Specification: Origin: Mainland China Type: Voltage Regulator Condition: New Application: Speaker Model Number: Digital Power Amplifier Board Ultra-thin TPA3110 digital power amplifier board audio DC12-24V audio power amplifier board 15w * 2 Product parameters: Input voltage: DC 8-24V Output power: 8Ω 2*15W Number of channels: dual-channel stereo Audio input: LGR three-wire audio input Product size: 40*30*2mm Product use: Audio power amplification Attebtions: 1. This amplifier board must use DC DC power supply, requiring better performance of the switching power adapter. 2. Can not use AC transformer, if the use of AC transformer, must be rectified, filtering circuit into pure DC DC can be used. 3. DC power supply: voltage DC12V-24V / current power more than 2A, must be clear positive / negative, cut over DC24V voltage use, otherwise burn IC chip! 4. can be connected to speakers or speakers 4Ω or 8Ω, power between 10W-80W, this depends on the power supply size to determine the power of the speaker. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
