TX-8390

Network Stereo Receiver

Connect your sources to sublime sound

Crafted in exacting detail to tempt hi-fi enthusiasts, the
TX-8390 has connections to amplify all forms of TV-based
entertainment, music, and audio sources. Inputs include

®

, analog and SPDIF audio, phono, Wi-Fi®, Bluetooth®

HDMI
wireless technology, and USB audio. A companion smartphone
app gathers multi-room audio, streaming service management,
and playback controls into one simple interface. GUI with
transparent OSD simplifies setup and operation.

Dynamic Audio Amplification

DAA is our original amplification system. It’s been refined
over decades to reproduce the source as-is while freeing the
emotion in music. Compelling sound is achieved by tuning
each custom part by ear, so the amp not only measures
well, but sounds amazing too. Fast dynamics, wide frequency
response, and an earth-shaking 200 W + 200 W of analog
power are realized with a high-current drive and original amp
topology. High current improves speaker control, extending
driver travel to articulate the entire sound-wave while tracking
each note with absolute precision.

Original custom-built components

Parts such as the High-Current Low-Noise Power Transformer
and 10,000 μF high-current smoothing capacitors are
fabricated to Onkyo’s exclusive specification. Two transistors
on the voltage-amplification stage of each power amp
circuitry boosts current for deep, powerful bass, while the
non-phase-shift amp topology focuses sound through layers of
finely resolved detail. And the extruded aluminum heat sink,
which has heat-dissipating anodized coating, helps suppress
vibration together with the 5 mm-thick aluminum front panel.
This material is complemented by aluminum controls with a
firm, fine actuation.

Built to limit noise

A number of measures contribute to excellent S/N
performance. HDMI board features short signal-paths and
well-finished grounds to assure clean potential. The SoC is
isolated to reduce interference on analog signals. VLSC
output-filter circuitry, meanwhile, erases ultra-high-frequency

™

pulse-modulation noise. The result is clearer sound, improved
instrument separation, and a large, airy soundstage.

Personalized listening with My Input

My Input front-panel selector gives easy
access to any four inputs you choose.
Save your desired start-up volume,
listening mode, and tone settings to
each so your audio starts playing exactly
how you like it in seconds.

Hi-Res Audio in PCM, MQA, or DSD formats

D/A conversion by AKM supports Hi-Res Audio playback up
to 384 kHz/32-bit as well as DSD256, DSD128, and DSD64.
The receiver also includes MQA technology, which enables
you to play back MQA audio files and streams, delivering the
sound of the original master recording. Albums in MQA can be
streamed from supported online services or downloaded to
USB memory or PC/NAS and played back via the TX-8390.

Note: DSD is converted to PCM. When playing MQA files, irrespective of the setting
of the Direct function, the Direct function is automatically enabled at all times.

Enjoy your choice of multi-room audio platform

The TX-8390 is the heart of your home entertainment.
Streaming content from Amazon Music, Spotify
Deezer, and TuneIn can be shared to the TX-8390 and other
supported speakers as part of a multi-room system via Works

Chromecast built-in with the Google Assistant

Stream any music from your smartphone, laptop, or PC to
the receiver with ease. Control playback with Chromecast­enabled apps you know and love from your Android phone
or tablet, Chromebook, Windows
Mac. If you have a device with the Google Assistant, you can

®

PC, or iPhone, iPad, or

find, play, and control music through this and other supported
components just by using your voice.

Works with Alexa

Alexa lets you use your voice to control TX-8390 by directing
your requests through an Alexa-enabled device. Just ask your
Alexa-enabled device, such as an Amazon Echo, to play, pause,
and skip titles or control the volume. You can enjoy music
playback via Amazon Music and make selections by song title,
artist name, release year, or genre.

Note: Requires a future firmware update.

Works with Sonos

The TX-8390 can fit seamlessly with your Sonos Home Sound
System: just pair it with a Sonos Connect. The receiver wakes,
changes inputs, and plays at the desired volume on command
from the Sonos app.

Note: Sonos Connect sold separately. Sonos app is available free for iPad, iPhone, and
Android at the App Store and Google Play.

Music by voice with AirPlay 2 and Siri

AirPlay is an Apple technology designed to control home
audio systems and speakers in any room — with a tap or
by just asking Siri — right from iPhone, iPad, HomePod, or
Apple TV.

Quad-core SoC supports 802.11ac Wi-Fi

A quad-core SoC (System on a Chip) processes multiple tasks
at once and evolves network functions with support for the
high-speed 802.11ac 2x2 MIMO 5 GHz/2.4 GHz Wi-Fi

and the use of Wi-Fi channels. Performance will vary depending on environment.

AccuEQ Stereo with Subwoofer EQ

This is the first Onkyo hi-fi receiver to benefit from AccuEQ
room-acoustic calibration, a technology developed for our
multichannel A/V receivers. AccuEQ creates a harmonious
sound-field even if your speakers aren’t optimally placed. After
detecting speaker size and distance from a measurement
position and setting sound-pressure levels, the system selects a
subwoofer crossover and applies EQ. Enjoy the ideal listening
environment akin to a treated audio listening room.

HDMI Sub/Zone Out modes

The second HDMI output has two modes. Zone 2 mode
shares video from players connected to the receiver to a
second TV and you can watch the same or different content
on either screen. In this mode, the sub display can access
video from HMDI inputs 1–3 only. Sub Out mode is ideal for
projector connection, as it supports signals from all HDMI
inputs. Sub Out can play a single source to either or both
displays simultaneously.

Speaker A/B Drive

Speaker A/B Drive lets you connect
two pairs of speakers at once.
Switch between the speakers you
prefer for hi-fi music listening and
those for general entertainment.
Or place speakers in a different
area and switch playback to that
room (or both). Alternatively,
speaker terminals can be used to
bi-wire compatible loudspeakers
for potential gains in mid- and
high-range sound.
