  • The Firestone Audio GreenKey is a USB Isolator and is designed to solve electrical noise problems coming through a USB connection of a computer that can influence the audio signal. The most important part of digital audio is the clarity of the data travelling along the USB cable. Since the very beginning of PC based audio, the noise from the power lines has effected the data integrity creating problems with the timing of the digital signal, known as jitter. With the growing popularity of digital music, jitter has become the primary source of "digititus" and the GreenKey will help reduce that interference substantially by isolating the power from the connection to the Digital to Analog Converter (DAC) that are found in all computers. The GreenKey works Plug and Play 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 RedKey is Firestone Audio's most compact 24Bit USB to S/PDIF Converter.
