The HiZ Plug-In TX1 PCB Kit is a 1.1"(28mm) by 1.1"(28mm) printed circuit board created to be used as a high impedance or direct inject solution for coupling HiZ instruments to the low impedance inputs of professional microphone preamplifiers. The design is modular and interchangeable for endless possibilities.

The TX1 PCB is a passive design and specifically created with the Jensen JT-DB-EPC or the Cinemag CM-DBXPC transformers in mind. Either one of those fine transformers can be used however they must be purchased directly from their manufacturers.

The TX1 PCB mates perfectly with the VP312DI preamp
This PCB kit comes with (6) #3103-2-00-21-00-00-08-0 Mill-Max sockets
A 6.8K resistor is also supplied (used with the Jensen transformer)

So what is the HiZ Plug-In format all about? The HiZ Plug-In is a new concept developed by myself and Volker Mayer, aka [silent:arts]. Our thought was to have a standardized footprint for a small PCB, which can contain many different HiZ circuits for different uses and applications. It is a modular design, much like the 2520 DOA. We use the same exact Mill-Max pins that we use for our DOA projects. The footprint is noticeably different from a 2520 DOA, to help avoid any costly mishaps. The HiZ Plug-In is an open format. Open to any and all who want to experiment or create their very own, unique HiZ circuit. In fact, we welcome and encourage that. A PDF with HiZ Plug-In specifications and requirements can be found below.

***Please note: The resistor is installed on the bottom of the PCB. The leads must be clipped so they do not protrude beyond the top of the PCB and short to the transformer's metal can. Volker and I recommend only soldering this resistor from the bottom. Two of the Mill-Max pins must also be filed down at the top of the PCB, for the same reason.
