The API 512C is a mic / line / instrument preamp designed to provide a low noise, unusually good
sounding front end for all types of audio systems. Sonically, it offers the distinct API sound at an
extremely affordable price. Offering low noise (-129 EIN) and 65 dB of gain, the 512C includes
phantom power, switchable polarity, -20 dB pad and Mic/Line or Instrument selector. Front panel XLR
and 1/4 inch connectors combined with rear panel mic access allows for additional flexibility when
installed into an API Lunchbox®, API’s 10 position 500V vertical rack, or an API console.
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 2510 and 2520 op-amps and
therefore exhibits the reliability, long life, and uniformity which are characteristic of
all API products.
