Designing an Authentic, DIY-friendly LA-4 Opto Cell February 7, 2018 14:35

Today we're debuting a new monthly video series called, "From the Bench." In these videos, I'll show you what we're working at the moment and talk a bit about the technical challenges of the design.

 As you may have read, we've been working on the OLA5 Optical Compressor kit for almost a year now. The OLA5 will be a 500-series opto compressor based on the Urei LA4.

In fact, it shares the exact sidechain circuit as the LA4. But getting the sidechain just right has been one of the the biggest design challenges of the project. We've finally arrived at something we're really excited about, which I go through in detail in the video.
