Amp Class D / T based on an integrated TDA7492 ST Microelectronic. (Look the datasheet TDA 7492 the net to get an idea of what happens is done)
Bluffing product report reproduced on size and power consumption.
The quality is there if we stay below 20W, beyond this it spoils significantly.
Without going into esoteric considerations this amp does its job according to my measurements with generator & digital oscilloscope. (FFT even without big disappointment in odd harmonics)
But to stay in the nails must be very careful limpédance ups connected speakers. If the agreement is not correct, the low pass filter (self & output capacitor) can not effectively eliminate the modulation carrier to 305KHz transforming into beautiful Lampl AM transmitter with carrier walking in the speaker cables
This amp is designed with an active filter for an impedance of 8 Ohms.
