The power supply interface is embedded in the reverse protection unit, reverse connection does not burn<br/>2. Output power depends on the power supply voltage and speaker impedance, high-power occasions recommended voltage 24v, current greater than 5A, try to use 4 ohm speakers, conducive to high-power<br/>3. The speakers must be boxed to use, bass recommended the use of finished boxes, homemade more complex and difficult to have good results, each channel, please strictly differentiate between positive and negative, connecting the reverse will seriously reduce the sound efficiency<br/>4. Speaker output for the BTL structure, it is strictly prohibited to use the common ground, otherwise the sound is not normal, may burn the amplifier<br/>5. Dual-channel support 4Ω50w and 8Ω30w speakers, bass support 2Ω100w speakers</div><br/><p>Parameter:<br/>Chip Type: TPA3116D2*2 <br/>Input Voltage: DC 8-24V <br/>Output Power: 50W*2+100W (Left/Right Channel + Bass Channel) <br/>Sound Channel: Dual Channel + Subwoofer <br/>Number of Channels: 2.1 Channels <br/>Output Impedance: 4-8Ω <br/>Frequency Response: 20Hz-20KHz <br/>Features: Power On Delay Anti-Shock <br/>Product Dimensions: 107*79*12mm <br/>Volume Adjustment: Knob Tuning clockwise volume + counterclockwise volume -</p><p>Bottom noise judgment method: input short-circuit, connected to the speaker to try to hear, normal should only be very weak noise (general distance from the speaker 50cm or so is not obvious) too large is not normal, if connected to the computer or cell phone noise increase indicates that the noise comes from the signal source!</p><p>Package include:<br/>Amplifier board*1 <br/>Kit*1<br/></p></div></div><br/>
