The Ultimate Match Master

Thursday, July 18, 2013


The UMM transformer has a unique design and winding method that has been developed to produce an unusual and top performance. It is an impedance matching transformer to meet all your needs. There are 13 models at this time, with more to come.

Each unit has three separate primary/input possibilities and three secondary/output possibilities. The primary and secondary are each small autotransformers that can be used as an isolation transformer. The UMM is designed for a flat frequency response and very low noise+THD. Each unit has maximum voltage inputs specs for 20Hz. and 40Hz.

Initially, the UMM will be available as dual units on a PC board with Euro terminal inputs and outputs, much like our TTPC series. This PC board's designed and layout are done for best performance.


We suggest you try a UMM-PC unit to test out. The introductory price is 25% off. This offer expires September 30, 2013. We will start shipping early in August.

The individual PC mounted transformers will be available September 1, 2013. We are also developing a webpage so you can mix and match the transformers on your UMM-PC.
