1948 Audio Port and Voltage Extractor

Sewastopol is a multifunction eurorack module designed for easy interfacing of external gear to your modular environment. It can export line and professional level audio, import audio from instruments and electroacoustic transducers, and analyze the incoming audio to generate voltages and triggers to control your modular system. This is a second, vastly improved revision to the original 2014 Sewastopol, featuring a completely redesigned preamplifier circuit, better ergonomics and various other improvements.

EXPANDABILITY: The preamplifier can be exchanged with a different circuit, for example a low impedance, or tube-based preamp. This edition of Sewastopol ships with a universal solid-state preamplifier model “877????”, based on a symmetric JFET input stage and a very low noise operational amplifier. This preamp model is our best effort to achieve very high input impedance and gain while keeping noise at a minimum level. Additional preamp models may be available in the future.

• Audio input and output interface
