The speakers support 3 modes: 7.1.4，5.1.2 and 2.1.

The system automatically switches sound channels to match different placement scenarios.

7.1.4 Channel System
Supports two placement modes:

Full Separation Mode – All channels operate independently for the most immersive surround sound experience.

Soundbar Mode – Optimized for compact placement while maintaining balanced channel performance.

5.1.2 Channel System
In this mode, the rear surround speakers are placed inside the compartment. The two rear surround speakers function as the center channel, providing stable and focused dialogue output.

2.1 Channel Mode
When all four speakers are docked back into the station, only the two front satellite speakers are active, delivering the left and right channels. In this configuration, the rear surround speakers remain inactive.
