    Precision Acoustic Tuning

    Don't let flat audio ruin your listening experience. The independent Treble and Bass EQ knobs allow you to physically shape your sound. Whether you need floor-shaking bass for your EDM tracks or crisp highs for classical music, the perfect audio profile is just a twist away.

    IMPORTANT BUYER'S NOTE (For Max Performance):

    1. Mono Design: This board is a SINGLE CHANNEL (Mono) amplifier. If you want a 2.0 stereo setup, you MUST purchase TWO units and utilize the TWS feature.
    2. Power Supply Requirements: To achieve the true 100W output without audio clipping or restarting, you must use a high-quality power supply of DC 24V with at least 4A-5A of current. Using a 12V 1A/2A plug will significantly bottleneck the volume and bass performance.

    Key Technical Specifications:

    • Amplifier Type: Class-D Digital Mono Amplifier
    • Output Power: 100W Max (at 24V, 4 load)
    • Audio Input: Bluetooth Wireless (Support TWS)
    • EQ Controls: Master Volume, Treble, Bass
    • Operating Voltage: DC 12V - 24V
    • Speaker Impedance: 4 - 8
    • Protection: Over-heat, Short-circuit, Over-voltage
