The API 512c remains faithful to the circuit designs of API's founder, Saul Walker. Fully featured and still hand assembled, the 512c carefully preserves the original sound character that made it so much a part of the early days of recording. Offering high headroom and a wide variety of inputs and input access points, it is equally at home in the commercial recording studio as it is in the home project studio.
The 512c Mic/Line Preamp makes use of the 2520 op-amp and therefore exhibits the reliability, long life, and uniformity which are characteristic of all API products.
