Use high-quality materials with guaranteed quality<br /><br />2. Small size and exquisite appearance<br /><br />3. Easy to use<br /><br />4. Stable performance<br /><br />5. Wide range of applications<br /><br /><br /><br />Parameters:<br /><br />Product Name: 20W+20W Stereo Bluetooth Digital Amplifier<br /><br />Product Model: XY-AP15H<br /><br />Supply voltage: DC: 8-24V (the higher the voltage, the greater the output power)<br /><br />Bluetooth version: 5.0<br /><br />Transmission distance: 15 meters (unobstructed)<br /><br />Number of channels: left and right dual channels (stereo)<br /><br />Compatible speaker: 30W-200W 4 &Omega; 8 &Omega; 16 &Omega;<br /><br />Protection mechanism: power reverse protection, short circuit protection, self recovery overheating protection<br /><br /><br /><br />Note: The output power of the power supply should be greater than that of the amplifier, otherwise it will affect the sound<br /><br />Quality, if the output power is greater than 20W+20W, heat sinks should be added<br /><br />12V&rarr;8&Omega;/10W+10W，4&Omega;/16W+16W<br /><br />16V &rarr; 8 &Omega;/15W+15W, 4 &Omega;/greater than 20W+20W<br /><br />20V &rarr; 8 &Omega;/20W+20W, 4 &Omega;/greater than 20W+20W<br /><br />24V &rarr; 8 &Omega;/30W+30W, 4 &Omega;/greater than 30W+30W<br /><br /><br /><br />Precautions for use:<br /><br />1. Use the amplifier board as far away from WIFI signals (router) as possible<br /><br />2. Recommended power supply voltage is DC 8-24V. If it exceeds 26V, the chip will burn out.<br /><br />3. When connected to a 4 &Omega; speaker, the power supply should not exceed 12V, and when connected to an 8 &Omega; speaker, the power supply should not exceed 24V<br /><br />4. The recommended power supply current is 2A or above.<br /><br />5. The working power of the module exceeds 20W * 2, and a heat sink needs to be added<br /><br />6. The horn cable should not be too long, ensuring it is suitable within 1 meter<br /><br />7. Pay attention to electrostatic protection. Before touching the power amplifier board, release the static electricity on your hands to avoid the chip from being broken down by static electricity. Bluetooth chips are sensitive to static electricity.<br /><br />8. Suggest adapting to speakers with a rated power of 30W or above to avoid overheating and burning of the speakers<br /><br /><br /><br />Package List:<br /><br />Amplifier board * 1<br /></p></div></div>
