    Direi che se la cava molto bene. E' necessario tagliare il sub con un semplice crossover anche passivo. Non c'è molto rumore di fondo. Ha un solo ingresso, peccato. Direi obbligatorio alimentarlo con 24V - 3>5Ah per avere una qualità del suono decisamente migliore. Consigliabili altoparlanti sopra i 50W per non distruggerli! Ho acquistato questa scheda per sostituirla a quella presente qui: https://www.amazon.it/gp/product/B01HT2EB74/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 , visto che il modulo bluetooth implementato nella scheda interna creava solo disturbi al suono NON INDIFFERENTI

    piccolo ma grande amplificatore, è possibile costruire un sistema con sub woofer con pochi soldi e dalla grande dinamica. Può essere il cuore di un impianto di grande impatto ed economicissimo anche nei consumi. Secondo me questo ampli lillipuziano di classe d non scalda ma è incredibilmente ben suonante rapportato al prezzo, il dettaglio è stupefacente, se usato con casse adeguate, insomma: Grazie Amazon, l'ennesimo buon prodotto! Ps.: il prodotto è indirizzato a chi già è capace di montare componenti elettronici, quindi vanno saldati i fili delle casse, mancano anche le istruzioni, il jack dell'alimentazione ha il positivo centrale, il led spia si accende appena si alimenta e l'interruttore è solo per evitare il tansiente d'accensione.Vanno aggiunte anche le manopole da prendere a parte.
