A legend, reborn.
DIY made easy.

The DA 87i DIY Microphone Kit includes a beautifully designed body, premium components, shockmount, aluminum flight case, and crystal-clear full-color printed instructions to guide you every step of the way.

The DA 87i in action.

A legendary circuit.
Updated for DIY.

The simplicity of a single main PCB makes it easier than ever to build your DA 87i. Several improvements have also been made to reduce assembly time and enhance long-term reliability.

Tantalum capacitors have been replaced with high-quality electrolytics and multiple high-impedance connections utilize point-to-point soldering, which maximizes performance and keeps the noise floor low.

The all-new DA 87i combines the most sought after microphone circuit with premium components that are sure to impress even the most discerning purists. Every aspect of the DA 87i has been meticulously designed to create a microphone that captures your performance with the famous, vintage tone you’ve been chasing.

Hearing is believing.
Choose your capsule.

The DA 87i DIY Microphone Kit is available with your choice of K87 capsule — the standard RK-87 capsule offers great performance at a price that will make your wallet happy, and the DA-K87 offers remarkably smooth highs thanks to its American-made 6-micron gold-sputtered membranes.


Electrically insulated backplates and dual Japanese 3-micron gold-sputtered mylar diaphragms.

Dachman DA-K87

Electrically insulated backplates and American-made 6-micron, gold-sputtered mylar. Captures a balanced, natural tone that's reminiscent of the original, vintage capsule.

Premium components.
No compromises.

When you build your kit with components selected for quality and tight tolerances, you’ll have a microphone that not only sounds great, but one that lasts you a lifetime, too.
