4K Ultra HD video support
Four HDMI in and 1 out support not only multichannel audio but also 4K Ultra HD video, with HDCP 2.2 compliance, so you can enjoy the next generation of copy protected 4K Blu-ray and other Ultra High Definition content at up to 60Hz.
HDMI video up-conversion takes all your various inputs, whether component, HDMI, or composite, and sends it all to your TV through a single HDMI cable.
Easy configuration and EQ calibration
AccuEQ room acoustic calibration measures level, distance, and crossover for all speakers, and the subwoofer, and then conducts a second measurement to eliminate standing waves. You can include or bypass the EQ measurement for front and left speakers, set the EQ manually, or select from presets.
Rear panel features easy connection diagrams that clearly illustrate how to connect speakers and external components, so you don't have to fumble with a manual, or pull your hair out in frustration when you can't find it.
Bluetooth wireless and audio enhancement
Bluetooth version 2.1 + EDR (Enhanced Data Rate) supports high-quality wireless audio. You can pair up to 10 compatible devices and enjoy music from your computer, smartphone, tablet, Apple TV, and more.
Advanced Music Optimizer improves compressed digital audio, including Bluetooth streamed music. Phase-Matching Bass Boost further enhances the sound to ensure deep bass and clear mid-range.
