We Design The Sound

All The End working in pure Class A, without switches in AB or other classes, you always get the maximum coherence between the input signal and an output.

Another feature is the use of Current Amplification : the majority of amplifiers on the market using the variations of voltage at the output pin to create differences in the magnetic field in the coils of the speakers. But this is influenced by several aspects, as the change in impedance of the speakers as a function of frequency, temperature, parasitic resistance of cables and connections, and the tolerances of passive components used as filters. Using current control, with the slightest variation of the input signal corresponds to a proportional variation in the current on the voice coil, independent of all the factors listed above. This leads to an accuracy of reproduction impossible with other amplifiers.

Moreover, in the project have been removed all Condesa and the inductances in the signal path, not to have mismatches or mitigated. And you chose not to include any preamp stage, for not having any redundant circuit in the path of the signal that comes directly from the entrance on the transistor and then to the final output terminal.

The only negative notes from this project are the high consumption, about 18 A, compared to a sonic little more than a dozen watts, the dissipation of heat caused by the fact that even without input signal consumption remains constant and is dissipated into heat, and usually use the speakers with a sensitivity of 90 db, to enjoy the properties of this amplifier to a sound level fulfilling.
