The Duette


\


This is an older project that I never took pictures of, but since it's been in use for the past few years I figured it was time to make space on the website.  The Duette is a very simple two channel mic/line preamplifier using Lundahl mic input transformers and 990 opamps.  The sound is clean with a nice direct character typical of it's lineage-- the API preamps.  
The case is taken from an old power supply that also provided the template for the front panel design.  Options include mic or line input and transformer balanced output or unbalanced.  It sounds great with the Coles ribbon mic in the studio.
