Denafrips IRIS DDC

A DDC, which stands for Digital-to-Digital Converter, functions as a device that transforms a digital audio signal from one format or interface to another within the digital domain. Its primary purpose revolves around facilitating harmony between distinct audio systems, particularly when confronted with diverse digital interfaces.

The Denafrips digital-to-digital converter (DDC) represents a device meticulously crafted to accept a digital audio signal in a specific digital connection, for example, USB, and subsequently convert it into an alternative digital audio outputs. This conversion process not only enhances the audio quality but also involves the application of advanced processing techniques.

Denafrips DDC employs a FIFO buffer to store and manage the incoming digital input signal. This buffering process is enhanced and reclocked by the utilization of an internal high-quality Femto clock, which ensures precise timing and synchronization. Additionally, the DDC incorporates galvanic isolation, safeguarding the signal from electrical interference and maintaining signal integrity throughout the conversion process.

Denafrips has earned a reputation for producing DDCs that excel in audio performance, driven by the integration of cutting-edge technologies to ensure precision during signal conversion, preserving the authenticity of audio data with enhancement. These DDCs serve as a crucial link in connecting disparate digital audio setups, fostering compatibility among varied audio components that might employ differing digital interfaces or possess distinct sampling rates.

A combination of 8 sets of Precision Linear Power Regulators with Ultra Low Noise characteristics, coupled with an oversized 60VA UPOCC Copper O-Core Transformer, efficiently provides clean power to the digital circuitry.

The incoming USB digital signal data-stream undergoes FIFO buffering and is subsequently reclocked using the FEMTO Crystal Oscillator. This meticulous procedure significantly minimizes jitter, guaranteeing that the resulting digital output signal remains unaffected by detrimental jitter noise.
