The Line In module is a simple line level to Eurorack converter. The circuit boosts the stereo input from an aux or line level source to the appropriate voltages found in the Eurorack ecosystem. The design was based on the Project 88 from ESP found here: https://sound-au.com/project88.htm The project files can be found here: <github link coming>

The Stereo Mixer is a versatile three input mixer with chaining, panning, and output attenuation. With two mono and one stereo input it can mix and pan a variety of sources, a feature not found in many eurorack mixers. The additional “thru” chaining feature allows the injection of an additional stereo mixer, or any other raw signal into the final mix. The design was based on a variety of schematics, and will be included in the design documents. The project files can be found here: <github link coming>

The Mic Pre is a simple dynamic microphone preamp. It is based around the THAT1510 preamp chip and is designed around the associated design documents for that chip. The project files can be found here: <github link coming>
