The CAPI Heider FD312 H2 500 Series Mic / Line Preamp is a masterclass in marrying vintage charm with modern engineering. Inspired by the legendary preamps from Wally Heider Recording Studio 4, this preamp is the sonic cornerstone for any recording enthusiast seeking that classic analog warmth without compromising on clarity. At the heart of its unique sound are the custom exclusive CAPI RE-0887 input transformer and the potted CA-0252 discrete opamps, known for their buttery smooth mids and detailed soundstage.

Designed to stand out in a crowded 500 series market, the FD312 H2 has been meticulously re-engineered to include a crowd-favorite 80Hz High Pass Filter and a versatile impedance load switch. You can effortlessly toggle between MIC and LINE modes, with phantom power automatically disengaging in LINE mode for seamless operation. The fader and active booster stage, reminiscent of vintage API consoles, offer a range of gain combinations, letting you tailor your sound with precision. Whether you're capturing the subtle nuance of a vocal or the dynamic punch of a drum kit, this preamp delivers an immersive 3D audio experience.

Hand-assembled and rigorously tested in Nashville, Tennessee, each unit embodies CAPI's commitment to quality and authenticity. This is not just a piece of gear; it's a bridge to the golden era of recording, now accessible in your studio.
