512c Mic Pre

500 Series Module

From API:

The API 512c remains faithful to the circuit designs of API’s founder Saul Walker. Artfully combining those circuits with API’s proprietary transformers and the incomparable 2520 op-amp, the 512c is a highly musical and rich-sounding analog mic pre, equally at home in commercial recording spaces as it is in smaller home studios. Fully featured and still hand assembled, the 512c exhibits the reliability, long life, and uniformity which are characteristic of all API products.
