I have two of these microphones for stereo recording . I run them into a focusrite isa preamp and they sound very impressive. These microphones have a multi polar patterns which gives you a lot of flexibility in the recording process. They have a have a large full bodied sound that sounds expensive. These microphones run on phantom power from your mic preamp or mixing desk. They work well in the studio as a good flexible microphone for vocal and instrumental work and work well as a stereo pair.
