Il nuovo amplificatore Mosconi ad alta efficienza della serie Pico, si presenta con quattro canali di amplificazione con potenza di 90 Wrms  a 4 Ohm.

Stabile a 2 Ohm stereo e con  canali ponticellabili, dispone di ingressi ad alto e basso livello. lmpedenza d’ingresso (carico fittizio) e riferimenti di massa selezionabili tramite jumpers , crossover attivi commutabili.

Appositamente progettato per effettuare l’upgrade degli impianti di serie OEM. Con l’aggiunta del cavo segnale di collegamento EXT4LINK si interfaccia automaticamente al PIC0 8/12-DSP.

Già disponibile al prezzo di 389 Euro
