Digital S/PDIF audio output mod kit for the Super Nintendo

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.

Wow just Wow

Never expected my SNES to sound so full for lack of a better term. Install was very straight forward and product was high quality. Would recommend to any Audiophile/Retro Gamer.

Everything I hoped for

With my OEM SNES pre-mod I experienced analog background noise and have never been able to get it to play nice with my capture card where the audio wasn't desync'd. With this mod installed, the sound is crystal clear and having the audio independent from the video output means I can pipe it directly to my PC, eliminating the audio lag!

Installation is definitely involved, but easily doable if you have the right soldering equipment. With a multimeter to check for bridging and the comprehensive online install documentation, I was able to successfully install the audio encoder the first attempt. When soldering the encoder to the chip, it helped me when I pre-tinned the arms and utilized a generous amount of flux on the wire.

excellent product - super famicom 1chip crystal sound

My console, super famicom 1chip, was in a regular case, not junior. I found on you tube the channel of the author of this mod. Having studied the issue of installation on my own and realizing that not everything fits together, since I have a different revision, I wrote to the author of the mod here on the site, and sent photos of the motherboard. Further, the creator of the mod made notes and, as the installation progressed, a clarification was added. as a result, everything worked and the sound became crystal clear! thanks to the author for the work and all the best!

Great product, great seller.

This solution is great! it is really streamlined and if you have any other mod (RGB mod, etc.) it will help you avoid the inside of your snes jr. becoming a mess. The COAX or TOSlink option is great. I need and have use for the flexibility. The extra parts provided as well as the kit are high quality. Installation is pretty straight forward, and there is no documentation provided, but the seller (who hapens to also be the developer) is super helpful in case you have any question about installation or configuration of the product. Shipping to Mexico in COVID-19 times was decent, and the seller was very helpful providing tracking numbers when the package changed carrier. The price is great considering how niche this product is.
