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.<\/p>\n

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.<\/p>\n
