Wired connectivity includes four HDMI inputs, one optical, one digital coaxial, and three stereo RCA audio inputs. The HDMI ports support 4K resolution, HDR10, HLG, and Dolby Vision, which can be passed through to your display via the HDMI output; this output supports ARC for the reproduction of display-based audio, such as that from built-in apps like Netflix or YouTube.

The included speaker package features a 5.1-channel configuration, with two front speakers, a center channel, two surround speakers, and a 6.44" down-firing passive subwoofer. The receiver also supports Dolby Atmos and DTS:X with these speakers in a 3.1.2-channel setup.

Dolby Atmos and DTS:X Compatibility

Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the sound designer the ability to precisely place sounds anywhere in the 3-dimensional space. The included receiver features the ability to connect the included speaker system in a 3.1.2-channel setup, using the two rear speakers instead as overhead speakers. DTS:X similarly decodes audio and seems to place the sound in the direction your video dictates it should come from, rather than seeming to come from your speakers.

Dolby Surround and DTS Neural:X

These two technologies find localization cues in legacy stereo or multichannel soundtracks and upmix them to create more immersive vertical dimensionality.

Elevated Sound with DTS Virtual:X

This technology is designed to create an immersive 3D soundfield from virtually any speaker layout, such as 2.1, 3.1, or 5.1, with no need for height, surround, or rear surround speaker connection. It uses DSP-based algorithms to place you at the center of a multidimensional soundfield with height and surround spatiality, and can be effective in small or large spaces. It works with DTS:X and DTS formats as well as non-encoded stereo.

Space-Saving Speaker Design

The included speaker system features a compact design, with full-range drivers and large magnets. Their compact size helps provide easy placement, even on the wall, while their cloth-wrapped baffles help protect them from young children. With a small 9.1 x 13.1" footprint and a down-firing 6.4" cone, the subwoofer can be placed nearly wherever you want to add deep bass to your games and movies.

HDR & 4K Support via HDMI

Each of the receiver's HDMI terminals support 4K/60 Hz, HDR10, HLG, Dolby Vision, BT.2020, 4:4:4 video, and HDCP 2.2. The HDMI output supports Audio Return Channel (ARC) for the reproduction of display-based audio, such as integrated apps. You can confirm the A/V input/output status via an OSD window.

Discrete Amps

The receiver's discrete amplifiers, high-output transformer, and large capacitors are designed to deliver high current to the speakers to help provide better speaker control for fast dynamics range, and clear, accurate sound.

Clear Dialogue with the Touch of a Button

The receiver features DSP-controlled Vocal Enhancer that identifies vocal frequencies and allows you to raise or lower them to your taste using the keys on the remote or via the tone controls on the receiver's front panel.

Zone B Line-Out

The Zone B line-out lets you connect a component with an analog RCA line input to audio sources connected to the receiver, including digital audio via optical or digital coaxial. Share sound to a nearby space, or connect a supported transmitter for your wireless headphones to enjoy your media without disturbing those around you.

Designed for Simple Setup

A single HDMI cable connects the receiver to your display, and the diagram on the rear panel helps make speaker setup easy.

Bluetooth with Advanced Music Optimizer

Bluetooth wireless technology sends whatever is playing on your compatible mobile device, laptop, or computer to your home theater. Compressed audio, such as MP3 or AAC files stored on your smartphone, is enhance dbyt he Advanced Music Optimizer, a DSP technology designed to restore high-frequency bit data for rich, clear sound.

Connect and Power Your Media Streaming Device

A rear-panel USB power output supplies power to select HDMI media streaming devices, allowing you to upgrade your home theater with on-demand network entertainment without additional power cords.

Dolby Atmos Height Virtualizer, Available via a Future Firmware Update

When playing any Dolby format, engaging the Dolby Atmos Height Virtualizer can create virtual surround and height effect from traditional speaker layouts without the need for additional height or surround speakers. This feature is scheduled to be made available via a future firmware update.

Buying a Onkyo Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it's repackaged with accessories included. When you consider that a factory-renewed Onkyo product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Onkyo repair center (you can look-up locations online here or call 800-229-1687)

Onkyo, like all electronics manufactures, receives products returned for various reasons. In 2023 consumers returned 23 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened, it must be resold as refurbished or open box and cannot be resold as new again. The history and reason why a product was returned is not provided to us, thus we cannot provide any additional details regarding its past. All products are processed by Onkyo certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Onkyo Factory Refurbished" product.

Most (not all) units are cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we cannot provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
