The 312 is one of API's most sought after and famous mic preamps.
First introduced in the 1970s, it is well known and respected throughout
the recording industry, and is the building block of the modern 3124
rack unit.
Based on API co-founder Saul Walker's original designs, the API 312
Mic Pre combines our 2520 op-amps and proprietary transformers. It
delivers the analog warmth, massive headroom and unmistakable sound for
which API is known, in a convenient 500 Series format.
Following the success of the hand wired 312 50th Anniversary Edition,
this standard production version offers the classic API sound at an
affordable price. Like all API products, the 312 is backed by API's
unique Five Year Warranty.
