Product Description
The PreSonus TubePre V2 is a top - notch used tube preamplifier and DI box that looks like new. It's an open - box product with no signs of use. PreSonus has a long - standing reputation for designing high - quality preamps, always putting audio quality first. When upgrading the popular TubePre V2, they improved the already great sound without increasing the price. It's a fully professional tube preamp with a dual - servo gain stage. This allows you to boost the program signal to high levels while keeping background noise in check. Discrete components and high - voltage operation give it better dynamic range and more detail than other single - channel tube preamps in its class. The TubePre V2 offers a wider range of sound options and more focused tube saturation compared to the original. It uses PreSonus' well - known XMAX Class A solid - state preamp, followed by a 12AX7 vacuum - tube stage in the signal path. You can adjust the Drive saturation control to add different 'colors' of sound, from gentle warmth to total fuzz. Key features include an XMAX Class A preamp input stage, a 12AX7 dual - servo vacuum tube output stage, Input Gain control, 48V phantom power, an 80 Hz high - pass filter, a - 20 dB pad, instrument input select, a polarity - reverse switch, a backlit VU meter, a Clip LED, various input and output connectors, a compact 1/3U rack - mount chassis, and an external 12 VDC, 1A power supply. Technical specs cover details such as mic input, instrument input, analog output, tube stage, power, and physical dimensions.
Using the PreSonus TubePre V2 is easy. First, connect your instrument or microphone to the appropriate input. For a microphone, use the balanced XLR input, and for an instrument, use the unbalanced ¼” input. Then, turn on the power using the external 12 VDC, 1A power supply. You can adjust the Input Gain control to set the right level for your signal. If you're using a microphone that needs phantom power, turn on the 48V phantom power switch. The TubePre V2 also has an 80 Hz high - pass filter that you can use to cut out low - frequency noise. You can twist the Drive saturation control to add different tones to your sound. When it comes to the output, you can choose between the balanced XLR line output or the unbalanced ¼” line output. Here are some things to keep in mind. Make sure to use the correct power supply to avoid damaging the unit. Don't overload the input by setting the gain too high, as this can cause distortion. Also, be careful when handling the 12AX7 vacuum tube as it can be fragile. For maintenance, keep the unit clean by using a soft, dry cloth to wipe it. If you're not using it for a long time, store it in a cool, dry place. And remember, if you have any questions or problems, you can always refer to the user manual or contact PreSonus support.
