Essential Info

Give your PC a plug and play digital output that supports 24Bit / 96kHz. The RedKey from Firestone Audio, is the most compact and affordable 24Bit USB to S/PDIF Converter. The RedKey plugs into a free USB slot on your PC and puts out clean digital audio via a coaxial S/PDIF output to be fed into your Digital to Analog Converter (DAC) or other Coaxial digital accepting devices and uses a standard Digital Coaxial Cable. The RedKey Works without having to load any additional drivers and operates with any Mac, Windows PC and Linux PC.

There are two other Firestone Audio Keys in the series and each does something different. The BlackKey is a USB headphone DAC. The GreenKey is a USB isolator and is designed to fix electrical noise issues coming through your USB connection.
