Built around a socketed X731 discrete op-amp (a reproduction of the classic Melcor 1731), the WA12 MKII delivers the punchy, focused tone of iconic American console preamps with output attenuation control for driving the signal path into musical saturation.\u003c\/p\u003e\n\u003ch3\u003eOp-Amp and Tone Shaping\u003c\/h3\u003e\n\u003cp\u003eThe X731 discrete op-amp is the warmer predecessor to the modern 2520-style design, delivering clean and lifelike tones at moderate gain and harmonically rich saturation at higher settings. The op-amp is socketed using the standard 6-pin 2520 footprint, allowing replacement with any compatible discrete op-amp for different tonal character. The Tone switch toggles input transformer impedance from 600 to 150 Ohms, adding top-end air and sheen particularly suited to ribbon and darker dynamic microphones. The output attenuation control sits after the CineMag output transformer, enabling the preamp and transformers to be driven into saturation while managing the level hitting the converter.\u003c\/p\u003e\n\n\u003ch3\u003eConnectivity\u003c\/h3\u003e\n\u003cp\u003eA front-panel 2 MOhm true Hi-Z input routes instrument signals through the full discrete signal path, including both CineMag transformers and the X731 op-amp. The rear XLR mic input, balanced XLR and TRS outputs, switchable 48V phantom power, -20 dB pad, and polarity inversion handle standard studio recording needs in a compact half-rack desktop format.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Single-channel microphone\/instrument preamplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTopology:\u003c\/strong\u003e Fully discrete, high-voltage, dual-transformer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOp-amp:\u003c\/strong\u003e X731 discrete (socketed, 2520 6-pin compatible)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransformers:\u003c\/strong\u003e CineMag USA (input and output)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e +71 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTone switch:\u003c\/strong\u003e 600\/150 Ohm input impedance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad:\u003c\/strong\u003e -20 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhantom power:\u003c\/strong\u003e +48V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolarity switch:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHi-Z input:\u003c\/strong\u003e 2 MOhm (front panel, JFET)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e XLR mic (rear), 1\/4\" Hi-Z (front)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e XLR, 1\/4\" TRS (balanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetering:\u003c\/strong\u003e LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput attenuation:\u003c\/strong\u003e Post-output transformer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 115\/230V switchable, IEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm factor:\u003c\/strong\u003e Half-rack desktop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 267 x 216 x 44 mm (10.5 x 8.5 x 1.75\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWarm Audio WA12 MKII (Black)\u003c\/li\u003e\n\u003cli\u003eIEC power cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Warm Audio","offers":[{"title":"Default Title","offer_id":50525613392121,"sku":"WA12-MK2-BLACK-b1","price":664.05,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/WA12-MK2-BLACK_1247a524-51b6-45f2-acb0-5098e4455a86.jpg?v=1765322121","url":"https:\/\/blackoutaudio.com\/products\/warm-audio-wa12-mk2-black-b1","provider":"Blackout Audio","version":"1.0","type":"link"}
