It uses a custom all-brass CK12-style capsule, a JJ 12AY7 vacuum tube, and a CineMag USA output transformer paired with WIMA, Solen, and polystyrene capacitors. Three polar patterns are selectable from the external power supply. The WA-251 is known for its controlled bass (with a built-in roll-off below 50 Hz), present midrange, and a smooth 5-10 kHz dip in cardioid mode that tames harshness on vocals, acoustic guitars, and other acoustic sources.\u003c\/p\u003e\n\u003cp\u003eThe built-in 50 Hz high-pass characteristic keeps the WA-251's low end tight in the mix rather than muddy or boomy. With most usable bass frequencies running from 60 to 250 Hz, the WA-251 captures lows and mids with definition. In cardioid mode, the 5-10 kHz dip smooths out the high end, making it forgiving on sibilant vocalists and bright acoustic instruments. This frequency shaping is inherent to the capsule and circuit design, not a switchable filter, giving the WA-251 its signature sound from the moment it is plugged in.\u003c\/p\u003e\n\u003cp\u003eThe CK12-style capsule, JJ 12AY7 tube, and CineMag USA transformer work together to deliver the warm, balanced tone that made the original 251-style microphone one of the most sought-after studio tools ever produced. Three polar patterns (cardioid, omnidirectional, and figure-8) provide flexibility for different recording setups and room acoustics.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Tube condenser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapsule:\u003c\/strong\u003e WA-12-B-60V, edge-terminated, dual-backplate, all-brass CK12-style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube:\u003c\/strong\u003e JJ Slovak 12AY7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransformer:\u003c\/strong\u003e CineMag USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolar patterns:\u003c\/strong\u003e Cardioid, omnidirectional, figure-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 20 Hz to 20 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax SPL:\u003c\/strong\u003e 132 dB (\u0026lt;0.5% THD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput impedance:\u003c\/strong\u003e 200 Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-noise:\u003c\/strong\u003e 12 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eS\/N ratio:\u003c\/strong\u003e 80 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic range:\u003c\/strong\u003e 125 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable:\u003c\/strong\u003e Gotham 5 m GAC-7, 7-pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMic dimensions:\u003c\/strong\u003e 247 x 46 mm (9.72\" x 1.81\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal weight:\u003c\/strong\u003e 5.44 kg (12 lb) including PSU, shockmount, and cables\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWA-251 microphone\u003c\/li\u003e\n\u003cli\u003eExternal power supply with IEC cable\u003c\/li\u003e\n\u003cli\u003eShockmount\u003c\/li\u003e\n\u003cli\u003eGotham 5 m 7-pin GAC-7 cable\u003c\/li\u003e\n\u003cli\u003eWood storage box\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Warm Audio","offers":[{"title":"Default Title","offer_id":50525585441017,"sku":"WA251-b1","price":1329.05,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/WA251.jpg?v=1765322114","url":"https:\/\/blackoutaudio.com\/products\/warm-audio-wa251-b1","provider":"Blackout Audio","version":"1.0","type":"link"}
