<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features:<br/>1. Adopting PAM8403 chip, it is a 3-watt Class D audio power amplifier with the characteristics of low harmonic distortion and low noise crosstalk. <br/>2. This dual channel digital amplifier board uses 3P audio terminal input with an input voltage of DC5V. <br/>3. Onboard 50K volume adjustment relay, which can be used to turn on and off the power of the amplifier, as well as freely adjust the volume. <br/>4. This amplifier also has dual channel audio output, with a power of 2 * 3W, and can be directly paired with low-power office speakers. <br/>5. This model uses high-quality components to achieve good sound quality for sound playback; At the same time, it is much more efficient than Class A amplifiers, which extends the battery life and is an ideal choice for portable devices. <br/>6. The onboard volume potentiometer, onboard switch, and volume adjustment potentiometer can freely adjust the volume level and switch the power supply. Rotate clockwise to turn on the power, increase the volume, rotate counterclockwise to decrease the volume, and turn off the power.</p><p>Parameter: <br/>Product Name: Dual Channel Digital Amplifier <br/>Input voltage: DC5V <br/>Audio input: 3P terminal <br/>Number of channels: Dual channel <br/>Output power: 2 * 3W <br/>Appearance size: 38 * 22 * 13mm</p><p>Package include:<br/>1* module <br/>3 * rays<br/><br/></p></div></div><p><br/></p>
