Microtech Gefell UM 900 | Dark Bronze

Microtech Gefell UM 900 

The UM 900 is the first switchable pattern, tube condenser microphone that can be connected to industry standard 48 Volt phantom powering using a regular 3-pin XLR-microphone cable. This is made possible by an advanced circuit design for the amplifier and internal power supply. The pickup capsule uses a traditional, proven design with two large, gold plated plastic membranes.

The high sensitivity and low noise of the UM 900 make it especially suitable for vocal and speech pickup in professional sound recording studios, scoring stages and broadcast studios. The 5 pickup patterns allow the microphone to be used for a wide variety of applications. E.g. the microphone can be used as an overall pickup for a large orchestra or as a solo or spot mike for individual instruments. It can also be used as an announcers microphone where its proximity effect is desirable.
