PreSonus TubePre V2 Microphone Preamp

Full Description

Clean and Accurate Sound from Preamps

PreSonus? popular Class A XMAX preamps are widely lauded for their clarity and transparency. Housed in a rugged, 1/3-rackspace case, the TubePre V2 rear panel sports separate unbalanced, ¼" instrument and balanced, XLR mic inputs and unbalanced ¼" and balanced XLR line outputs. The front panel offers controls for gain, 48V phantom power, 80 Hz high-pass filter, and polarity-reverse, as well as a mic/instrument input switch. A lighted VU meter and a clip LED help you keep an eye on your levels.

VU Meter

Each channel has an illuminated VU meter so you can visually monitor your input levels. A Tube Drive control provides a wide range of sounds: when it is clicked off, you are using the solid-state preamp for quiet, transparent amplification; when it is engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.
