The TDA7294 power amplifier is intended for the use of subwoofer speakers because the amplifier with the TDA7294 chip is equipped with a subwoofer preamp, there are also frequency and phase settings so we can add or reduce the output frequency as we wish, and for the phase, we can set from 0-180 level. For[…]

Hello friends, in this Post I will assemble a class AB AX-BLAME 700 power amplifier, this is the PCB, this PCB layout is designed by my friend Hamas shofwanudin, this cool design uses arc routing angle and there are some that use  45 degrees angle trace. It also uses 2 layers top and bottom copper.[…]

This High Power Amplifier circuit is a class D power amplifier, which has high enough power to generate 300W of power at 8 Ohm – and also more power up to 500W at 4 Ohm. This Power Amplifier can generate great power if given enough power supply. For example, you can use a 30A transformer[…]

Hello friends in this post elcircuit will share a very simple tone control layout which was designed by ELECTROINDIA Youtube channel, using only 2 transistors as an amplifier, This tone control has bass, treble and volume settings. and using a 12VDC power supply voltage. following the PCB layout, you can download the complete pdf format[…]

Hello friends, on this occasion I will post again, the discrete class-D amplifier UcD Superlite, Class-D Discrete Amplifier UcD Superlite with RM Core Is that a discrete class-d UcD? UCD is one of the Class D Topologies patented by Philips (NXP) and this Class D type is widely used in Hypex products which they claim[…]

Hello friends, in this post I will share a little about Class-T power amplifiers, this Class-T power amplifier is as reinforcing as Class D power amplifiers that use switching modulation, combined with proprietary techniques by the Tripath manufacturer, where there is the difference in control time and switching frequency depends on the input signal and[…]
