The MXL 9000 Tube Condenser Microphone is a large-diaphragm, cardioid-pattern design based around a 12AT7 tube. The tube circuitry delivers a characteristic warm-yet-transparent midrange response that gives a smooth emphasis to both voices and instruments. It is housed in a silver-finished metal shell and comes complete with hi-isolation shock mount, power supply, and 7-pin power cable.Requires phantom power.
