Palmer PDIR Reversed DI Box

The PDIR from Palmer is a tool designed to convert a balanced XLR signal into an unbalanced 1/4" signal. In this sense, it accomplishes the opposite goal of a DI box. The common DI box, among other things, converts signal from an unbalanced 1/4" connection to a balanced XLR signal. You'd use it to run something like a guitar into a mixing console.

Here the effect is reversed. Use the PDIR to run signal from a dynamic microphone into a guitar amplifier, doing so without introducing unwanted noise. Furthermore, the PDIR isolates both connected devices from each other using a transformer.
