• AccuEQ Calibration Ready: AccuEQ streamlines the initial setup of your home theater system and ensures your receiver and speakers are properly calibrated for the best performance in your listening space. AccuEQ calculates speaker distance from the listening position, adjusts speaker sound pressure level, and sets the speaker crossover. The latter selects the correct point to roll off low-frequency sound to the subwoofer. The result is clear and balanced full-spectrum surround sound.
• Dolby Atmos® And Dts:X® – Setting Sound Free: Dolby Atmos® and DTS:X® formats allow engineers to map sound anywhere in 3D space, effects moving from speaker to speaker all around the room and wrapping your audience in the latest films and games. You can also enjoy your 3D speaker layout with classic titles. Dolby Surround® and DTS® Neural:X find overhead cues in legacy soundtracks and upmix for awesome spatial realism.
• 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 employing additional surround or height speakers.
