AIYIMA TPA3116 Dual-channel Stereo High Power Digital Audio Power Amplifier Board TPA3116D2 Amplifiers 2*120W Amplificador DIY
Super fast delivery-11 days, packed well, all finished whole. The fact that under the radiator there will be no thermal paste was ready, but that when the amplifier is turned on, the hf noise in the speakers was not ready. Max. Power was achieved at the initial position of the adjustment resistors. It's all about overestimated coef. Amplification-36 db and the use of a pre-amplifier. If you remove the radiator and solder the r3 resistor at 75 kohm, the rf noise disappears and the underline resistors are already moving into the middle position. At power 19 v, the sine wave restriction is already higher than 13 v, which makes the power not more than 13*13/4 = 42 watts. A little later i will check at 24 v power.
Fast ship, nice quality package, and good sound.
Thank you very much.
It came quickly, the fee works. The quality of questions is of course, but the price is respectively cheap. In the columns there is a buzzing and extraneous noise. The speakers themselves with a nominal value of 30 W, the underline resistor with a stroke of 180 degrees set to a maximum of 3 degrees, the amplifier can not cope even under such circumstances. But in general, loud enough and so. So for their money, the fee is exported normally.

58% buyers are happy with:Sound good. Delivery-11 fast. Fee works. Db amplification-36. Power was achieved. Ship fast. Quality package nice. It came quickly. Quality of questions is of course. Parcel came quickly.
33% buyers complain about:Amplifier is turned on. Rf noise disappears. Sine wave restriction is already higher than 13 v. Noise extraneous. The amplifier visually has not yet failed. Clicks pre-amplifier sound. It's all about overestimated coef.
