Onkyo TX-SR393 5.2-Channel Network A/V Receiver

Premiere Dolby Atmos® and DTS:X® sound at home with the TX-SR393. Choose a speaker layout to suit your room, from a space-saving 2.1-ch setup enhanced with 3D surround-sound courtesy Dolby Atmos Height Virtualizer or DTS Virtual:X® to a 3.2.2-ch system for native object-audio playback. Whatever way you play it, dynamic power is ready to thrill thanks to authentic high-current analog amps backed by a thumping custom transformer. For true-to-life video, the AVR supports 4K/60p and HDR video passthrough. If all this tech sounds scary, relax: every aspect of this product is designed to erase frustration, from the automated AccuEQ system calibration to quick connection guide. The receiver integrates your players and TV and adds practical features such as Vocal Enhancer for clear dialog. There’s even a Zone B line-out to distribute all your home theater sources to a component with an analog RCA line in, such as a wireless headphone dock or hi-fi system. Or just sit back and stream from apps via Bluetooth® technology and let Advanced Music Optimizer™ enrich every note of the golden Onkyo sound.

  • Dolby Atmos® and DTS:X® sound is here
    The TX-SR393 supercharges your Dolby Atmos® and DTS:X® experience. Object-based audio is mixed in 3D space and lets any sound play through any speaker, tracking the action, localizing effects, and moving around you. Dolby Surround® and DTS Neural:X® complement native 3D audio playback. These technologies find localization cues in legacy stereo or multichannel soundtracks and upmix these elements to create immersive top-to-bottom dimensionality.
  • Dolby Atmos Height Virtualizer
    When playing any Dolby® format, engaging Dolby Atmos Height Virtualizer enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers. 
  • Ready for 4K HDR entertainment®
    Enjoy comprehensive support for 4K/60p and HDR (High Dynamic Range) video formats including HDR10, HLG, Dolby Vision®, and BT.2020. The 4:4:4 color-space is also supported. All four HDMI® inputs and ARC-ready output, pass video from player to your compatible TV and projector and all terminals are HDCP 2.3 compliant. Unlock everything the latest films and games have to offer. You can easily confirm A/V input-output status via a new OSD window. 
  • More power, more realism, more magic
    It's tempting to see watts as the most important figure on an amp's spec sheet. However, watts are an indication of loudness, not sound quality. Amperes-electrical current- tell the real story. The more current an amplifier develops, the better it controls the speakers. Better control equals fast transient response, wide dynamic range, and clear, accurate sound. The high-output transformer, large capacitors, and discrete amps inside the TX-SR393 produce the most current in its class. And that's one big reason why it sounds as good as it does.
  • Smooth and easy Bluetooth® streaming
    Whatever audio is playing on your phone, tablet, or PC app can be streamed to the TX-SR393 with Bluetooth wireless technology. Once the receiver has paired with and remembered your device, it will start playback automatically whenever it detects an incoming Bluetooth audio stream.
  • AccuEQ Room Acoustic Calibration with AccuReflex™
    AccuEQ creates a harmonious soundfield in your room. It detects speaker presence, size, and distance from a measurement position, and sets sound-pressure levels. It then selects the ideal subwoofer crossover and applies equalization to all speakers. AccuReflex optimizes object-based audio reproduction through Dolby Atmos-enabled speakers. It resolves phase-shift arising from path differences between directional and non-directional sounds. Enjoy improved localization and a 3D field with vertical movement and overhead dimensionality.
  • Decompress with Advanced Music Optimizer™
    When an audio file is squeezed into a small container (such as MP3), high-frequency data is lost. This can affect sound quality. Onkyo's Advanced Music Optimizer DSP listening mode reconstructs the missing bit data. Playback quality is greatly improved, while you enjoy the same convenient file sizes. This mode also optimizes Bluetooth streaming playback quality.
  • Spatial sound elevated with DTS Virtual:X®
    DTS Virtual:X is a new surround-sound virtualization technology that creates an immersive 3D soundfield from any speaker layout, such as 2.1, 3.1, and 5.1 configurations without height, surround, or rear surround speakers deployed. It uses sophisticated DSP-based algorithms to place the audience at the center of a multidimensional soundfield with height and surround spatiality, and is equally effective in large or small spaces. DTS Virtual:X works in the 3D domain with DTS:X soundtracks, DTS formats, and non-encoded stereo.
  • Hear dialog clearly at the touch of a button
    Finally, a fast and effective solution to inaudible dialog in TV programs and movies. The TX-SR393 features DSP-controlled Vocal Enhancer that identifies vocal frequencies and allows you to raise or lower them to taste using keys on the remote or via the tone controls on the receiver's front panel.
  • Powered Zone B Audio or front-channel bi-amping
    The Height/Surround Back/Bi-Amp/Zone B speaker outputs can drive stereo speakers in another room with a 5.2-ch setup in the main room. The outputs can share any AVR source exclusively in Zone B, or play the same source in Main and Zone B. Alternatively, you can bi-amp your pair of compatible Zone B. Alternatively, you can bi-amp your pair of compatible front speakers. 
  • Share the atmosphere or relax in privacy
    A fantastic addition to the TX-SR393 is a Zone B line-out. It connects a component with an analog RCA line input to audio sources available to the receiver, including HDMI and digital audio. Share sound to a hi-fi in a nearby space, or connect a supported charging transmitter dock for wireless headphones and enjoy your entertainment without disturbing anybody.
  • USB power for streaming dongles
    A USB port on the rear panel powers any media streaming stick plugged into an adjacent HDMI input-great if you don't have enough power-points. 
  • Simple steps to sweet sound
    The TX-SR393 simplifies your room's entertainment setup. Components plug into labelled ports while your TV connects via one easy-to-conceal HDMI cable. Hook up your speakers as shown by a friendly diagram next to the numbered speaker terminals. Setup takes moments, enjoyment is limitless.
