Product Description

Product Name: Dual channel TPA3116 Bluetooth-compatible 5.0 power amplifier board Input voltage: DC12-24V Amp Chip: Dual TPA3116D2 Bluetooth Version: 5.0 Output impedance: 4~8 ohm Speaker For Speakers: 20W~200W Output power: 2*100W Audio input: Bluetooth-compatible , AUX Number of channels: two channels Size: 110*70*21MM Question and answer: 1. How to choose a power supply? The power supply with the board is critical. The higher the voltage, the higher the current and the better the output power. If you only have 12V 1A, you can bring a 3-4 inch speaker. If you are 19V 5A or above, there is no problem with 8-10 inches, and the power supply must be highly valued. If the voltage is too low, the sound will be distorted after the sound is amplified. If the current is too small, the speaker will pull the voltage low, work abnormally or the sound quality will deteriorate. It is recommended to use 18V19V24V power supply with current above 3A. If you only have 9V12V or 1A 2A power supply, it can also be used but the power is small. Please pay attention to the maximum volume when using it, which may affect the sound quality. 2. How to choose a speaker? Commonly used speakers are generally 4 ohms or 8 ohms, can not distinguish between positive and negative, the effect is the same.If your speaker power is small, it may be used between 10W-30W. The power supply voltage is small to prevent the amplifier from burning out after burning. For example, select a power supply below 15V. If you are a 50W-100w speaker, don't worry about the speaker burnout. You can choose 12-24V power supply. The higher the voltage you choose, the louder the output sound or power.The speaker power is not recommended to exceed 100W, otherwise the sound quality will be affected. 3. Introduction of audio input mode This audio amplifier module has two audio input modes: one is Bluetooth-compatible input and the other is AUX input. Bluetooth-compatible mode is preferred.Bluetooth can be connected in either mode.As long as the Bluetooth-compatible connection is successful is Bluetooth-compatible mode, and Bluetooth-compatible mode support automatic connection.AUX insertion is AUX mode when Bluetooth-compatible is connectionless.It is important to make sure that the Bluetooth-compatible connection of this module has been disconnected when using AUX mode. 4. How to adjust the bass and high pitch? The BASS potentiometer in the middle is to control the BASS, the right BASS is enhanced, the left BASS is attenuated.When the potentiometer is in the middle position, the bass is neither enhanced nor attenuated. The TREBLE potentiometer on the left controls the TREBLE. the right TREBLE enhanced and the left TREBLE attenuated.When the potentiometer is in the middle position, it does not increase or decrease the treble. Note when adjusting treble and bass: when the treble or bass right rotation is adjusted to the maximum, if the sound is distorted, it means that the treble o
