PreSonus Studio Channel

The Anywhere Channel.

The Studio Channel’s Class A tube preamplifier is based on our original BlueTube DP preamp and features a high-output 12AX7 tube that operates on voltages double that of other preamplifiers in its class. The result is lots of headroom and big tone. Gain and Tube Drive controls enable a wide range of sounds, from transparent and clear to edgy and overdriven.
