Q&A1. How to choose a power supply?
The power supply with the board is critical. The higher the voltage, the greater the current, and the more adequate the output power. If you only have 12V1A, you can bring 3-4 inch speakers. If you are 19V
Above 5A, there is no problem with 8-10 inches, and the power supply must be highly regarded. If the voltage is too low, the amplified sound will easily cause sound distortion. If the current is too low, the speaker cannot be brought up.It will pull down the voltage, work abnormally or deteriorate the sound quality.It is recommended to use a power supply of 18V19V24V with a current above 5A. If you only have 9V12V or 1A2A power supply, you can also use it but the power is low, pay attention to the volume when usingThe maximum possible distortion will affect the sound quality.2. How to choose a speaker?
Commonly used speakers are generally 4-8 ohms, and the positive and negative polarity can be distinguished, and the effect is the same. If your speaker has low power, it may be between 20W-50W.It can be used. The power supply voltage should be lower to prevent the loudspeaker from being burnt after amplifying the sound. For example, choose a power supply below 15V. If you are a 100W-200w speaker, don’t worry about itFor the problem of horn burnout, you can choose a 12-24V power supply. The higher the selected voltage, the greater the sound or power that can be output. The speaker power cannot easily exceed 200W, no
It will affect the sound quality.3. Introduction to audio input mode
This audio power amplifier module has two audio input methods: one is Bluetooth input, the other is AUX input, Bluetooth mode is preferred. No matter in which mode Bluetooth can be connectedPick up. As long as the Bluetooth connection is successful, it is in Bluetooth mode, and the Bluetooth mode supports automatic connection back. When Bluetooth is not connected, AUX plug-in is in AUX mode. Need to pay attentionIt is necessary to confirm that the Bluetooth connection of this module has been disconnected when using AUX mode.4. How to adjust treble and bass?
The BASS potentiometer in the middle controls the bass, right-handed bass enhancement, left-handed bass attenuation. 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-handed treble is enhanced, and the left-handed treble is attenuated. When the potentiometer is in the middle position, the treble is neither enhanced nor attenuated.Note when adjusting the treble and bass: when the treble or bass is adjusted to the maximum with the right rotation, if the sound is distorted, it means that the gain of the treble or bass adjustment is too large.You need to turn the treble or bass potentiometer to the left to lower the gain or turn the VOLUME potentiometer on the right to the left to reduce the total volume.5. It's okay if the voice is small, but when the voice becomes louder, the voice becomes muddy?
The sound is distorted, please change to a higher voltage adapter power supply.6. The sound is small, but when the sound becomes louder, the sound freezes?The input power is insufficient, and the power supply itself is protected against intermittent power failure. Please replace it with a higher-power power supply; or if the power is too large, the power amplifier board generates serious heat and thermal protection has occurred.In case, reduce power usage or strengthen heat dissipation.7. What factors are related to the sound quality?The sound quality is not only related to the power amplifier module, but also related to the sound source and the entire sound system. Basically every aspect of the sound system will affect the sound quality, of which the mainThe main links are audio transmission line, audio power supply, tone circuit, power amplifier circuit, speakers and surrounding environment. When only the sound source, power amplifier module and speakers match, the soundQuality is the best.Package Included:1PCSTPA3116 2-Channel 2*100W Bluetooth5.0 Digital Audio Amplifiers BoardShipping Policy
