialog clearly from the center of the screen, and contributes to more convincing directional and ambient effects. Measuring across six listening positions during its one-time setup routine, MultEQ applies two high-resolution filters to satellite speakers and 128 filters to the subwoofer(s). The system also features adaptive low-frequency correction while automatically controlling crossovers, polarity, delays, and levels.
Audyssey Dynamic Volume®
This technology allows you to set the volume level that you want and keep it there, without having to constantly adjust it. By anticipating sudden spikes and dips in the audio soundtrack and compensating for them in real time, Audyssey Dynamic Volume ensures consistent volume levels, regardless of the content you’re enjoying. Thanks to Audyssey Dynamic Volume, quiet dialogue is easier to pick up, loud passages retain their impact, and commercials are less intrusive.
On selected Onkyo receivers/players, interlaced-to-progressive video conversion and scaling are performed by high-quality Qdeo technology from Marvell. Qdeo is a versatile video processor that uses algorithms designed to erase video noise and artifacts such as jaggies and feathering. Played back on a compatible wide-screen display, your Blu-ray Discs and DVDs will look more detailed and cinematic than ever.
WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. A “closed ground-loop circuit” design is employed, in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers to immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current better manages speaker impedance fluctuations, which can negatively affect performance.
192 kHz/24-bit DACs enable the best possible reproduction of standard and high-definition audio formats.
The negative effects of phase-shift—or the timing difference between sound waves of different frequencies—can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Our Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range—allowing vocals and strings to shine—while maintaining a smooth, powerful bass response at all volume levels.
In addition to a Zone 2 line-out, selected Onkyo A/V receivers feature a Zone 3 line-out that allows an audio source to be distributed to a third room equipped with an amplifier and speakers. Users can play up to three audio sources across three zones simultaneously.
Selected Onkyo network receivers feature Powered Zone 2. Two additional surround channels may be assigned to send an amplified audio signal via a set of cables to stereo speakers in another room. An audio source from the receiver may be played back in either or both zones, or two different audio sources played in either room simultaneously.
Selected Onkyo A/V receivers feature licensed InstaPrevue visual input management technology by Silicon Image. InstaPrevue technology displays a series of thumbnail videos on screen representing the available content on devices connected via HDMI. The feature is accessed via the Home Menu screen. InstaPrevue technology makes switching HDMI inputs and choosing content much easier.
MHL (Mobile High Definition Link) is an interface protocol allowing the connection of compatible portable electronic devices such as smart phones to A/V receivers. The protocol transports uncompressed 1080p video stored on smart phone for display on HDTV, with up to 7.1-channels of surround sound. On selected Onkyo network receivers, smart phones can be connected via a designated front-panel MHL/HDMI port. While officially ‘connection agnostic’, MHL cables commonly feature an HDMI plug and Micro USB connector. Once linked to an Onkyo network receiver, the user can control their smart phone using the system remote. Smart phones are recharged upon connection, and no separate power supply for the device is necessary while connected to the receiver.
To achieve Wi-Fi certification, products are tested according to the industry’s 802.11 standards for interoperability, security, reliability, and ease of installation. Products with the Wi-Fi Certified logo have been tested in a variety of configurations and with a diverse range of other devices to ensure compatibility with equipment operating in the same frequency band.
