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.\u003c\/p\u003e\u003cp\u003eThree 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.\u003c\/p\u003e\u003cp\u003eThe unusual shape of the microphone's body is especially designed to minimize undesirable reflections of sound toward the pickup element.\u003c\/p\u003e\u003cp\u003eAcoustic 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.\u003c\/p\u003e\u003cp\u003eThe 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 tailored to a wide variety of applications. For example, the microphone can be used as an overall pickup for a large orchestra or it can be used as a solo or spot mike for individual instruments. It may also serve as an announce microphone where its proximity effect may be desirable.\u003c\/p\u003e\u003cp\u003eThe direction of maximum sensitivity is radial to the microphone body, i.e. side addressed. The front of the microphone is indicated by the model number and the pattern selector switch.\u003c\/p\u003e\u003cp\u003eThe pick-up capsule is mounted in a large, acoustically open headgrill which prevents mechanical vibration interference. This gives the microphone a clean, colorless sound characteristic.\u003c\/p\u003e\u003cp\u003eThe internal vacuum tube amplifier of the UM 900 can be powered by any external 48 volt phantom supply which can provide at least 4 mA of current.The amplifier uses a specially selected vacuum tube.An internal transverter provides all the necessary voltages.The low impedance output is implemented with an operationalamplifier and balanced output transformer.\u003c\/p\u003e\u003cp\u003eThe UM 900 can be connected with a cable of up to 150 m length without any effect on sound quality.\u003c\/p\u003e","brand":"Microtech Gefell","offers":[{"title":"Default Title","offer_id":44449932116071,"sku":"57838","price":4222.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/gefell-um-900-nickel-1_4c84e781-5541-4637-ab18-c13536516f6f.jpg?v=1787091003","url":"https:\/\/vintageking.com\/products\/gefell-um-900-satin-nickel","provider":"Vintage King","version":"1.0","type":"link"}
