MAESTRO Reference Bloc

The basic structure of the amplifier Maestro MONOBLOCK is the same used in the precision balanced amplifier used in the laboratories. It is made of three different amplifiers. The first two must amplify in tension the balanced signal and the third one must supply the necessary current amplification to drive the speakers. This kind of structure has two important benefits: the first one is a high immunity to the disturbs, while the second one is the possibility to improve each amplification stage. The separation between the gain in tension and of the gain in current permits to realize class A tension amplifiers made with low power components, so to obtain a frequency response up to about 500kHz. Such frequency extention gives the possibility to mantain the phase errors to a very low level. The power section has been designed to obtain a high gain in current and not in tension. Thanks to this solution, it is possible to keep the frequency response at full power around at 200kHz. Also the bass frequency extention has been realised with care applying an off-set recover circuit able to go down to 3Hz. Due to its two stages configuration, the amplifier Maestro Monoblock does not have a global feedback between inputs and outputs.
