Mosconi Pico 4|8 DSP – 4-kanaals versterker met DSP

Special features
Signal controlled power supply

In contrast to Class G/H, the power supply is only switched on when required (high levels) and regulated depending on the power requirement. Benefit: The quiescent current is between 250mA and 450mA (depending on the speaker wiring) -> Particularly interesting for electromobility and mobile homes

Converterless high-speed PWM power amplifiers

Highly efficient PWM output stages with currently the fastest carrier frequency worldwide (>2MHz), enables HiRes audio transmission and the extremely small size. The modulation takes place without a DAC directly from the 96kHz TDM signal of the DSP, which means that the background noise is close to zero and THD+N ~0.02% / 1W.
