Input-Output modules with all the clarity and punch your ATR-100 can deliver.  This upgrade has been described as "removing the blanket without removing the recorder".

In other words, your recorder will still sound like an ATR-100 and that is a good thing! This mod removes the OEM "iron" (hence, XIRON) and replaces the transformers with active IC based balanced line receiver and driver modules. These supplied modules are based on Burr-Brown chips, properly configured and nested atop the main circuit board on stand-offs. Numerous other improvements include precision VU meter calibration, and upgrades to key amplifiers with faster, smoother sounding (rather expensive) B-B FET input op-amps plus a whole lot more.  Bonus: 1/2 hour or thereabouts (until I get cranky) of telephone support, only if required.

Everything except the tools and solder provided. Plus about 5 hours of your time per channel.

Additional options include:
• Spare I/O circuit boards - enabling you to keep your current I/O boards as stock.
• Final calibration, testing and check out in our shop. (Shipping is additional)

(ed: Interestingly enough, while I have yet to find a transformerless mic preamp I could live with, I do find that here on a tape based recorder at line levels, exists a good place for active balancing. Particularly when the iron being replaced is not the best quality.)
