Escape the everyday with spatial surround-sound
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 theater, 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. (Enabled with a future
firmware update.)
Dolby Atmos® and 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, 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. (Enabled with a future firmware update.)
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, 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 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.
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, 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
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 with 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 equalization to all speakers. AccuReflex technology
optimizes 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 localization, a 3D
field with vertical movement and overhead dimensionality is produced.
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-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.
Share the atmosphere or relax in privacy
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
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
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 and 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 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.
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.
