The KM 254 is the cardioid version of Neumann's legendary KM 250 series, prized for its articulate, extended high frequency response and remarkably low noise floor. These mics were the go-to choice for classical recording engineers throughout the 1970s and beyond, and they remain exceptional on acoustic instruments, piano, strings, woodwinds, and room mics.\u003c\/p\u003e\u003cp\u003eThis example is in excellent condition and comes complete with its original power supply, cable, and transit case.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Small diaphragm transformerless condenser\u003c\/li\u003e\n\u003cli\u003ePolar pattern: Cardioid\u003c\/li\u003e\n\u003cli\u003eSerial: 519\u003c\/li\u003e\n\u003cli\u003eManufacturer: Neumann\u003c\/li\u003e\n\u003cli\u003eCondition: Excellent original\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eContact us with any questions about this piece.\u003c\/p\u003e","brand":"Neumann","offers":[{"title":"Default Title","offer_id":67655864451378,"sku":null,"price":5500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/6892\/6514\/files\/Photo_Apr_17_2026_11_39_24_AM_d9142f23-e9ec-4759-8415-02f1bad3b230.jpg?v=1790465397","url":"https:\/\/sphererecordingconsoles.com\/products\/neumann-km-254-small-diaphragm-condenser-microphone","provider":"Sphere Recording Consoles","version":"1.0","type":"link"}
