The API 512v is a mic/line/instrument preamp, world famous for its ability to provide a low noise (-129 EIN) front end and exceptionally good sound for all types of audio applications. Sonically, it delivers the instantly recognizable API sound at an affordable price and in the scalable API 500 Series format. Offering an impressive 65dB of gain, the 512v includes front-panel variable output control, switchable 3:1 output transformer selection, phantom power, switchable polarity, -20dB pad, and mic or instrument/line selector. The front panel Combo-type XLR and 1/4-inch connector combined with rear panel microphone access allows for additional flexibility when installed in an API® lunch box, API 10-position 500V vertical rack, or in an API console.

The API 512v stays true to API founder Saul Walker's circuit designs. Expertly combining these circuits with API's proprietary transformers and the unrivaled 2520 operational amplifier, the 512v is a highly musical, rich-sounding analog mic pre, equally at home in commercial recording spaces and smaller home studios. Fully featured and still assembled by hand, the 512v exhibits the reliability, long life and uniformity that are characteristics of all API products.
