Instead of using the usual signals, this SparkDIGI offers you to enjoy an extremely clean I2S LVDS signal via a dedicated Audio-GD digital interface. The latter is responsible for symmetrizing the signal. All you have to do is plug the SparkDIGI into your DAC with an HDMI I2S LVDS port to enjoy your music and exceptional sound reproduction.
Attention: the HDMI output is only I2S balanced and is therefore not usable for video. It will soon be available from this page.
