The TubePre V2 from PreSonus is a fully professional tube preamp with a dual-servo (no capacitors) gain stage that allows for boosting the program signal to high levels without significantly increasing the background noise. Discrete components and high-voltage operation provide wide dynamic range without sacrificing detail. The preamp also serves as a direct box (DI) for guitars and basses and it's small enough to carry almost anywhere.

Housed in a rugged case, the unit features an XMAX Class A solid-state preamp followed in the signal path by a 12AX7 vacuum-tube output stage. Also included are high-pass filter, phantom power for condenser microphones, a phase reverse switch, and a backlit VU meter. The rear panel contains an unbalanced 1/4" instrument and a balanced XLR microphone input, along with unbalanced 1/4" and balanced XLR line outputs.

        Comments about PreSonus TubePre v2 - Tube Preamplifier/DI Box:

        Got this to use as a (cheap) mic pre for a DAW. I don't often do audio, mostly use it for recording scratch track VO. Does the job, and certainly good for the price. Hard to get enough gain without adding a little distortion though. Fairly quiet, and for about one c-note, can't complain. After using it for 6 months, I'm looking to upgrade to a better channel strip for a cleaner sound.

            I got this to pre-amplifiy wireless microphones into an amp using 1/4" inputs. IT woked perfect but amazinegly it gave a nice tonal to the voice sound making the sound very beatiful.
