Mercenary Audio - Microtech Gefell UM 900 "The Phantom"

The world's only phantom powered tube microphone!! Using some remarkable technology the wizards at Microtech Gefell not only figured out how to power a tube with 48v phantom power but also how to charge a gold sputtered PVC diaphragm. Back in the day when Neumann mics were made by the same company that is now Microtech Gefell, PVC was the material from which the original U-47 and M-49 diaphragms were built. Fast forward a half a dozen decades and you now have what will be known as the classic mic of the early 21st century... even beyond the "trechic" art deco styling, the UM-900 is one of the most special sounding chic" art deco styling, the UM-900 is one of the most special sounding microphones in production today... the perfect blend between new and old.

gefell um900 features

The UM 900 is the first switchable pattern, valve condenser microphone which can be connected to industry standard 48 volt phantom powering using a normal 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.

Three switches are located around the body of the UM 900. The switch in the front selects the polar pattern: omni, wide cardioid, cardioid, hyper cardioid and figure 8. Located 120 degrees to each side are switches for gain adjust and low frequency roll-off.

The unusual shape of the microphone's body is especially designed to minimize undesirable reflections of sound toward the pickup element.

Acoustic influences which could result from the housing resonance and/or mechanical vibration are reduced by the robust construction and by a special fixture within the microphone's housing which dampens vibration.
