The 4050 is the newest ribbon microphone that Coles have developed using the very latest magnet technology. The frequency response of the 4050 is exceptionally flat from 30 to 20,000 c/s and throughout this range the shape of the bi-directional (figure of eight) polar response is maintained substantially constant both in the horizontal and vertical planes. The 4050 is a versatile microphone and is ideally suited for many critical recording applications. Its smooth frequency response characteristics and ability to capture detail make it a fine choice for many instruments. There is also no discernible stray magnetic field and the 4050’s come with their own unique shock mount. The microphones can be easily rotated through 3600 making them very easy to mount in a "Blumlein" (crossed figure-of-eights) stereo configuration or any other configuration of choice. 

The 4050 microphones come in a foam lined rigid plastic carrying case with an adjustable universal stand mount and a soft cloth protective bag, for safe keeping.
