Includes original Neumann wooden microphone case. New Neumann EA 87 shockmount is available separately.\u003cbr\u003e\u003cp\u003e\u003cspan class=\"maintext\"\u003eThe U87 was originally designed by Gerhart  Bore of Neumann as a solid-state replacement for the very successful U67  tube microphone, (somewhat ironically, the U87 was debuted in 1967).  The mic used the new K87 capsule, which was sonically identical to the  K67 capsule, but utilized phantom power instead of an external PSU. In  order to guarantee usability in the absence of a power source, the  microphone body was fitted with a pair of 22.5 V batteries to power the  mic.\u003c\/span\u003e  \u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e\u003cspan class=\"maintext\"\u003eBy 1986, when  phantom power had become an industry standard, there was no longer a  need for the battery compartment, and so the chamber was modified to  house a DC\/DC converter instead, and these mics are designated U87A. The  output of this version is 6dB higher, with a noise floor that is 4dB  lower than the original U87. Those models that had an XLR connector  instead of a Tuchel are designated U87 Ai.\u003c\/span\u003e\u003c\/p\u003e","brand":"Neumann","offers":[{"title":"Default Title","offer_id":44449592868967,"sku":"36217","price":2495.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_36217_1_d4c774e1-49fb-4802-ba84-d15fa26f1043.jpg?v=1787089604","url":"https:\/\/vintageking.mom\/products\/neumann-u87-ai-86448-used","provider":"Vintage King","version":"1.0","type":"link"}
