PreSonus' popular Class A XMAX preamps are widely lauded for their clarity and transparency. Our tube preamps are beloved for their warm, smooth sound. With the Blue Tube DP V2 dual-path mic/instrument preamp, you get both types of high-quality sound in one unit.
No wonder the original BlueTube DP became a classic!
Now we've improved on the classic unit with the BlueTube DP V2. The solid-state path now feeds PreSonus' top-of-the-line Class A XMAXTM mic preamplifier with 80 dB of variable gain-an upgrade from the original BlueTube DP's solid-state stage.
