Choose a speaker layout to suit your room, from a space-saving 2.1-ch setup enhanced with 3D surround-sound courtesy Dolby Atmos Height Virtualizer* or DTS Virtual: X® to a 3.2.2 channel system for native object-audio playback. Whatever way you play it, dynamic power is ready to thrill thanks to authentic high-current analog amps backed by a thumping custom transformer. For true-to-life video, the AVR supports 4K/60p and HDR video passthrough. If all this tech sounds scary, relax: every aspect of this product is designed to erase frustration, from the automated AccuEQ system calibration to a quick connection guide. The receiver integrates your players and TV and adds practical features such as a Vocal Enhancer for clear dialog. There’s even a Zone B line-out to distribute all your home theater sources to a component with an analog RCA line-in, such as a wireless headphone dock or hi-fi system. Or just sit back and stream from apps via Bluetooth® technology and let Advanced Music Optimizer™ enrich every note of the golden Onkyo sound.
