Product Description

DIY Kit- 2.1 STA540 subwoofer 3-Channel power amplifier DIY Kits (NE5532 preamplifier)

Product Introduction:

• This is a subwoofer 2.1 3-Channel power amplifier board DIY kit, this kit adopts Original ST TDA540 audio amplifier IC,2 pcs American TI NE5532 as preamplifier & Bass processing integrated IC, the overall sound effects is deep & powerful,alt is clear.
• The maximum output for L/R channel is 2*13W, the Maximum output for Subwoofer is 38W. 
• Single Power Supply.
• Suggest power supply:
  Voltage:AC 10~18V or DC9~14V Current :3A or above, the sound effects will be better.
• Two potentiometers are bass control & Total volume Control.
   This circuit is not the same as traditional circuit which adopts RC to control Bass/Treble via potentiometers, its Bass circuit adopts Low Pass Filter,doesn't need additional Treble potentiometer, so it is quite suitable to be used for the power supply refitting for automobile, motorcycle, electric vehicles and multimedia audios, it can help a lot for promoting your sound quality.
• R/L Channel can be connected with 2Ω~4Ω~6Ω~8Ω Speakers,subwoofer can be connected with 4Ω~8Ω speaker.
• This kit shares the same PCB board with TDA7377 2.1 amplifier kit, when in use, the difference is range of input voltage.

• The PCB of this kit adopts good quality double-side glass fiber Board,high-level red oil solder mask layer,reasonable layout & beautiful &generous. Less peripheral components, no noise & simple Peripheral design,quite suitable for DIY triers!

        PCB Size:90mm*50mm(L X W)
