Specification: Origin: Mainland China Product name: 2.1 channel Bluetooth-Compatible audio amplifier module Bluetooth-Compatible version: 5.0 (unobstructed, 15 meters) Input method: AUX + Bluetooth-Compatible Number of channels: 2.1 channels Applicable power supply: DC12~24V/5A or above (cannot be connected to 24V battery pack) Applicable speakers: 20~100W, 4~8Ω Output power: maximum 50W for left and right channels; maximum 100W for subwoofer Protection mechanism: anti-reverse connection, overheating, overcurrent, short circuit protection Product size: 93*89*21mm Tip: Sufficient audio input and sufficient power supply voltage/current can obtain sufficient output power. The higher the power supply voltage, the greater the relative power. Speakers with different impedances also have different output powers. When the voltage and current are sufficient, the greater the ohm number of the speaker, the smaller the relative power. Please make sure that the power of the power adapter is greater than the actual working power of the amplifier. (It is recommended to use a power supply of 12V 5A or above.) How to select the audio input mode This amplifier board has two input modes: Bluetooth-Compatible and 3.5mm AUX interface. When both modes input audio signals at the same time, the amplifier board will give priority to the Bluetooth-Compatible mode; If you need to use the AUX mode, please make sure the Bluetooth-Compatible connection is disconnected.
