C-valve

Tube Microphone Preamp

Adds the warmth of analog tubes to digital recordings.

A true tube pre-amp that provides pure signal and silky sound. It features variable gain and variable tube process saturation for adding harmonics. Regardless of which mic you use, it will maintain detail and transparency. 48-Volt phantom power, phase and peak limiter round out the control set. A large analog VU output meter and a 6-segment LED input meter make it easy to adjust the gain. Use its insert points along with a C Class Compressor for a direct path to a gorgeous front end sound. The C-valve provides a digital output as well.
