This is a DIY Kit ONLY! You need to solder it all by yourself!

If you do nt want to solder it,you can buy a finished board in our store!

      Product Introduction:

  • This is a subwoofer 1.0 power amplifier board DIY kit, this kit adopts Original ST TDA7294 audio amplifier IC,American TI NE5532 as low frequency processing integrated IC, the maximum output for the circuit can up to 100W. Reasonable pCB layout,no noise,high Performance-to-Price Ratio.
  • The bass output frequency of this circuit can be adjusted according to DIY fans' taste,the frequency of their current speakers or the requirements of the Speaker volume.Just only change the capacity of the C5* capacitor can change the output frequency, the capacity of C5* capacitor can be 102,103,223,323,473,683 or 104.If you want full frequency output, just remove the C5* capacitor will be OK.
    (If you want even lower frequency output, you can change C4 capacitor from 224 to 474,R10 resistor from 22K to 47K.Only if your speaker can bear this frequency, or it will bring cracking noise for the low frequency pulse.)
  • Humanized design,compact size, can be used flexiable in wide range.You can single use it as a 1.0 power amplifier, or use two of them as a high power 2.0 amplifier, and also you can use it to upgrade your current 2.0 amplifier to a 2.1 sbuwoofer power amplifier.
  • Power supply Requirements:
    Voltage:Dual AC 11~25V or <=+/-DC35V (When use dual DC power supply, use the (V+ GND V-)3 line output DC power.Can not use the single power supply(such as the Notebook power supply.)
    The ouput of the power supply:50W or above.The larger of the power supply input, the larger the amplifier output, also the larger heatsink it needs.

   Notes:

   When connecting the dual transformer input, be sure to connect the 3 line correctly or it will damage the IC when electric the circuit.
