Description

 

Phantom-powered dynamic mic preamp based on the FetHead. A very similar circuit is also used in the Cloudlifter.

 

STL files for a 3D printable enclosed are included in the attached zip file, as well as a template PDF for shielding, which can be printed and glued to aluminum foil and cut out. Be sure to 3D print both the body and the lid.

can you use this on a condenser microphone ?

zipdox Reply

No because condenser mics require phantom power.

First of all, thanks for your great work! But can you tell me a little more about the shielding? How does it work, why is it rolled up at the bottom, does the aluminium belong on the inner or outer side? Also, can i use an aluminium enclosure like a stompbox, or will this create noise or something?
