## Features and Documentation

=== "Key Features"
    - 5.8GHz Wi-Fi wireless audio link, low latency, strong anti-interference, stable and reliable (supports up to 10 channels transmission, depending on project configuration).
    - ZeroConfig first power-on guidance and Web visual configuration, supporting auto-reconnection.
    - Scenario-based channel configuration: standard 5.1, compact 3.1, minimalist 2.1, expandable to 7.1.2; flexible channel mapping and device grouping.

=== "Wireless Audio Transmission"
    - 5.8GHz Wi-Fi wireless transmission, up to 20 meters range, optimized audio link latency and jitter, supporting multi-point connection between host (Soundbar) and rear surround/subwoofer.
    - Multi-link collaboration and anti-interference strategy: automatic channel selection, reconnection and fault tolerance, adapted to complex environments.
    - BLE-based for fast pairing/auxiliary configuration (depending on hardware platform capabilities).

=== "Audio Specifications and Synchronization"
    - Support for multiple high-resolution audio formats: PCM default up to 192kHz/48bit.
    - Dynamic range optimization and buffer synchronization strategy, ensuring high fidelity and stable playback, reducing stuttering and desynchronization.
    - Support master-slave switching, playback latency 20ms.

=== "Channels and Roles"
    - Role definitions: Host (Soundbar/Master), Rear Surround (Rear L/R), Subwoofer (Sub), supporting custom extensions.
    - Channel mapping: Support intuitive assignment of channels to devices in Web configuration, adapted to different room layouts.
    - Device grouping and networking: Support group ID and auto-discovery, facilitating parallel deployment of multiple systems.

=== "Web Configuration"
    - Configuration center: Network (AP/STA), device pairing, channel mapping, channel test playback.

> The above hardware parameters and capabilities refer to the Realtek `RTL8711Dx` series module specifications, subject to actual model selection and datasheets.
