GreenKey

USB Isolator. Get clean USB signal !

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 via the humble PC, 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 DAC.
The green Key works Plug & Play with any Mac, Windows PC and Linux PC.
