HDMI® Connects You to the Future

Connect your players with just one cable linking to the TV for
clean AV unit installation. HDMI terminals pass the latest
video formats to your display, including those supporting
4K/60 Hz, HDR, BT.2020, and HDCP 2.2. There’s also an
Audio Return Channel (ARC) for amplifying TV broadcasts.

Amp Power Adds Thrills to Music, Movies, Gaming,
and TV Programs

Discrete analog amps (not an all-in-one integrated circuit)
deliver high instantaneous current to the speakers for dynamic
audio reproduction. Controlled power is the cornerstone of
Onkyo’s amplification philosophy.

AccuEQ Room Acoustic Calibration

AccuEQ sets essential speaker conditions such as distance,
output, and crossover, and EQs for a clear and balanced audio
image that’s free from distortion
caused by the acoustics of your
listening space.

Bluetooth® Wireless Technology

Bluetooth® wireless technology can stream whatever’s

playing on your mobile device, laptop, or PC to the home
cinema. Use Onkyo-original Advanced Music Optimizer
mode to enrich any compressed audio for a more satisfying
musical experience.

(Streaming device not included)

Enjoy Music via USB Input

Connect a compatible USB memory device filled with MP3,
WMA, or AAC audio files to enjoy clear and powerful
reproduction of your music. Quality D/A conversion and a
selection of DSP listening programs further enhance sound to
suit different kinds of music.

Easy Connection Guide Simplifies Setup

Connections to speakers and external devices are clearly
labeled and illustrated on the rear panel—the connection
diagram is readable upside down to make things easy when
you’re leaning over the top of the receiver.
