Sm Pro AudioSM PRO Audio Tube Box preamplificatore valvolare formato API
TubeBox è un preamplificatore microfonico valvolare ad un canale in formato slot serie 500, caratterizzato da una elevata qualità sonora, design professionale e ad un prezzo vantaggioso. Questo piccolo ma potente dispositivo, è dotato di un preamplificatore valvolare in classe A, alimentazione phantom 48V, inversione di fase, pad -20 dB selezionabile, e un compressore ottico super veloce integrato. Il pannello frontale include inoltre un utile ingresso addizionale per microfono (jack da 1/4” TRS con phantom power selezionabile) – caratteristica normalmente non presente nei preamplificatori basati sul formato serie 500.
Il facile accesso alla valvola 12AX7, la rende sostituibile con altri modelli vintage o moderni, consentendo di personalizzare il suono e le performance di TubeBox a proprio piacimento. Il compressore ottico integrato dispone di controlli per la regolazione del rapporto di compressione, dell'attacco e del rilascio, e, la possibilità di utilizzare il VU meter intergrato per visualizzare il master level e il gain reduction. La qualità sonora del compressore integrato è garantita dall'amplificatore operazionale LME49720 che assicura una distorsione e una rumorosità estremamente bassa.
