MakerHawk Bluetooth Amplifier Board 2.1 2X50W+100W 12V-24V Audio Power Amplifier Module Bass and Treble Control for Store Home Theater Speakers with Antenna

Parameter Model: ZK-MT21 Bluetooth Version: 5.0 (without occlusion 15m) Audio Input: AUX + Bluetooth Channel: 2.1 Input sensitivity: 500mV Adaption Supply Voltage: 12-24V / 5A above (Do not connect to 24V battery pack) Speaker: 20-100W, 4-8Ohm Output Power: max 50W @R&L channel; max 100W @subwoofer Protection Mechanism: anti reverse connection, overheating, overcurrent, short circuit protection Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please ensure that the power of the adaptor is greater than the actual working power of the amplifier. Features: * [2-in-1] High quality power amplifier board. With AUX and Bluetooth two audio input methods, 2-in-1. 5.0 Bluetooth version, the tra...
