Presonus TubePre V2 Mono Tube Preamp (1/3U)

Presonus TubePre V2 Mono Tube Preamp (1/3U)     

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

Comes in a rugged case, the unit is featured with an XMAX Class A solid-state preamp followed in the signal path by a 12AX7 vacuum tube output stage. Also, high-pass filter, phantom power for condenser microphones, a phase reverse switch, and a backlit VU meter are also included. 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.
