The CRM 203-RF is a tri-element boundary layer through table 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 unl it locks; then by pressing the microphone again it will raise itself
back to its original posion above the surface of the table. Engineered in high quality brass with built in shock mount and RF
lter.
