Denafrips Gaia 12Th: Powerful digital interface

Denafrips Gaia 12Th
Denafrips Gaia 12Th

Denafrips Gaia 12Th is the result of three years of research and development by a brand with significant experience in the design of DACs and related technologies. This interface allows you to expand the digital compatibility of your audio system or computer while improving sound quality.

Denafrips Gaia 12Th

Gaia works perfectly with a wide range of brands and models of DACs on the market. The incoming USB digital signal data stream is stored in a FIFO buffer and then re-clocked using the on-chip femtosecond oscillator. This procedure significantly minimizes jitter, ensuring a signal free of digital noise. Additionally, Gaia 12th provides galvanic isolation, protecting the signal from electrical noise and maintaining signal integrity throughout the conversion process.

What is DDC?​

A DDC or Digital Converter converts a digital audio signal from one format to another. Its main purpose is to facilitate interconnection between different audio devices. In addition to this conversion, Denafrips Gaia 12th uses advanced processing techniques to improve the quality of the output signal.
