The JM37 is a microphone in the tradition of classic studio microphones. It is a large sized diaphragm true capacitor microphone with a fixed Cardioid head (JM37-DP is Dual Pattern: Omni and Cardioid). This feeds the FET type pre amplifier for low noise. The output balancing is handled by a solid state FET output.
The capacitor element is manufactured to the classic 'con-centric electrode' design, which provides smooth extended frequency response. Quality is further enhanced by utilizing dynamic feedback at the capacitor element. This original tech-nique eliminates distortion, which can occur when using this type of microphone at high volume levels.
The capacitor membrane is micro fine Mylar with gold sputtering, voltage polarized by phantom power. The microphone body is made of machined brass; Connection is via screened balanced audio cable with 3 pin XLR connectors.
