The PowerTube is a 12AX7 equipped tube microphone preamp that delivers 140 Volts to the plate for optimal tube performance. The signal path begins with a convenient front-panel XLR for easy connection in any studio. A Jensen transformer coupled input produces the warm Bessel curve that has made Jensen a legend. The signal then passes through the tube-stage and 100% discrete class-A output stage to deliver over +65dB of gain. Separate trim and level controls make it easy to optimize signal to noise. Drive the PowerTube into the red for fun. A 10 segment LED bar graph delivers clear and precise monitoring. This is augmented with an Air EQ that adds presence to voice and a low-pass fi lter to eliminate unwanted low-frequency resonance. These features combine to make the PowerTube a spectacular choice for all microphones.
