The CRM 202-RF is a dual boundary layer through table cardioid condenser microphone, with a built-in
mechanism that will allow the user to make the microphone disappear without having to physically
remove it from the table. This is achieved by simply pressing the top of the microphone downwards
until it locks; then by pressing the microphone again it will raise itself back to its original position

above the surface of the table. Engineered in high quality brass with built in shock mount and RF filter.
