Classic microphone preamp in a 500 Series module featuring a discrete circuit design with 2520 Op Amp and proprietary AP2516 input transformer



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.

    API 312 Pre-Amp on Bass Drum
    I am using this preamp with a Sennheiser E901 in a bass drum as a second mic. It works great, good punch and sounds slightly warmer than an API 512V. The vintage style analog VU meter looks really cool but also gives a great visual on what is happening.
