Digital Formats & Ethernet

SPDIF & AeS protocol Cabling

The S/PDIF (Sony/Philips Digital Interface Format) and AES (Audio Engineering Society/European Broadcast Union), commonly referred to as AES/EBU, are both digital audio interfaces specifically designed for the transmission of high-quality, uncompressed audio signals. Each interface is tailored to distinct applications and features with unique characteristics that enhance their utility in both professional and consumer audio contexts.


S/PDIF serves as a cost-effective solution utilizing either optical or coaxial transport mediums. Although it is limited in transmission distance, it incorporates basic error correction capabilities. Standard formats associated with S/PDIF include Stereo PCM, as well as compressed multichannel formats such as Digital Dolby and DTS.


AES 3 is a robust and well-defined standard designed for application in recording studios, live broadcasting, and concert venues. AES provides a fully balanced, three-wire configuration that incorporates advanced error correction capabilities, multichannel Pulse Code Modulation (PCM), and supports extended cable runs. Furthermore, the integration of a system word clock notably diminishes jitter, thereby improving audio quality and performance. AES 3 interfaces well with AES 10(MADI) and AES 67/Ravenna (Ethernet)

USB Cabling

USB connections to a Digital-to-Analog Converter (DAC) offer a wealth of compelling advantages over traditional S/PDIF connections, significantly elevating your audio experience. 


- Higher sample rates are available, unlocking a depth and richness in sound that standard connections cannot match.

-Asynchronous transfer modes, when supported by the DAC, enable superior management of incoming data timing.


This asynchronous data transfer, paired with an EnKlein USB cable, enables the DAC to effectively control the timing of data flow, reducing jitter compared to standard S/PDIF connections. The result? A more stable audio signal translates into clear, precise playback, enhancing your overall listening experience.

Ethernet Cabling

Ethernet represents a form of digital communication that enables multiple devices to connect within the same local area network (LAN). Complications may arise when two or more devices attempt to transmit data simultaneously, resulting in a collision. Upon detecting such a collision, all involved devices will pause transmission for a randomly determined duration before attempting to retransmit the data.  Data transmission stops entirely!


This part of the TCP/IP protocol leads to gaps in communication and diminished audio quality. EnKlein Ethernet cables are specifically designed to reduce the noise floor and mitigate voltage drops, thereby increasing receiver sensitivity and decreasing the likelihood of collisions. As a result, users can expect superior streaming experiences.


Professional systems utilizing Ravenna or AES67 achieve lower latency, support a broader range of data formats, while increasing reliability.
