Совсем крохотный усилок, думал будет больше. Получил в сентябре 2013 года, закинул в ящик и всё никак до него не добирался, а тут в июне 2014 года все же до него добрался, и был удивлён, от блока питания (зарядка от телефона) работает на ура, звук громкий, что удивило. Качество звука обычное нормальное. Но на самой плате неправильно расставлена полярность на выходе звука, там где стоит "+" должен быть "-" и так на двух каналах. Из за чего сначала подумал, что бракованный, т.к. не было звука на одном канале (подключал через провод с 3-ми жилами), но поменял полярность и все заработало.

Il circuitino è piccolo, piccolo. Il potenziometro dispone dell'interruttore di accensione.
Funziona molto bene, di potenza ridotta e qualità audio discreta (niente HiFi). Ho provato a pilotare due diffusori da pavimento con woofer da 12" (30 cm) ed è riuscito a fornire un discreto volume senza distorcere in modo apprezzabile. A questo prezzo non si può pretendere di più.
Ordinato con consegna economica, e di piccola cifra per evitare i balzelli doganali.
