Samsung's HW-F450 supports ARC (Audio Return Channel). In the past, connecting multiple devices required several cables, quickly leading to a mess of wires. Today, HDMI with ARC allows everything to be transmitted in both directions with just one cable: video and audio out, and audio back.

Powerful bass requires large enclosures, but these often don't match the sleek TVs of today. That's why your soundbar shares the workload: the slim soundbar handles the high frequencies, while the bass is delivered wirelessly from the subwoofer.

Features include Bluetooth audio, lip sync correction (0 - 200 ms), 6 sound modes, auto power with audio detection, a wireless subwoofer, and ARC (Audio Return Channel).
