From easy Bluetooth wireless streaming to the heart-pounding thrills of Dolby Atmos and DTS:X soundtracks, the TX-SR494 deepens enjoyment of daily life with great sound and smart features. Seven channels of high-current power give you freedom to choose a speaker layout that suits. Dolby Atmos Height Virtualizer or DTS Virtual:X place sound overhead or behind if you don’t want height or surround speakers and both Dolby Surround and DTS Neural:X are on board. Rear surrounds, bi-amped front speakers, or Powered Zone B audio are also an option. AccuEQ with subwoofer EQ and AccuReflex for 5.2.2-ch Dolby Atmos-enabled systems clarify sound in any space. As the heart of your home cinema, the TX-SR494 has HDMI terminals supporting HDR and 4K/60p video, while the GUI with OSD over HDMI, Zone B pre-/line-out, and Vocal Enhancer function make this receiver a joy to use as well as hear. 

Dolby Atmos & DTS:X Sound Is Here

Dolby Atmos & DTS:X Sound Is Here

The TX-SR494 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, localising effects, and moving around you. Dolby Surround and DTS Neural:X complement native 3D audio playback. These technologies find localisation cues in legacy stereo or multichannel soundtracks and upmix these elements to create immersive top-to-bottom dimensionality.

Spatial Sound Elevated w/ DTS Virtual:X

Spatial Sound Elevated w/ DTS Virtual:X

DTS Virtual:X is a new surround-sound virtualisation technology that creates an immersive 3D soundfield from any speaker layout, such as 2.1, 3.1, 5.1, and 7.1 configurations without height, surround, or rear surround speakers deployed. It uses sophisticated DSP-based algorithms to place the audience at the centre 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.

Dolby Atmos Height Virtualiser

Dolby Atmos Height Virtualiser

When playing any Dolby format, engaging Dolby Atmos Height Virtualiser enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.

íReady for 4K HDR Entertainment

íReady 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, unlocking 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

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-SR494 produce the most current in its class. And that’s one big reason why it sounds as good as it does.

AccuEQ Room Acoustic Calibration w/ AccuReflex

AccuEQ Room Acoustic Calibration w/ AccuReflex

AccuEQ Room Acoustic Calibration creates a harmonious soundfield in your room. It detects speaker presence, size, and distance from a measurement position, and sets appropriate sound-pressure levels. It then selects the ideal subwoofer crossover and applies equalisation to all speakers. AccuReflex technology optimises reproduction of object-based audio through Dolby Atmos-enabled speakers. It resolves phase-shift arising from path differences between directional and non-directional sounds. Along with improved localisation, a 3D field with vertical movement and overhead dimensionality is produced.

Finally, a fast and effective solution to inaudible dialog in TV programs and movies. The TX-SR494 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.

A fantastic addition to the TX-SR494 is a Zone B pre-/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.

Powered Zone B Audio or Front-Channel Bi-Amping

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 front speakers.

Simple Steps to Sweet Sound

Simple Steps to Sweet Sound

The TX-SR494 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.

Smooth & Easy Bluetooth Streaming

Whatever audio is playing on your phone, tablet, or PC app can be streamed to the TX-SR494 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.

Decompress w/Advanced Music Optimiser

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 Optimiser DSP listening mode reconstructs the missing bit data. Playback quality is greatly improved, while you enjoy the same convenient file sizes. This mode also optimises Bluetooth streaming playback quality.

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.
