Bluetooth Amplifier Module Motherboard Audio Decoding With High-Pressure Bass Tuning TPA3116D2 Chip Audio Amplifier

Brand: OtherOutput: 90V 

Question Answer:

1. How to Select a Power Supply? The Power Supply of the Board Is Crucial. The Higher the, the Larger the, the More Sufficient the Output Power. If You Only Have 12V 1A, You Can Bring 3-4-Inch Speakers. If You Are above 19V 5A, It Is No Problem to Bring 8-10 Inches, and the Power Supply Must Be Highly Valued. If the Is Too Low, Sound Distortion Will Easily Be Caused after Sound Amplification. If the Is Too Small to Bring up the Speaker, the Will Be Pulled down, and the Work Is Abnormal Or the Sound Quality Will Deteriorate. Recommend Use 18v19v24v Power Supply with a of More than 5A. If You Only Have 9v12v Or 1A 2A Power Supply, You Can Also Use It but the Power Is Small. Note That When You Use It, the Volume Will Be Distorted to the Maximum, Which Will Affect the Sound Quality.
2. How to Choose a Speaker? Commonly Used Speakers Are Generally 4-8 Ohm, Which Can Not Distinguish Positive and Negative Polarity, and the Effect Is the Same. If Your Speaker Power Is Small, It May Be Available between 20w-50w. the Power Supply Is Smaller to Prevent the Speaker from Burning after Amplification. for Example, Select a Power Supply below 15V. If You Are a 100W -200W Speaker, Don't Worry about the Problem of the Speaker Burning out, You Can Choose a Power Supply of 12-24V. the Higher the, the Greater the Sound Or Power That Can Be Output. The Speaker Power Is Not Easy to Exceed 200W, Otherwise It Will Affect the Sound Quality.
3. Introduction to Audio Input Mode There Are Two Audio Input Methods for This Audio Amplifier Module: One Is Blueinput, the Other Is Aux Input, and Bluetooth Mode Takes Precedence. Bluetooth Can Be Connected in Either Mode. As Long as the Bluetooth Connection Is Successful, It Is Bluetooth Mode, and Bluetooth Mode Supports Automatic Connection Back. When Bluetooth Is Not Connected, Aux Is Inserted in Aux Mode. Note That When Using Aux Mode, Make Sure That the Bluetooth Connection of This Module Has Been Disconnected.
4. How to Adjust the Bass? The Bass Potentiometer in the Middle Controls Bass, Right-Hand Bass Enhancement and Left-Hand 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-Hand Treble Is Enhanced, and the Left-Hand Treble Is Attenuated. When the Potentiometer Is in the Middle Position, the Treble Is Neither Enhanced Nor Attenuated. Note When High and Low Pitch: When the Right Rotation of the Treble Or Bass Is Adjusted to Close to the Maximum, If the Sound Is Distorted, the Gain of the Treble Or Bass Adjustment Is Too Large, and the Treble Or Bass Potentiometer Needs to Be Left-Handed, reduce the Gain Or the Volume Potentiometer on the Right to the Left to Reduce the Total Volume.
5. It's Okay If the Sound Is Small. When the Sound Becomes Larger, the Sound Becomes Cloudy? The Sound Is Distorted. Please Change the Level to Power Adapter Higher.
6. It's Okay If the Sound Is Small. When the Sound Becomes Larger, the Sound Is Stuck? The Input Power Is Insufficient, and the Power Supply Itself Is Intermittently Powered off. Please Replace the Power Supply with a Higher Power Supply. Or If the Power Is Too Large, Amplifier Board Heating Is Serious, and Thermal Protection Occurs, Reducing Power Usage Or Strengthening Heat Dissipation.
7. What Factors Do the Quality of Sound Quality Have to Do? The Sound Quality Is Not as Good as the Power Amplification Module, but Also Related to the Sound Source and the Whole Audio System. Basically, Every Link of Audio System Will Affect the Sound Quality, Among Which the Main Links Are Audio Transmission Line, Audio Power Supply, Tone Circuit, Power Amplifier Circuit, Sound and Surrounding Environment. Only When the Sound Source, Power Amplification Module and Speaker Match Can the Sound Quality Play a Very Good Effect.
