About Solid State Logic

Whether you’re listening to your favorite album, rocking out at a live concert, or watching the evening news, your experience wouldn’t be as enjoyable without excellent sound quality. One of the leaders behind this sound quality is Oxfordshire, UK-based Solid State Logic. Founded in 1969, the professional audio manufacturer develops analog and digital mixing and sound consoles for studio, live, and broadcast environments.


Some products are entirely analog designs, while others are mixed signal. Complex design sub-circuits, such as preamplifiers, consist of up to 100 discrete components that contribute to product differentiation.



  • Mitigate risks by achieving first-time-right circuit designs prior to fabrication
