General
Information
The Extreme Preamplifier is a semi-custom kit, which means that several standard offerings are
combined to form the base, while the inputs and outputs are added as options to the base. You
can choose to have from one to six inputs, which may be a mix of balanced (XLR) and single-
ended (RCA) jacks. You can choose to have from one to three outputs, which may be a mix of
balanced (XLR) and single-ended (RCA) jacks.
While a mix of analog and digital inputs is possible, this makes the preamplifier into a different
product – the Extreme Hybrid, and thus is not covered in this manual.
This kit is relatively straightforward to build, but assumes some prior skill with a soldering iron
and some knowledge of electronic components and assembly.
