The UA-S610 SOLO/610 classic vacuum tube mic preamp and D.I. box by Universal Audio is designed to deliver the classic sound of the Putnam 610 console. The all-tube SOLO/610 provides the silky vintage warmth of the original UA 610 console used by artists ranging from Sinatra to Van Halen. Its all-tube circuit was carefully created to maintain the character of its vintage predecessor with the audiophile components and solid build you'd expect from a UA product. It also has mic and D.I. inputs; Thru output; continuous gain and level controls; a gain-structuring Shape switch; 48V phantom power; Lo Cut filter; phase reverse; ground lift; and versatile mic/line level output switch. The SOLO/110 is hand assembled by Universal Audio in the USA.
