ปรีแอมป์พร้อม Di แบบหลอด PreSonus TubePre V2 Single-channel Microphone and Instrument Preamplifier with Built-in Tube Tone Circuit, 12AX7 Vacuum-Tube Stage, Balanced and Unbalanced I/O, Phantom Power, High-Pass Filter, Phase Reverse, Backlit VU Meter
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.
