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 the need for additional surround or height speakers.

Dolby Atmos & DTS:X

Supports Dolby Atmos and DTS:X for an immersive three-dimensional sound-space through 5.1.2-channels. Connect an outboard power amp via Zone 2 pre-out for 5.1.2 in the main Zone with 7 channels of internal amplification, and a different source in stereo in Zone 2.

Integra products are designed and engineered to meet the demands of leading custom installers. CI Centric features such as Web Setup, Onboard HDMI Diagnostics, and compatibility with Remote Monitoring systems like OVRC Pro and Domotz make Integra AVRs the choice of the modern integrator. Optional rack mount kits provide a clean, finished look when installed in racks and cabinets, while a unique bright white back panel facilitates connections in hard-to-reach areas.

Klipsch Optimize Mode allows you to easily integrate your Klipsch Reference and Reference Premiere speakers seamlessly with your Onkyo AV receiver. Klipsch and Onkyo teamed up to implement precise crossover values for specific new Reference Premiere speakers. Now, you can simply select the model speakers you’ll be using for each individual channel, and the optimized crossover setting will be automatically applied.
