This API 512c has been fully tested by our expert team and comes with a money back guarantee and lifetime support. 

We have a second 512C from the same production run if you need a pair.

The API 512c is a single-channel mic/line/instrument preamp in API's 500 Series lineup. It's prized for its clean, low-noise front end and delivers 65 dB of gain along with phantom power, switchable polarity, a -20 dB pad, and a Mic or Instrument/Line selector. Built on API's classic discrete circuitry and the renowned 2520 op-amp, it produces the punchy, forward "API sound" that works well on vocals, drums, and just about any source — making it one of the most widely used preamps in the 500 Series format.
