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.
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 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 mirrors whatever's playing on your mobile device, laptop, or PC on the home theater. Devices supporting Qualcomm® aptX codec deliver virtually lossless low-latency playback, while original Advanced Music Optimizer mode enriches any compressed audio for a more satisfying musical experience
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.
Connections to speakers and external devices are clearly labeled and illustrated on the rear panelthe connection diagram is readable upside down to make things easy when you're leaning over the top of the receiver.
