Mosconi Pico 4 sa

The Mosconi PICO 4 SA is a powerful and exceptionally compact 4-channel power amplifier featuring modern Class D technology, designed specifically for semi-active operation of loudspeaker systems. Despite its small size, it impresses with high output power, outstanding efficiency, and versatile connectivity options.

The integrated semi-active crossover allows for separate control of different speaker sections. With high-pass and low-pass filters set at 280 Hz and 220 Hz, respectively, the PICO 4 SA is particularly well-suited for semi-active front systems, such as those with separately driven woofers and midrange/tweeter units.

Thanks to its high-level and low-level inputs, the amplifier can be integrated into both existing factory systems and high-quality aftermarket systems. The automatic power-on function via the high-level signal makes it easy to integrate into vehicles with factory-installed radios.

The bridgeable output channels, 2-ohm stability, and compact design allow for flexible installation even in tight spaces.
