Description
PreSonus TubePre v2 microphone preamplifier offers an even wider palette of sound options and a much more focused tube saturation than the TubePre mic preamp. It has been upgraded to employ PreSonus’ popular XMAX Class A solid-state preamp, which is followed in the signal path by a 12AX7 vacuum-tube stage. Twist the TubePre v2 Drive saturation control to add the “color” that only a hand-selected 12AX7 vacuum tube can deliver from gentle warmth to total fuzz.
Housed in a rugged case, the rear panel of the TubePre v2 sports separate unbalanced, ¼” instrument and balanced, XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. All of the extras you need for professional operation include a high-pass filter, phantom power for condenser mics, polarity reverse switch and a backlit VU meter.
More than a mic preamp, the TuebPre v2 serves as a direct box (DI) for guitars and basses alike thanks to its separate instrument and mic inputs, and it’s small enough to carry almost anywhere.
