## Description

This mod kit enables perfect digital output from a Super Nintendo console, capable of both optical and coaxial output.  Unlike other similar devices, this kit utilizes a mini-TOSLINK output jack, which not only supports both output types, but also makes installation easier and cleaner, since it only requires a single 5mm hole, which can be easily cut with a standard drill, rather than needing to cut a square hole for a full-sized TOSLINK jack.  The boards are designed to minimize the length of wire needed for the noisy serial lines, which should help to reduce interference which can result in audio drop-out.  Instead, the final output signal is carried differentially to the transmitter board, which should also serve to eliminate interference.
