The 312 500 Series mic preamp houses a modern production version of the vintage 312 circuit used in API consoles from the 1970s. API engineered today's 312 to be faithful to the original, right down to the smallest details. Built on a meticulous reproduction of Saul Walker’s original 312 PCB, today's 312 is a fully discrete design with API's storied 2520 op-amp, AP2516 input transformer, and a vintage-style analog VU meter and peak LED indicator.
