according to the function / application at its data sheet, this amplifier is more suitable room to room with hi-fi quality with enough power such as OCL. Aplikasinnya exist in high-end TV and surround sound. both worked in class AB. TDA7294 has been using a pair of mosfet as a final, while the LM3886 are still using ordinary transistors.
pretty good! using the tone control treble tones seem to be more powerful, less kicking bass tones can be overcome by the addition of tone control and super galaxy. a special, almost / no signal transient "bump" when power is turned on so it does not need additional protector speakers. The secret is in Resisror around 22k which is connected to pin 8 and Vee plus Elko capacitors valued 1-100uF. The default value is used to value 100uf/10V Elko. I suggest using a 220uF to increase the time delay so that the noise "bump" can dicut. should thus power amplifier. Using good quality component is an option. I think using standard components is also great, the important thing is the active component of IC, route the PCB's ground track, and wiring. There are two types, LM3886T and LM3886TF. I think the TF is more elegant black and easier installation because it does not need insulators. Remember the metal body is connected to the negative supply.
To drive a lot of speakers, these kits can we add to the power transistors such as the Sanken transistors. we can now own the circuit.
