PreSonus has a long - standing reputation for designing top - notch preamps, always prioritizing audio quality. When upgrading the popular TubePre V2, we aimed to enhance its already excellent sound without hiking the price. The new TubePre V2 is a fully professional tube preamp, just like its predecessor. It features a dual - servo (capacitor - free) gain stage, enabling you to boost the program signal to high levels while keeping background noise in check. With discrete components and high - voltage operation, it offers a dynamic range and detail that outshines other single - channel tube preamps in its class. The TubePre V2 takes sound options to a new level compared to the original. It now uses PreSonus’ well - loved XMAX Class A solid - state preamp, followed by a 12AX7 vacuum - tube stage in the signal path. Turn the TubePre V2 Drive saturation control, and you can add a wide range of 'colors' to your sound, from gentle warmth to complete fuzz, thanks to the hand - selected 12AX7 vacuum tube. Key Features: XMAX Class A preamp input stage, 12AX7 dual - servo vacuum tube output stage, Input Gain control, 48V phantom power, 80 Hz high - pass filter, - 20 dB pad, Instrument input select, Polarity - reverse switch, Backlit VU meter, Clip LED, 1 unbalanced ¼” instrument input, 1 balanced XLR mic input, 1 unbalanced ¼” line output, 1 balanced XLR line output, Compact 1/3U rack - mount chassis, External 12 VDC, 1A power supply. Technical Specs cover mic input, instrument input, analog output, tube stage, power, and physical dimensions details.
Using the PreSonus TubePre V2 is straightforward. First, connect your audio source. You can use the balanced XLR mic input for microphones or the unbalanced ¼” instrument input for instruments. Make sure to set the Input Gain control according to the strength of your input signal. If you're using a microphone that requires it, turn on the 48V phantom power. The 80 Hz high - pass filter can be handy to reduce low - frequency noise like hum. The - 20 dB pad is useful when you have a very strong input signal. You can select the instrument input if needed and use the polarity - reverse switch to adjust the phase. Twist the TubePre V2 Drive saturation control to add that unique tube 'color' to your sound. Keep an eye on the backlit VU meter and Clip LED to avoid over - driving the signal. For power, use the external 12 VDC, 1A power supply. When it comes to maintenance, keep the unit clean and free of dust. If you're not using it for a long time, store it in a dry place. Avoid exposing it to extreme temperatures or humidity. And if you ever need to replace the 12AX7 tube, make sure to follow the proper procedures and use a compatible tube.
