API has announced the introduction of the 312 digitally controlled mic pre module for Karno’s SEPIA system. This highly anticipated release brings the legendary warmth and punch of the iconic API 312 microphone preamp to SEPIA, Karno’s innovative digitally controlled modular audio platform.

Based on the original API 312 circuit design
Designed, built, and tested by API
