Amplifier Board, DROK TPA3116 HiFi Dual-Channel Stereo Audio Amplifier Subwoofer DC 10-25V Digital 2.0 Amp Module 25W+25W Output with Volume Knob

Parameters:<br /> Voltage range: DC 10-25V<br /> Output power: 50W (Max)<br /> Output load: 4-8 Ohm (Recommend)<br /> Frequency response range: 14-100KHz<br /> Signal-to-noise ratio (SNR): not less than 100DB<br /> Switching frequency: 1.2MHz<br /> Reverse connection protection: Yes (Positive and negative reversal is not energized.)<br /> Quantity of channels: one left channel and one right channel<br /> <br /> Use Notes:<br /> 1. The speaker of each channel must be connected in strict accordance with the wiring diagram. If reverse the connection, will seriously reduce the sound efficiency.<br /> 2. The current ability of external power supply 5V port is within the limits of 100mA. Super-power use is strictly prohibited.<br /> 3. Increasing the power supply voltage appropriately and using relatively low impedance speakers, can be very effective to improve the output power.<br /> 4. We recommend for adequate power supply (the current must be large enough), otherwise it cannot give play to the power of amplifier and speaker.<br /> <p> 5. Although the product is a digital amplifier, but there still will be heating phenomenon during the use, it is normal. </p> <p> <br /> </p> Package Includes:<br /> 1 × TPA3116 Amplifier Board<br />
