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

Amplifier Board, DROK TPA3116 HiFi Dual-Channel Stereo Audio

Parameters: Voltage range: DC 10-25V Output power: 50W (Max) Output load: 4-8 Ohm (Recommend) Frequency response range: 14-100KHz Signal-to-noise ratio (SNR): not less than 100DB Switching frequency: 1.2MHz Reverse connection protection: Yes (Positive and negative reversal is not energized.) Quantity of channels: one left channel and one right channel Use Notes: 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. 2. The current ability of external power supply 5V port is within the limits of 100mA. Super-power use is strictly prohibited. 3. Increasing the power supply voltage appropriately and using relatively low impedance speakers, can be very effective to improve the output power. 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. 5. Although the product is a digital amplifier, but there still will be heating phenomenon during the use, it is normal. Package Includes: 1 × TPA3116 Amplifier Board
