TTPC Matcher Series Audio Transformer

As we began to produce more and more line and impedance matching transformers, we were challenged with a stereo DSS music channel satellite system (600 Ohms) to stereo amplifier system (10K Ohms) for a large food chain. But 'Keep It Simple Stupid' (KISS). Keep it inexpensive and keep the sound top quality. We must maintain stereo and that would require two transformers with color-coded leads. That is too complicated and expensive to install. A small, easy to mount, printed circuit board with two transformers in a box with phono type connectors was proposed and quickly approved and delivered. The part number was S2S600/10K. As time passed, several other applications were proposed using the PCB and two custom matching transformers without the box. Orders were received and delivery was quick. A new, more versatile circuit board was designed that would allow for resistors and capacitors to be added with the transformers offering a perfect match, extended frequency response, roll off and etc. This marked the beginning of a dual transformer product line, easy to use, easy to mount and at the right price.

Several standard products are as follows with customs as easy, as quick and as cost effective as apple pie.
