API 312 - 500-Series Mic Pre Module

The API 312 is 500 series adaptation of API's original 312 microphone pre-amp. The 312's design is based on Saul Walker’s original designs and includes API’s 2520 op-amp and AP2516 transformer.

The API-312 is one of API's most sought after and famous mic pre-amps. 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 analogue 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.
